The Audi Q5 hybrid quattro combines the performance of a
six-cylinder with the fuel economy of a four-cylinder. The highly
variable interior offers plenty of room for recreation and family. The
vehicle is powered by a 2.0 TFSI producing 155 kW (211 hp) and an
electric motor producing 40 kW (54 hp). This combination provides for a
system output of 180 kW (245 hp). The average fuel consumption measured
according to the NEDC is just 6.9 liters per 100 km (34.09 US mpg). The
quattro permanent all-wheel drive system and an agile chassis are an
unbeatable technology package.
During the development process,
Audi focused on a high share of electrically powered driving. The
sportiest hybrid SUV on the market covers about three kilometers (1.86
miles) with zero local emissions at a constant speed of 60 km/h (37.28
mph), and can drive at up to 100 km/h (62.14 mph) under electric power
alone.
The Audi Q5 hybrid quattro is the perfect car for an
active lifestyle. It is efficient, dynamic, spacious, multifunctional
and comfortable. It will be appearing in the fourth quarter of 2011 at a
starting price of EUR 53,700.
Proportions
The Audi Q5 hybrid
quattro is 4.63 meters (15.19 ft) long and 1.90 meters (6.23 ft) wide,
but only 1.63 meters (5.35 ft) high, giving it the sportiest proportions
in its market category. Its drag coefficient of just 0.32 also
represents a top figure for its category. The design is elegant and
sculptured - typical for Audi, which is the leading brand in this
domain.
Exterior cues identifying the Audi Q5 hybrid quattro are
hybrid badges on the sides and on the rear, the single-frame grille
painted in high-gloss black, the exclusive body color Arctic Silver,
19-inch wheels in a ten-arm turbine design and chrome trims on the
tailpipes.
The headlights are optionally available with xenon
plus lamps and LED daytime running lights, in which case the rear lights
also use LEDs.
Rising lines dominate the side view. The elegant
roof contour, crowned by low-height roof rails, accentuates the slim,
coupe-like appearance of the Audi Q5 hybrid quattro. The wrap-around
tailgate, like the engine hood, is made from lightweight aluminum.
The
wheelbase measuring 2.81 meters (9.22 ft) provides for a generously
spacious interior. The seats are ergonomically shaped and versatile in
their layout. The angle of the rear seat backs can be adjusted, and they
can be laid flat very easily - it suffices to operate the release
catches in the cargo area so that they can be folded down onto the seat
cushions. This increases the cargo volume from 460 to 1,480 liters
(16.24 - 52.27 cu ft). The lithium-ion battery cells are located in a
crash-proof area beneath the cargo floor, minimizing their impact on the
cargo volume.
Out in front: the safety equipment
The body of
the Audi Q5 hybrid quattro contains a high proportion of high-strength
and ultra-high-strength steel components. These reduce weight while
simultaneously improving crash safety, rigidity and vibrational
behavior. The front seat belt force limiters and airbags act together in
a new, highly intelligent way.
All of the conductive components
throughout the entire high-voltage system are electrically isolated,
i.e. there is no electrically conductive connection with the rest of the
vehicle. Consequently, there is no elevated risk of electrocution. The
high-voltage system of the Audi Q5 hybrid quattro is deenergized
automatically upon activation of the belt tensioners or the airbags.
Inside,
the Q5 hybrid quattro presents a variation on Audi's clear, elegant
design language. The cockpit has a bias towards the driver; its controls
can be operated with intuitive ease. The new display concept with the
power meter shows the driver the overall output of the system on a scale
from 0 to 100 percent. At the same time, the large MMI monitor also
shows the operating states.
Aluminum links: the suspension
The
chassis also underscores the dynamic character of the Audi Q5 hybrid
quattro. Ride height was lowered by 25 mm (0.98 in) to reduce driving
resistances. The direct steering ratio closely connects the driver to
the road. The five-link front suspension and trapezoidal-link rear
suspension are made substantially from aluminum, and the low-mounted
electromechanical steering gear transmits steering wheel movements
directly to the wheels. Large, 17-inch brakes provide for powerful
deceleration. 19-inch alloy wheels with 235/55 tires are standard, with
wheels measuring up to 20 inches in diameter available from Audi as
options.
Audi's hybrid SUV drives with sporty precision and
unwavering stability, while always providing a comfortable ride. The
switch between electric and conventional drive is imperceptible. Its ESP
stabilization system incorporates new functions that the competition is
unable to match. For instance, the ESP has a sensor that identifies
when a roof rack is mounted and then knows that the Audi Q5 hybrid
quattro's center of gravity is higher. This is significant, because the
roof load may be as much as 75 kilograms (165.35 lb). In this case, the
ESP cuts in slightly earlier as the handling limits are approached. This
allows the system to apply a very dynamic basic characteristic.
The
standard hill descent assist makes driving down steep slopes safer by
holding the speed below 30 km/h (18.64 mph). The ESP and ABS have
special mapped characteristics for offroad driving. The ESP emphasizes
maximum traction in off-road conditions. The ABS automatically
identifies the surface conditions and selects the ideal control strategy
for sand, gravel or scree.
Audi's new performance SUV is
generously equipped. Standard equipment includes automatic air
conditioning, onboard computer with color display, MMI navigation plus
with energy flow display and the Audi sound system. In combination with
the Bluetooth online car phone, this version of the MMI navigation plus
with hard drive and DVD drive offers the ability to use images from
Google Earth for the navigation system and to use online services. A
Wi-Fi hotspot is then also available for mobile devices.
Optional
digital radio reception or an interface for the iPod or MP3 player with
USB connection are perfectly integrated into the high-end sound system
from the Danish specialist Bang & Olufsen.
Assistance systems: luxury from the full-size category
Upon
request, Audi can equip the Audi Q5 hybrid quattro with high-tech
systems adopted from the full-size category, making driving an even more
controlled, relaxing affair. The Audi parking system advanced employs a
reversing camera to aid the driver in maneuvering; Audi lane assist
helps the driver to maintain the lane; and Audi side assist alerts the
driver to potential hazards during a lane change.
The other
equipment items likewise underscore the Audi Q5 hybrid quattro's status
as a performance model. These include the convenience key for keyless
access, a large panoramic sunroof, three-zone automatic air
conditioning, roller sun blinds for the rear side windows and the Audi
adaptive light dynamic cornering light system. The high-beam assistant
switches automatically between high-beam and low-beam headlights. The
front seats can be adjusted, heated and cooled electrically.
Exterior design
Every
Audi makes its dynamic nature visually apparent at first glance. The
Audi Q5 hybrid quattro also has the sportiest proportions in its vehicle
segment. It measures 4.63 meters (15.19 ft) in length and 1.90 meters
(6.23 ft) in width, but only 1.63 meters (5.35 ft) in height. Its body
design comes across as powerful, athletic and emotionally charged. With
the new Q5 hybrid quattro, the Audi brand once again underscores its
leadership in automotive design.
The Audi Q5 hybrid quattro is
distinguished by visual features on the outside. The tailgate, the
fenders and the aluminum sill panel strips bear the hybrid badge. The
radiator grille is painted high-gloss black, and the tailpipes feature
chrome trims. The exclusive Arctic Silver, metallic paint finish is
optionally available.
The 19-inch cast aluminum wheels feature a
ten-arm turbine design, with their spokes resembling turbine blades. The
wheels are fitted with 235/55 tires. Audi offers optional wheels with
19- and 20-inch diagonals; an S line bumper is available from quattro
GmbH.
With their slightly angular cut, the headlights lend the
Audi Q5 hybrid quattro's face an air of resolve. The optional xenon plus
headlights are an elegant setting for the daytime running lights,
comprising 12 daylight white LEDs each. The xenon plus headlights can
also be combined with the adaptive light cornering light system.
Like
the front end, the rear of the Audi Q5 hybrid quattro has a strongly
expressive character; horizontal lines accentuate the impression of
width. The bumper incorporates the rear fog lights, and the license
plate area is recessed into the tailgate. Like the engine hood, the
wraparound tailgate is made from lightweight aluminum. It is
exceptionally wide, like that of its big brother, the Audi Q7.
The
undivided rear lights are mounted on the large tailgate. Because they
are not visible when the hatch is open, the Audi Q5 hybrid quattro has
auxiliary lights in the bumper. The main lamps have bulbs housed in
separate chambers as standard; Audi uses light-emitting diodes in the
optional xenon plus headlights.
Body
Good design is always
functional design - the Audi Q5 hybrid quattro has a drag coefficient of
just 0.32, the best in its segment. This is attributable to the
intensive fine-tuning of the body and the underbody. The frontal area of
the performance SUV measures 2.65 m2 (28.52 sq ft).
The body is
unusually light in weight; the tailgate and the engine hood are
aluminum. The rigid body shell incorporates hot-stamped steel in
numerous places, combining low weight with very high strength. Despite
the generous level of standard equipment, the Q5 hybrid quattro with its
curb weight of 1,910 kg (4,210 lb) is the lightest hybrid SUV on the
world market. All its hybrid components add less than 130 kg (287 lb) of
extra weight.
Ultra-precise: welding and bonding
The way the
body is put together is also a highly precise affair. The areas in which
conventional resistance spot welding is used now account for only 73
percent of the total - equivalent to about 5,000 weld points. To boost
strength further, Audi uses bonding in some areas as well as or instead
of welding. A two-component adhesive forms the bond in 17 percent of the
cases; the adhesive seams measure a total length of 83 meters (272 ft).
There
are two particularly elaborate joining technologies among the remaining
10 percent. Laser welding is the method of choice around the sills and
on the doors. The components in the visible part of the tailgate's water
channel, like the zero gap between the side section and roof, are
joined by high-tech soldering methods. This zone is visible evidence of
Audi's uncompromising quality philosophy, epitomizing the precision
joints running all across the body.
The use of ultramodern
materials and joining techniques is the basis of the body's rigidity. It
keeps the noise level on board low and paves the way for superb
drivability - it is the basis for both low tire noise and sporty,
precise handling.
Uncompromising: long-term quality
Long-term
quality is again a top priority in the Audi Q5 hybrid quattro, in
keeping with the brand with the four rings. To protect against
corrosion, all body cavities are flooded with hot liquid wax. Audi is
the only premium brand to implement this method.
Maximum safety: the special features of the Audi Q5 hybrid quattro
Like
every Audi, the Q5 hybrid quattro satisfies the stringent safety
standards which the brand with the four rings requires of all its
vehicles. A comprehensive safety package begins with the high-strength
occupant cell and includes front, side and head airbags, the integral
head restraint system in the seats, the belt tensioners and a
sophisticated system of sensors that initiates the protective measures
necessary for the situation at hand.
Thanks to its spacious
crumple zone, the Audi Q5 hybrid quattro meets all Japanese and European
requirements for collisions with pedestrians. In the type-specific
crash, which involves driving into a barrier at 15 km/h (9.32 mph) and a
40 percent overlap, crash boxes made from aluminum located ahead of the
longitudinal members prevent damage to the body structure. The radiator
can be displaced slightly to the rear thanks to its sliding mounts.
Minor bumps at up to 4 km/h (2.49 mph) when maneuvering in parking lots
do not leave any dents in the aprons, and these components can be
replaced individually after collisions at higher speeds.
Special
attention was paid to the concept-specific requirements of a hybrid
vehicle. The Audi Q5 hybrid quattro has special protective mechanisms
that are triggered in the event of a hazard. All of the conductive
components throughout the entire high-voltage system are electrically
isolated, i.e. there is no electrically conductive connection with the
rest of the vehicle. This isolation ensures that there is no elevated
risk of electrocution. Furthermore, the high-voltage components are
deenergized if the airbags or belt tensioners are triggered.
Cargo area
The
Audi Q5 hybrid quattro is the performance SUV for a dynamic, active
clientele - it displays all the talents needed in a vehicle designed for
sports, family and recreational use. Its buyers are people with a high
level of education who value an active lifestyle. Audi Q5 hybrid quattro
customers view their car as an expression of their individuality and
consequently attach great importance to attractive design, sportiness
and performance.
The cargo area is one of the Audi Q5 hybrid
quattro's practical strengths. In its basic configuration, it already
offers a substantial 460 liters (16.24 cubic ft) of cargo space, which
can be used very effectively. The floor is completely flat; the loading
lip is only 665 millimeters (26.18 in) high and lies almost flush with
the floor. The loading width is an impressive 105 centimeters (41.34 in)
even between the wheel arches, and the loading length 93 centimeters
(36.61 in). Four golf bags can easily be stowed cross-wise, and the
maximum payload is a hefty 580 kilograms (1,279 lb).
The extended
cargo area has a capacity of 1,480 liters (52.27 cubic ft) (loaded to
roof height) and a loading length of 170 centimeters (66.93 in). It can
be significantly increased yet again by the convenient option of a
folding front passenger's seat, with special kinematics to fold its seat
back down forwards. The standard rear bench seat plus makes the cargo
area even more variable. This can be slid forward by 10 centimeters
(3.94 in) and also incorporates a large load-through hatch. The seat
back of the slightly narrower center seat (40:20:40) is designed to fold
down individually. The standard strip of stainless steel for the cargo
area offers protection during loading and unloading.
The optional
trailer hitch can be pivoted out, and light-emitting diodes indicate
whether it is correctly locked in position. The accessories range
includes various racks for transporting bikes, canoes, surf boards and
skis on the roof.
Interior
Feeling immediately at ease is a
typical response when climbing into a new Audi. The Audi Q5 hybrid
quattro is no exception; its developers have created a light, luxurious
and spacious interior. It is elegant in appearance, the build quality is
of the customary superb standard, and the intuitive ease with which it
is controlled can be further enhanced with numerous high-tech features
from the full-size category.
The driver's and passenger's seats
offer an ergonomically excellent seating position and support the body
perfectly. The standard seats are height-adjustable, and their head
restraints can be raised a large amount.
Audi offers the option
of sport seats with manual angle adjustment, extendable thigh rest and
electric four-way lumbar support - this latter feature can also be
ordered separately. Alternatively, all-electric seat adjustment is
available for adjusting the fore/aft position, seat back angle and
height. A memory function that remembers the preferred seat and exterior
mirror positions is also available. With typical Audi thoroughness, the
optional heated seats have six settings.
The climate-controlled
comfort front seats offer the ultimate in luxury. Each seat back and
base cushion has two small fans with six power settings. To prevent
chilling of the occupant, there is a supplementary function that cuts in
automatically, if need be. The climate-controlled comfort seats are
upholstered in perforated leather.
An extensive range of design
packages is available. These include Havana cloth upholstery or the
leather grades Milano and Fine Nappa for the standard seats; these come
in a range of five colors. The sport seats are upholstered in Micron
cloth or the leather types leather/Alcantara, Milano and Fine Nappa.
Here again, the customer has a choice of five colors.
The Audi Q5
hybrid quattro's colors and equipment, too, have a sporty, elegant
character. The vehicle's interior is visually harmonious in black, gray
or beige. This philosophy creates a light interior impression in which
the inlays provide visual highlights. The standard version is in
micrometallic platinum, a metallic-effect paint finish, or optionally in
aluminum or the woods walnut brown or fine grain ash almond beige. With
the fine grain ash brown version, the wood's pores remain open and thus
allow the natural material's structure to be explored by the
fingertips.
For individualists: the S line sport package
The S
line sport package creates even more sporting individuality. Besides
19-inch or 20-inch wheels and the special body colors Daytona Gray and
Monza Silver, it includes a whole array of distinctive individual
details inside the vehicle. The interior and headlining are in black,
with a choice of black or silver seams. The upholstery of the sport
seats - in cloth/leather, Alcantara/leather, Milano leather or Fine
Nappa leather - features special S line embossing. The inlays are in
matt aluminum (or optional piano finish). The leather sport steering
wheel is emblazoned with the red and silver S line badge, and the gear
knob is trimmed in perforated leather.
Feel-good factor: the perfect ergonomics
The
sense of well-being that the interior of the Audi Q5 hybrid quattro
creates is underpinned by the perfect ergonomics for the driver. The
sportily short gear knob is positioned such that the driver's hand finds
it intuitively, and the distances and angles of the steering wheel and
pedals are perfectly matched. The steering wheel has 60 millimeters
(2.36 in) of manual reach and 44 millimeters (1.73 in) of height
adjustment, with electric-motor locking.
The standard leather
multifunction sport steering wheel has four spokes; a leather
multifunction sport steering wheel with three spokes is available as an
option. It has small drum-type and pushbutton controls for the basic
functions of the navigation system, radio system, car phone and speech
dialogue system. These are elegantly framed with narrow chrome
surrounds.
All functions in the Audi Q5 hybrid quattro are
focused on the person at the steering wheel. The center console, which
is subtly angled to the left, comprises a unit with the instrument
cluster. It features an innovative display concept that renders the
individual driving states of the hybrid drive clear-cut and tangible.
The tachometer has been replaced by a "power meter," with a needle that
indicates the total system output on a scale of 0 to 100 percent. A
second scale is divided into colored segments, whose green and orange
sections show at a glance how the Q5 hybrid quattro is currently
traveling - with a greater share of electrical power or combustion
engine power. An additional instrument displays the charge level of the
battery.
At the same time, the color display of the driver
information system and the large monitor of the standard MMI navigation
plus show the operating states and power flows in the hybrid system in
elegant graphics with a three-dimensional effect. The MMI monitor also
displays differentiated consumption and recuperation statistics in
easily understandable bar graphs.
Powerful and efficient: the automatic air conditioning
The
Audi Q5 hybrid quattro comes standard with automatic air conditioning
with a pollen and recirculated-air filter, plus a function that
incorporates the sun's position into how it operates. A powerful blower
circulates large quantities of air. Typically for Audi, the innovative
system is quiet, powerful and efficient. And it is remarkably light in
weight.
The climate control system of the Audi Q5 hybrid quattro
was also adapted to the requirements of electric driving. The air
conditioning compressor has a high-voltage electric drive.
Demand-controlled for high efficiency, the compressor ensures AC
operation even when the combustion engine is shut down. An electric
auxiliary heater supports interior heating.
The optional deluxe
automatic air conditioning has even more features - it regulates the
temperature, volume and flows of air in three separate zones for the
driver, front passenger and rear passengers. A responsive moisture
sensor minimizes the risk of window fogging, and separate outlets on the
top of the dashboard provide low-draught indirect ventilation.
The
interior of the Audi Q5 hybrid quattro is like a perfectly tailored
suit - it is airy but cut to fit perfectly. The statistics prove how
spacious it is: elbow room is 1,527 millimeters (60.12 in) up front and
1,494 millimeters (58.82 in) in the rear. The Audi Q5 hybrid quattro
also has an exceptional amount of front headroom - 1,043 millimeters
(41.06 in).
Even tall passengers will find the rear compartment
amply spacious. The seats provide a sporty standard of comfort at head,
elbow and knee level; there is space for the feet under the front seats.
The seat back angle of the standard seats can be adjusted between 24
and 30 degrees. The long door cutouts, the wide opening angle of the
doors and the low sills maximize ease of access to the rear of the Audi
Q5 hybrid quattro. The holders in the doors can even accommodate large
1.5-liter (50.72 fl oz) bottles. A fold-out center armrest provides
comfortable arm support, and optional nets are available for the backs
of the front seats.
Versatile: the rear bench seat plus
A
versatile feature is the standard rear bench seat plus; the sections of
the 40:60 split bench can be slid forward or back independently by 100
millimeters (3.94 in). Its center armrest incorporates two pull-out cup
holders. Other extras are manual blinds for the side windows - a feature
that will be particularly appreciated by children when out and about in
the summer.
There are numerous convenient features up front,
too. The spacious door pockets have brackets that are also suitable for
large bottles. Then there are two more cup holders on the center tunnel.
One of them is optionally available as a thermal cup holder. An
electronically controlled peltier element - an electrothermal converter
similar to the principle found in a cooler bag - operates in tandem with
a fan. At the push of a button, it cools or heats the inside of the
thermal cup holder across a range from 3 to 58° Celsius (37.4 to 136.4°
F). A small display serves as a visual reminder for the user when the
cup holder is hot.
The front center armrest is a particularly
comfortable option - it can be adjusted lengthwise by 6.5 centimeters
(2.56 in) and to four different heights. The unit has a soft foam
exterior and is particularly large thanks to the absence of a handbrake,
instead of which there is the electromechanical parking brake.
Engines and transmissions
The
2.0 TFSI in the Audi Q5 hybrid quattro has a displacement of 1984 cc.
Its output is 155 kW (211 hp), with the maximum torque of 350 Nm (258.15
lb-ft) permanently available at 1,500 to 4,200 rpm. The 4-cylinder
engine combines direct injection with turbocharging - typical for the
Audi philosophy of downsizing, which replaces displacement by forced
induction. The Audi valvelift system (AVS) further increases power,
torque and efficiency by switching the stroke of the exhaust valves
between two stages depending on the load and rpm.
The 2.0 TFSI
has been overhauled in some respects for use in the Audi Q5 hybrid
quattro. The drive of the ancillary units has been dropped, and the
crankshaft bearing and fine tuning of the turbocharger have been adapted
to the specific demands.
A secondary air system at the cylinder
head makes sure that the exhaust gas treatment cuts in particularly
fast. Integrated in the engine control unit, the hybrid manager controls
the efficient change and smooth transitions between the operating
modes, and was fully developed by Audi alone.
The optimal
interplay between the combustion engine and the electric motor briefly
results in a peak system output of 180 kW (245 hp) and a maximum system
torque of 480 Nm (354.03 lb ft).
Drivetrain
A largely modified
eight-speed tiptronic serves the power transmission without the aid of a
torque converter. Its place is taken by the disk-shaped electric motor,
combined with the multi-plate clutch operating in an oil bath - it
couples and decouples the electric motor and the TFSI. The innovative
decoupler operates with high precision, smoothly and quickly in any
situation.
The highly comfortable and fast-shifting hybrid gear
unit contributes significantly to the efficiency of the Audi Q5 hybrid
quattro - its eight gears are widely spaced. When the 2.0 TFSI is turned
off, an electric pump maintains the oil pressure in the hydraulic
system to safeguard the convenient start-stop feature.
The power electronics and the electric motor
The
power electronics, connected to the battery and the electric motor by
high-voltage cabling, is located in the plenum chamber of the engine
compartment. In the form of a pulse-controlled inverter, the power
electronics serves as a controller between the battery, which outputs
direct current, and the electric motor, which operates on alternating
current.
Innovative technologies keep the volume and weight of
the power electronics low, with cooling provided by a separate
low-temperature water-filled circuit. The component includes a DC/DC
converter that couples the electric consumers in the 12 V electrical
system with the high-voltage network.
A permanent magnet
synchronous machine serves as an electric motor, as a starter and -
during deceleration - as a generator. It delivers up to 40 kW (54 hp) of
power and 210 Nm (154.89 lb ft) of torque. The electric motor is
integrated in the engine's cooling circuit.
The battery
A
lithium-ion battery system, weighing a mere 36.7 kg (80.91 lb), serves
as the energy store for the electric motor of the Audi Q5 hybrid
quattro. The compact unit with its 26 liter (6.87 US gallon) capacity is
positioned in a crash-safe area under the cargo floor, with hardly any
intrusion on the cargo area. The battery consists of 72 cells. At 266
volts, its nominal energy is 1.3 kWh and its output 39 kW.
The
lithium-ion battery is cooled by air in two ways, depending on the
requirement. At low-temperature load, it draws temperate air from the
vehicle interior by way of a fan. If its temperature exceeds a certain
limit, a separate refrigerant circuit is activated. It is coupled to the
main climate control system of the vehicle and uses a separate
evaporator.
This heavy-duty active cooling system distinguishes
the Audi Q5 hybrid quattro from many other hybrid vehicles, and makes a
key contribution to the high electrical availability of the hybrid
system.
The operating modes
With its parallel hybrid system,
the Audi Q5 hybrid quattro can travel in five different operating modes.
Driving with the combustion engine alone, with the electric drive alone
or in hybrid mode is possible, as are recuperation and boosting.
At
a standstill, e.g. before starting or at a traffic light, both drive
sources are deactivated. In this convenient start-stop mode, the climate
control system remains active. Once the driver releases the brake, the
Audi Q5 hybrid quattro starts rolling.
The driver can change
between three programs using a button on the center console or a
selector lever. The EV characteristic map gives priority to the electric
drive in the city; the D mode controls both motors for optimal
consumption; and the S mode as well as the touch control gate of the
tiptronic are designed for a sporty driving style.
When the
driver accelerates sharply, the combustion engine serves as a power
source for the drive. The electric motor is then actuated by the
operating strategy in order to achieve optimal efficiency and
consumption. In quick acceleration, or "boosting," the electric motor
operates together with the TFSI; at full throttle in the S mode the full
system output of 180 kW (245 hp) is briefly available. The hybrid drive
with its 480 Nm (354.03 lb ft) of torque then supplies the propulsion
power of a large naturally aspirated engine, but with far more
efficiency.
When the driver releases the accelerator, the
electric motor acts as a generator and recovers energy. In most
situations, the TFSI is then decoupled from the drive system so as not
to cause any loss from towing. The electricity recovered by the electric
motor here and in braking is buffered in the lithium-ion battery. If
the driver brakes only slightly, the electric motor performs the
deceleration itself; in more forceful braking, the hydraulic braking
system is simultaneously activated. The brake servo is additionally
supplied by an electric vacuum pump. A complex rule-based strategy
adapts the braking to the conditions of electric driving and energy
recuperation.
The highly efficient 2.0 TFSI works together with
the electric motor to combine the performance of a six-cylinder with the
fuel economy of a four-cylinder. The sprint to 100 km/h (62.14 mph)
takes just 7.1 seconds. Top speed is 225 km/h (139.81 mph). The Audi Q5
hybrid quattro is also extremely efficient, consuming just 6.9 liters of
fuel per 100 km (34.09 US mpg) in the standard NEDC cycle, which
corresponds to CO2 emissions of 159 g/km (255.89 g/mile).
If
operated by the intelligent control system or the driver at a constant
speed of 60 km/h (37.28 mph), the Audi Q5 hybrid quattro can drive for
three kilometers (1.86 miles) purely on electric power, which means with
zero local emissions. This value is not the only benchmark set by the
Audi Q5 hybrid quattro. The top speed of 100 km/h (62.14 mph) in purely
electric mode is also unmatched by the competition.
Chassis
The
Audi Q5 hybrid quattro applies its power to the road via the quattro
permanent all-wheel drive system. The enhanced traction, road dynamics,
safety and directional stability that it delivers together make up
Audi's proverbial "Vorsprung durch Technik."
The Audi Q5 hybrid
quattro is the sportiest model in the hybrid SUV segment - its chassis
redefines the benchmark. It combines precision and dynamism with a high
level of stability and comfort. The suspension mountings, steering,
wheels and brakes have been developed for top performance and the
extensive use of aluminum reduces unsprung masses to a minimum.
The
five-link front suspension, with an ample track width of 1,625
millimeters (63.98 in), is a big factor in the dynamic character of the
Audi Q5 hybrid quattro. Because the development engineers moved the
differential further forward up the driveline and the clutch further
back, the axle could be positioned far to the front. This configuration
permits an optimal weight distribution between the front and rear axles.
Lightweight
aluminum - a material in the use of which Audi possesses an unequaled
level of experience - is used in many areas. For example, the largest
and most complex chassis component, the subframe for the engine and
front axle, is made of aluminum. Rigidly bolted to the forward
structure, it forms part of the body, and its high rigidity transmits
steering forces without any delay.
Lightweight construction: aluminum links
Aluminum
is also used in the Audi Q5 hybrid quattro for the bearing mount that
links the upper suspension control arms with the body, and for the pivot
bearing. The front suspension comprises five links per wheel - one
support link and one control arm at the bottom and two control arms at
the top. The fifth link is the tie rod that connects the
electromechanical steering gear with the pivot bearing.
All
suspension control arms are forged aluminum parts, guaranteeing low
unsprung masses and extremely precise wheel location. The anti-roll bar
is made from a high-strength tube, a design that also saves weight.
The
five-link front suspension handles longitudinal and lateral forces
separately when the car is in motion. In the lateral direction the
bearings are rigid, enhancing sporty precision and high cornering
speeds.
In the longitudinal direction, on the other hand, they
have a supple, soft response, combining the dynamism of a sports sedan
and the comfort of a full-size vehicle.
The rear axle of the Audi
Q5 hybrid quattro, with its track of 1,620 millimeters (63.78 in), is
inspired by the self-tracking trapezoidal-link rear suspension layout of
the large A8 and A6 model lines. It combines excellent drivability and
ride comfort with compact packaging. The Audi Q5 hybrid quattro offers
great advantages for sports and recreational use: the loading lip and
floor are at a low height, and the floor is flat.
The unsprung
masses have again been kept to the absolute minimum at the rear axle.
The two trapezoidal links are warm-hardened aluminum castings; the wheel
carriers are of chill-cast aluminum. The upper transverse links and the
track rods are aluminum forgings. The anti-roll bar, designed as a tube
like at the front axle, likewise combines low weight with high
rigidity.
Separate: the springs and dampers
The springs are
supported directly on the wheel carriers - an arrangement that has made
it possible to increase the ride comfort to luxury-car level and improve
the road dynamics to the standard of a sports sedan. The separate
springs and dampers also improve response; special rubber formulations
in the axle mounts improve boost comfort further. The new rear
suspension kinematics keep brake dive closely under control, and in this
way add to the car's sporty, dynamic appeal.
Worthy of a sports sedan: the steering
An
electromechanical unit serves as the steering system, with a small
electric motor generating the power. The system operates at high
efficiency, since it need not consume any energy in straight-ahead
driving. This low energy consumption improves the Audi Q5 hybrid
quattro's fuel efficiency by about 0.2 liters per 100 km.
The
Audi Q5 hybrid quattro comes standard with servotronic. Configured as a
speed-dependent power steering system, it requires only little effort
from the driver to maneuver into a parking space thanks to the high
servo boost. At higher speeds it trims back the boost level for a
superbly calm response on the freeway.
The range of wheels also
underscores the dynamic character of the Audi Q5 hybrid quattro. Audi
ships its new hybrid SUV equipped with elegant aluminum wheels in two
substantial dimensions - 19 and 20 inches. Measuring 19 inches and shod
with 235/55 tires, even the standard wheel, a lightweight cast wheel,
suggests the powerful performance of the Audi Q5 hybrid quattro with
hybrid drive. Audi offers 17-inch and 20-inch winter wheels.
Large and powerful: the brakes
The
large wheels of the Audi Q5 hybrid quattro conceal brakes that are
easily up to whatever braking tasks they may be confronted with. All
four disks - measuring 345 millimeters (13.58 in) in diameter at the
front and 330 millimeters (12.99 in) at the rear - are vented.
The
high-performance brake pads achieve high, stable coefficients of
friction and are only minimally susceptible to fading even under extreme
loads. The vented front disks no longer have any conventional cooling
ducts. Instead, the two halves of the disk are joined together by
hundreds of small metal cubes that are able to dissipate a high volume
of hot air very rapidly.
The brake calipers have a composite
design based on the floating-caliper concept. Areas calling for maximum
load resistance are made from high-strength spheroidal-graphite cast
iron. The aluminum piston housing dissipates the heat very effectively.
Despite their low weight, the brake calipers exhibit extremely high
rigidity.
All brake disks and also the aluminum cover plates are
particularly light in weight - directly benefiting the sporty handling,
by reducing the unsprung masses. The design of the calipers and rims
also benefits the customer in a very tangible way: the mechanic can
gauge the remaining thickness of the brake pads the moment a car is
brought in for servicing, without needing to remove the wheels.
The
ESP stabilization system also emphasizes the Audi Q5 hybrid quattro's
sporty behavior. It operates with a new type of high-precision hydraulic
valves that manage the pressure buildup with particular accuracy. It
runs without any of that all-too-familiar jolting, or obvious
vibrations.
Roof rack identification is a novel supplementary
function. The ESP detects by means of a sensor on the rails whether the
roof cross-member that comes standard with the car is mounted and
consequently whether the Audi Q5 hybrid quattro's center of gravity has
moved higher. If so, it modifies its control strategy to cut in slightly
sooner around the handling limits.
Assistance systems
Innovative
assistance systems adopted directly from the luxury class make driving
infinitely less stressful. These systems help the driver to change lanes
and stay in the lane, and assist with parking.
Intelligent
assistance systems are the latest trend in active safety - and the brand
with the four rings is leading this development from the front.
A sidelong glance to the rear: Audi side assist
Audi
side assist uses intelligent radar technology to warn of hazardous
situations when changing lanes. Two radar sensors in the rear bumper,
operating at a frequency of 24 Gigahertz, scan the area next to and
behind the Audi Q5 hybrid quattro, up to a distance of 50 meters (164
ft) from the car. A high-speed control unit analyzes the raw data.
If
another vehicle is traveling at a similar speed within the critical
range, or is approaching rapidly from behind, a yellow LED display comes
on in the left or right exterior mirror housing. Its configuration is
deliberately "subliminal." In other words, it is only visible when the
driver looks directly at the mirror; it is imperceptible while the
driver is looking straight ahead.
The LEDs brighten and begin
flashing rapidly for roughly one second if, despite the warning display,
the Audi Q5 hybrid quattro driver signals a lane change. The flash is
practically impossible to overlook because the human eye is extremely
sensitive to changes in contrast in the peripheral field of vision. Audi
analyzed the display's effect in detail in exhaustive test series
involving drivers of a variety of builds and ages.
The display's
appearance is such that in practice it is only visible to the driver. It
must not be visible to vehicles following on behind, to comply with
type approval requirements, and should not be visible to the front
passenger for psychological reasons. The brightness of the display
adapts to the ambient light conditions and can be adjusted from the MMI
operating terminal. The Audi side assist system can be deactivated at a
switch located near the exterior mirror.
Maintain the lane: Audi lane assist
Another
technology supplements the portfolio of assistance systems in the Audi
Q5 hybrid quattro - Audi lane assist. It warns the driver prior to an
inadvertent lane change. A small camera above the interior mirror
monitors the road ahead of the car, over a field of view 60 meters
(195.85 ft) long and about 40 degrees wide. A high-speed computer
sharing the same housing detects the road markings.
If the driver
approaches one of these lines without indicating, Audi lane assist
warns them by causing the steering wheel to vibrate via a motor in one
of its spokes; the intensity of this vibration can be set at three
different stages via the MMI. The timing of the warning can also be set
at three different levels - before the wheels have even reached the
lines, as soon as they cross them, or based on the system's adaptive
interpretation. Audi lane assist can also be switched off. A display
indicates if it is activated but unable to provide warnings, for
instance if the lines are too difficult to discern.
Audi offers
three parking assistance systems in the equipment range for the Audi Q5
hybrid quattro. The classic version is the rear parking system, which
acoustically signals the free distance to the rear. In the parking
system plus version, visual displays to the front and rear are added,
using a total of eight ultrasonic sensors in the bumpers.
Maximum
convenience and safety is offered by the parking system advanced, which
integrates a reversing camera. Incorporated into the tailgate, this
extremely light-sensitive camera contains a fish-eye lens providing a
generous 130-degree view of the area behind the car. Its rectified
images are displayed on the large on-board monitor.
The display
includes various guide lines and zones to help the driver position the
car correctly when reversing. When reversing into a parking bay at a
right angle to the direction of travel - the standard mode - there are
orange lines to indicate the path that the car should follow. For
parallel parking, areas shaded blue indicate the space needed for the
Audi Q5 hybrid quattro. They show whether the gap is large enough; red
and blue lines assist with the steering and countersteering process.
Multimedia systems
The
area of multimedia, in which online services, information,
entertainment, navigation and telephony all come together, is one of the
most attractive fields of contemporary and future technology. Here,
too, the Audi Q5 hybrid quattro sets new standards within its segment -
it makes its debut with an extremely wide range of technologies.
The superior solution: the MMI operating system
The
Audi Q5 hybrid quattro comes standard with the driver information
system and MMI navigation plus with its large seven-inch monitor. Both
systems use elegant, seemingly three-dimensional graphics to display the
operating states and power flows in the hybrid system. The MMI monitor
also displays differentiated consumption and recuperation statistics in
easily understandable bar graphs.
The Audi Q5 hybrid quattro
comes with the latest-generation MMI navigation plus. It has a 20 GB
hard drive for media files, the menus can be selected via a
state-of-the-art wizard, and the album tracks are displayed using the
cover artwork. An external device such as a cell phone or MP3 player can
be connected via Bluetooth, and the voice input understands town and
street names in a single command. The resonant Audi sound system is also
standard.
The optional Bluetooth online car phone makes it
possible to connect to the Internet. A UMTS model sets up the connection
to special services from Google and the World Wide Web, bringing the
latest news and weather information into the vehicle.
The driver
can plan his or her travel route at home, save the information in an
area of the internet site www.audi.com and from there download the data
into the navigation system via UMTS at the start of the trip. Through
the fast connection the hybrid SUV also downloads three-dimensional
satellite images and aerial photos from Google Earth. These appear as
bird's eye views on the monitor; the computer draws in the roads.
Another
high-end feature is the WLAN hotspot, which allows up to eight terminal
devices to connect to the Internet. Communication occurs via the roof
antenna, the connection is very stable and the reception quality
excellent. Thanks to a special modulation process, UMTS data transfer
occurs at speeds up to 7.2 MB per second. Encryption follows the WPA 2
standard - a very secure method.
The use of the WLAN hotspot is
as easy as can be - the driver need merely insert a data-capable SIM
card. At the same time the driver can pair a cell phone with the system
via Bluetooth, if the phone has the SIM Access Profile. The existing
mobile phone contract with a data option suffices in most cases with the
result that no additional charges or separate contracts are necessary.
Perfect sound: digital radio reception
Another
highlight is the option of DAB (Digital Audio Broadcasting) reception.
In terms of dynamics, clarity and spatial impression, the digital
signals that are broadcast virtually area-wide in Germany, the UK and
many other countries are easily superior to the analog standard. DAB
tuners use a computer to process the signal, while also processing
additional information for radio text.
One of the two tuners
receives the chosen station, while the other searches for other
receivable stations in the background. Even relatively weak signals are
noise-free because the dual tuner can combine the Audi Q5 hybrid
quattro's two antennas to form a single directional antenna. With the
optional Audi music interface, which is used to connect external storage
media, Audi also offers the ability to play music through the speakers
directly from external storage media.
Wellness for the ears: the Bang & Olufsen sound system
The
finest Audi sound system is from Bang & Olufsen - the epitome of
sheer audio pleasure. A wide, subtly differentiated frequency range,
sparkling brilliance, highly detailed resolution and precise spatial
impression - this system by the Danish sound wizards, adopted from the
A8 luxury sedan, is of the very highest caliber.
The two brands
Audi and Bang & Olufsen have joined forces in pursuit of the same
objectives. Ultramodern technologies, clear operation, sophisticated
technoid design and uncompromising quality are a question of honor for
both partners. Like Audi, Bang & Olufsen possesses a wealth of
expertise in the use of aluminum - the Danish company uses this material
for the speaker covers.
The key element of the Bang &
Olufsen sound system is an amplifier with an output rating of 505 watts.
It processes signals according to a specific surround algorithm, which
enables the occupant of every seat to enjoy the system's exquisite audio
quality. The system analyses the noise level inside the Audi Q5 hybrid
quattro by means of a microphone and makes selective adjustments to its
output signals in specific frequency ranges.
The amplifier
controls ten active channels with 14 speakers. There are two three-way
systems at the front, and two speakers in each rear door. The
choreography is rounded off by a center speaker in the instrument panel,
a subwoofer under the cargo floor and two surround-sound speakers.
Equipment
The
Audi Q5 hybrid quattro is a versatile, lavish SUV in terms of its
equipment and trim, too. All versions are factory-equipped with luxury
features such as automatic air conditioning, MMI navigation plus and
daytime running lights. Audi in addition offers a broad range of
equipment options, some of them adopted directly from the luxury
category. For individualists, there is a wide range of design packages
to choose from.
The Audi Q5 hybrid quattro has a comprehensive
range of technical safety systems. These include two front airbags on
either side with an adaptive operating principle that offers a
particularly high level of protective potential, two side airbags at the
front and two head airbags that unfurl along the entire length of the
windows. All seats have three-point belts, with tensioners and belt
force limiters at the front, and can be adjusted in height. In a
rear-end collision, the integral head restraint system averts the danger
of whiplash injuries.
The integration of the hybrid drive
necessitates special protective measures. All of the conductive
components throughout the entire high-voltage system are electrically
isolated, i.e. there is no electrically conductive connection with the
rest of the vehicle. In addition, the high-voltage system of the Audi Q5
hybrid quattro is automatically deenergized upon activation of the
airbags or the belt tensioners.
When it comes to comfort, the
Audi Q5 hybrid quattro is equipped with a whole series of agreeable
features. These include standard features such as power adjustable
mirrors, four power windows, central locking with radio remote control
and height-adjustable front seats. The electromechanical parking brake
offers great convenience when parking or setting off.
19-inch
alloy wheels accentuate the Audi Q5 hybrid quattro's sporty appeal. The
roof rails and inclinable seat backs provide extra variability for
carrying sports equipment and luggage.
Fine accents: the S line sports package by quattro GmbH
The
S line sport package immerses the interior in cool black, with the
inlays in matt aluminum or black piano finish providing subtle
contrasts. The sport seats are upholstered in cloth/leather or a
combination of perforated Alcantara and leather. The steering wheel,
gear lever gaiter and floor mats have a special design. Cast aluminum
19- or 20-inch wheels further enhance the dynamic appearance of the Audi
Q5 hybrid quattro.
The exclusive interior ambience is one of the
Q5 hybrid quattro's major strengths. Audi offers seven design packages,
which introduce even more finesse into the interior. They combine
various upholstery fabrics - Havana cloth, Micron cloth, a
leather/Alcantara mix, Milano leather and Fine Nappa leather - with the
standard and sport seats as well as various inlays. Aluminum elements, a
leather package and an interior lighting package complete the range of
options.
Audi has developed a wide range of intelligent solutions
for customers who are actively sporty in their leisure time. The
standard sliding rear bench seat plus, complete with large load-through
hatch, increases the size of the cargo area. The list of optional
equipment also includes an electric hatch, a ski bag, a pivoting trailer
hitch and a front passenger seat with folding seat back.
Perfect vision after dark: the adaptive light cornering light system
Where
lighting is concerned, Audi offers xenon plus headlights, the adaptive
light cornering light system, a light and rain sensor and a new
high-beam assistant. There is also an extensive range of equipment for
passive safety, including side airbags for the outer rear seats, an
anti-theft alarm and Isofix child seat mountings for the front
passenger's seat, coupled with airbag deactivation.
Seating
comfort can be even further enhanced by various luxury technologies. For
additional journey pleasure, front seat heating and electric position
adjustment - with a memory function if desired - are available, as well
as sport seats and climate-controlled comfort seats with ventilation and
automatic heating. Audi can also supply an electric lumbar support, a
front center armrest and heating for the outer rear seats.
Helping
to ensure a perfectly tempered climate on board the new Audi Q5 hybrid
quattro is optional equipment such as three-zone automatic air
conditioning and the panoramic glass roof. The latter comprises two
large half-sections of the roof. The front half slides back over the
rear half at the push of a button. A wind deflector keeps the level of
wind noise down to a minimum and the roller sunblind is also
power-adjusted.
Other comfort and convenience features of the
Audi Q5 hybrid quattro include cruise control, convenience key, garage
door opener, automatic anti-dazzle interior mirror, climate-controlled
cup holder, two different multifunction steering wheels - with optional
shift paddles - and three parking systems.
Sheer high-tech: the assistance and infotainment systems
The
assistance systems have a sheer high-tech character. These are the
parking system advanced with reversing camera, the lane departure
warning system Audi lane assist, and Audi side assist, which warns if it
is dangerous to change lanes.
The Audi Q5 hybrid quattro comes
with an unusually powerful system of components in the field of
communication and infotainment, sending it to the front of the pack in
the SUV segment. On the audio level, it begins with the Audi sound
system and extends up to the high-end sound system from Bang &
Olufsen. Features such as digital radio (DAB) reception and the Audi
music interface for full integration of an iPod complete the program.
The
Audi Q5 hybrid quattro also sets new standards for multimedia
performance. MMI navigation plus operates with a large hard drive and
two high-speed memory chips, and its large, high-resolution display can
show the landscape in the form of a topographical relief. Combined with
the Bluetooth online car phone, it brings the Internet to the car.
A
UMTS model sets up the connection to special services from Google and
the World Wide Web, bringing the latest news and weather information
into the vehicle.
Thanks to its generous level of standard
equipment and comprehensive range of options, the Audi Q5 hybrid quattro
offers everything required for an active lifestyle. It is highly
efficient, dynamic, spacious, multifunctional and comfortable. It will
be appearing in the fourth quarter of 2011.
