2011 BMW i8 Concept



The BMW i8 Concept and the fascinating approach that underpins it embody the vision of a sustainable contemporary sports car brought to life. Its innovative plug-in hybrid concept combines the modified electric drive system from the BMW i3 Concept - fitted over its front axle - with a high-performance three-cylinder combustion engine producing 164 kW (220 hp)/300 Nm (221 lb-ft) at the rear. The electric motor in the BMW i8 Concept is a full-capability unit which can also power the car on its own, if required. However, working in tandem allows the two drive systems to display their respective talents to the full, delivering the performance of a sports car but the fuel consumption of a small car.

Acceleration of 0 to 100 km/h (62 mph) in under five seconds combined with fuel consumption in the European cycle of under three litres per 100 kilometres (approx. 94 mpg imp) and average customer fuel consumption of between five and seven litres per 100 kilometres (40.4 - 56.5 mpg imp) - even when driven hard - are figures currently beyond the capability of any vehicle powered by a combustion engine of comparable performance. Thanks to its large lithium-ion battery, which can be charged from a domestic power supply, the BMW i8 Concept can travel up to 35 kilometres (approx. 20 miles) on electric power alone. A large proportion of short everyday journeys can therefore be completed with zero emissions. The car's electric-only mode allows it to enter emissions-capped central areas of cities with access restrictions in place for petrol or diesel-powered vehicles. The i8 Concept's efficiency rating is further enhanced by its ability to generate energy at both axles. The electric motor at the front axle recoups maximum energy every time the driver brakes, while a high-voltage alternator hooked up to the combustion engine charges the battery, if required. Added to which, the 2+2-seater offers enough space for four people, giving it a high level of everyday practicality.

The emotional design of the BMW i8 Concept ensures its qualities are clear for all to see. Its dynamic proportions give the BMW i8 Concept the appearance of surging forward before it even turns a wheel and lend visual form to its extraordinary performance. The sophisticated concept behind the upward-swivelling doors fixed to the A-pillars underlines the car's sporting capability and opens up access to the front and rear seats at the same time.

A series of air inlets allow the air to flow through and around the vehicle to optimum effect, ensuring extremely low drag. They also add visual emphasis to these advanced aerodynamics. Airflow plays an extremely important role at the rear of the vehicle as well. Intakes behind the passenger cell and at the rear provide a cooling flow of air through the engine compartment, while outlets in the rear diffuser and the flow of air around the rear wheels ensure the car is extremely efficient in terms of lift and downforce at both axles.

The LifeDrive architecture of the BMW i8 Concept has been carefully adapted to enhance the vehicle's sports car character, and therefore to deliver unbeatable performance and excellent driving dynamics. The motor in the front axle module and combustion engine at the rear are connected by an "energy tunnel", which houses the high-voltage battery. This gives the car a low centre of gravity - and the dynamic benefits that come with it. The positioning of the electric motor and engine over their respective axles and the space-saving and well-balanced packaging of all components result in an optimum 50/50 weight distribution.

The weight of every component inside the BMW i8 Concept has been minimised down to the very last detail, allowing the extra weight of the electric drive system and battery to be cancelled out. The BMW i8 Concept therefore presents the ideal environment in which to sample this very special drive concept on the road. The passengers sit - in typical sports car style - in an extremely low and enclosed position inside the CFRP-constructed Life module (mounted above the Drive module).

The sporting character of the BMW i8 Concept continues into the interior. Boasting a driver-focused environment unmatched by any BMW Group vehicle before it, the BMW i8 Concept immerses the driver fully in the unique driving experience. The purpose-built driver's position is geared squarely towards the person at the wheel and gives optimum access to all information and controls. The three-dimensional displays are crystal clear and flash up the relevant information for the driving situation at hand. The interior as a whole is defined by the functionality of a classical BMW sports car and majors on lightness and ease of use. The BMW i8 Concept is the sports car for a new generation - pure, emotional and sustainable.

2011 BMW X5




2011 BMW X5 will write the latest chapter in the story of the world's first Sports Activity Vehicle® in the spring of 2010. Originally launched for the 2000 model year in late 1999, the BMW X5 permanently changed the automotive landscape. It proved that the driving dynamics, responsiveness, and linear control signature to every BMW could be compatible with utility, versatility, and other-roads capability. For 2011, the BMW X5 models are enhanced with new powertrains and updated design. The new BMW X5 will make its North American debut at the 2010 New York International Auto Show.

Innovative new design elements and powertrains are the result of over 4,000 new parts created by BMW designers and engineers for the 2011 BMW X5. Two of the X5's powertrains will be all-new for 2011, creating the new BMW X5 xDrive50i and BMW X5 xDrive35i, in addition to the familiar BMW Advanced Diesel X5 xDrive35d. All models receive a design update that enhances the brilliant focus and aesthetic appearance of the X5 brand.

Fresh Design. Well-Balanced Proportions.
The body design of the 2011 BMW X5 is characterized by well-balanced proportions that accentuate the vehicle's powerful presence and agility. A long wheelbase, short front and rear body overhangs, and large light-alloy wheels provide a visual balance between the front and rear of the vehicle. Square-shaped, carefully flared wheel arches hint at the BMW X5's all-wheel drive traction and other-roads capability. The body lines sweep upwards from the front and rear wheels, communicating BMW's near-perfect 50-50 front-rear weight distribution which is so essential to the BMW X5's legendary driving dynamic.

The sides of the BMW X5 are elegantly stretched though the strong horizontal lines of each side. The surface of the hood flows seamlessly into the waiseline, while the prominent, gently inclined contour line at the door handle level extends from the front wheel arches to the rear of the vehicle. These character lines symbolize power, stability, and presence.

With its distinctively contoured hood, large BMW kidney grille and dual round headlights, the new BMW X5 boasts an expressive front end that symbolizes power and presence. The newest interpretation of the BMW X5's look is led by the redesign of the front fascia and position of the standard foglamps. Due to an increase in the number of elements painted body color, the front end gives the impression of being lower. At the same time, the increased size of both the central and outer air intakes hint at the boosted engine output. The black trim at the bottom edge of the body is now considerably narrower. A matte-finished silver protection plate extends across the entire width of the central air intake, emphasizing the muscular features of the SAV, and accentuates the new BMW X5's character.

The dual round Xenon Adaptive headlights and foglamps are now situated higher and closer to the kidney grille. The BMW X5's new headlight fixtures emphasize high quality and sporting intentions. BMW's signature corona rings serve as position lights and daytime driving lights.

The newly conceived rear apron matches the graphic structure of the front end, while the intricately designed surrounds of the dual exhaust pipes are painted in body color to underline the BMW X5's premium character. In the center, a matte-finished silver protection element emphasizes strength and durability suitable for other-roads use.

Above the rear bumper, the rear of the new X5 is divided by parallel horizontal lines. The result is an accentuation of the width, highlighting the vehicle's athletic capabilities. The L-shaped taillight fixtures, each with two LED light banks, create the BMW-signature nighttime appearance of the rear end.

A choice of new body colors provides further visual enhancements. The metallic colors Deep Sea Blue, Platinum Grey, and Sparkling Bronze are now available for the BMW X5. Inside, the available Nevada Leather can be chosen in stunning new Oyster or Cinnamon Brown colors in addition to the familiar Sand Beige, and Black, and matte Satin Silver interior trim strips are added if the owner does not select from the available Brushed Aluminum, Dark Bamboo, Light Poplar, or Burl Walnut wood trims.

BMW X5 xDrive50i: BMW's Twin-Turbocharged V-8.
The new BMW X5 xDrive50i takes its place as the flagship of the X5 family, yielding 400 horsepower at 5,500 rpm and 450 lb-ft of torque at 1,750 - 4,500 rpm from its twin-turbocharged 4.4 liter V-8 engine. Introduced in the BMW X6 in Spring of 2008, this all-aluminum V-8 features High Precision direct fuel injection, "reverse-flow" architecture for revolutionary responsiveness and packaging, and BMW' s VANOS variable valve timing technology. Together, these features create what may be the perfect balance between high fuel efficiency, low emissions, and the dominant, dynamic performance expected of a BMW V-8. The 0-60 mph sprint is accomplished in 5.3 seconds.

BMW X5 xDrive50i starts at $59,275 including Destination & Handling.
As part of the V-8 engine's reverse-flow architecture, the twin turbochargers are situated in the valley of the engine's "V" and exhale separately into two catalytic converters which are located on top of the engine and exit aftward into the large stainless-steel exhaust system via downpipes on either side of the new 8-speed automatic transmission. The exhaust streams remain separated until they meet in the large muffler at the rear of the vehicle and exit through two large, trapezoidal exhaust tips.

BMW X5 xDrive35i: BMW's Turbocharged Inline-6 with Valvetronic.
BMW X5 xDrive 35i receives a brand new inline-6 gasoline engine, internally dubbed "N55." The new engine features the same 3.0-liter displacement and 300 horsepower output of its predecessor (the "N54"), but features a single twin-scroll turbocharger in place of the previous twin, low-mass turbocharger units. Furthermore, the new inline-6 of the BMW X5 xDrive35i is the first BMW inline-6 to combine BMW's revolutionary Valvetronic throttle-less intake technology, High Precision direct fuel injection, and turbocharging. The result of combining this new inline-6 with the new 8-speed automatic is an BMW X5 with incredibly spontaneous responsiveness, exceptional power, and remarkable efficiency. The new BMW X5 xDrive35i will perform the 0-60mph sprint in 6.4 seconds, coincidentally on the same pace as the outgoing V-8 powered BMW X5 xDrive48i.

For the 2011 model year, BMW has made the X5 xDrive35i available in two additional trim levels: "Premium" and "Sports Activity."

The essential BMW X5 xDrive35i has an MSRP of $46,675 including Destination & Handling, and includes a popular profile of standard equipment often specified by BMW X5 customers, including BMW's Xenon Adaptive headlights, Rain Sensor with automatic headlight control, HD Radio, automatic climate control, foglights, 18" light alloy wheels, cruise control, and anti-theft alarm system. A Convenience Package is optional and adds the large panoramic moonroof, auto-dimming mirrors, Dark Burl Walnut, Bamboo, or Light Poplar wood interior trim, BMW Ambiance Lighting, and BMW Assist with Bluetooth. Stand alone options include rear side window shades, Navigation system with Real Time Traffic Information and Voice Command, satellite radio with 1-year subscription, and an iPod / USB adapter interface.

The BMW X5 xDrive35i Premium has an MSRP of $52,475 including Destination & Handling and includes a boosted profile of standard equipment, such as 19" light alloy wheels, roof rails and panoramic moonroof, power adjustable steering column, iPod / USB adapter interface, and privacy glass. Best of all, it includes standard Nevada Leather. In addition, buyers of the Premium model may choose up to four packages, including the Active Ventilated Seat Package, Convenience Package, Cold Weather Package, and Technology Package. Each package includes a raft of focused features that enhance comfort and convenience, allowing buyers to better customize the BMW X5 to personal taste. Third Row seating, which enables the BMW X5 to accommodate up to 7 passengers, also becomes available on this model.

The BMW X5 xDrive35i Sport Activity has an MSRP of $54,975 including Destination & Handling and includes even more standard equipment than the Premium model, such as 20" light alloy wheels, sport seats, Shadowline exterior trim, and Anthracite headliner. In addition to the packages available on the Premium model, customers may add the popular M Sport Package to the BMW X5 xDrive35i Sport Activity model. The M Sport Package includes 20" wheels with performance tires, the Adaptive Drive system, aluminum roof rails, M door sill plates, M driver footrest, M steering wheel, M aerodynamic enhancements, and increased top speed limiter (150 mph).

New 8-speed Automatic Transmission with Steptronic.
On both new gasoline models of the BMW X5, sending the newfound power to the standard xDrive intelligent all-wheel drive system is BMW's new 8-speed automatic transmission with Steptronic control. The new 8-speed transmission is standard in the BMW X5 xDrive50i and X5 xDrive35i, and raises the industry standard for compactness, efficiency, and gear selection. The new transmission weighs no more than its 6-speed predecessor, yet offers closer ratios in the lower gears for improved acceleration and two additional "tall" gears for relaxed, efficient cruising. BMW's 8-speed automatic was introduced on the 5-Series Gran Turismo and 760Li Sedan in the fall of 2009.

Using the console-mounted e-shifter, the BMW X5 driver chooses from three shifting programs: Drive, Drive Sport, and Manual. In Manual mode, the driver selects from the eight forward gear ratios via the + / - action of the shifter (push forward to downshift; pull back to upshift). At any speed, Neutral is easily selected via a forward push of the selector from Drive and, when at a standstill, Park is selected by depressing the "P" button atop the shifter, or by pushing the Engine Start-Stop button (doing so will also stop the engine).

BMW's Brake Energy Regeneration system is also fitted to the gasoline X5 models. It incorporates a special deep-cycle Glass Mat battery with programmed alternator disengagement so that, most of the time, the vehicle's battery is only charged while the vehicle is coasting or braking. Over time, the Brake Energy Regeneration system can save 1-2% on fuel consumption. Brake Energy Regeneration is another feature in BMW's EfficientDynamics portfolio of small features and adjustments which have a cumulative effect on the efficiency-performance balance of each BMW vehicle.

BMW X5 xDrive35d: Maintaining the Benchmark with BMW Advanced Diesel Technology.
The BMW Advanced Diesel X5 xDrive35d was introduced to the United States as a 2009 model, and despite increased competition remains the fastest, most fuel efficient diesel-powered vehicle in its class. The huge torque output of 425 lb-ft. at 1750-2250 rpm speaks for itself; BMW X5 xDrive35d drivers will marvel at this engine's robust response at low to medium speeds. The peak power output of 265 hp also makes an impact, as does the resulting 0-60-mph time of 6.9 seconds. It returns EPA mileage estimates of 19 mpg city and 26 highway.

For the 2011 model, BMW has made no changes to the award-winning BMW Advanced Diesel powertrain, but rather has focused efforts to ensure the BMW X5 xDrive35d benefits from the latest design updates to the X5 family. Despite the enhancements for the new model year, MSRP for this model remains $52,175 including Destination & Handling.

BMW Advanced Diesel with BluePerformance optimizes emission management by incorporating an oxidation catalyst placed close to the engine, a diesel particulate filter housed in the same unit, and an SCR catalyst with urea injection. Apart from filtering out even the smallest particles from the flow of exhaust gases, this combination ensures effective reduction of nitric oxides (NOX) by way of a chemical reaction within the exhaust system initiated by the injection of a small dose of urea referred to as Diesel Exhaust Fluid. Into the exhaust stream. The ammonia (NH3) generated in this process within the SCR catalyst subsequently converts the nitric oxides (NO and, respectively, NO2) in the exhaust gas into environmentally compatible nitrogen (N2) and water vapor (H2O).

BMW has developed a two-tank system for DEF ensuring convenient use of this new technology with all the benefits and ease required by the customer: The amount of DEF required in each case is drawn from the active tank comprising approximately 1.6 gallons by means of a dosage pump. And since the urea solution would freeze at a temperature of 12.2o F (-11oC), this active tank, as well as the dosage pipes are heated.

2011 BMW i3 Concept




 


The BMW i3 Concept is an uncompromisingly sustainable vehicle designed for urban areas. Driven purely by electric power and purpose-built to meet the demands of sustainable and emission-free mobility, it embodies an intelligent form of urban transportation and commuting.

"This automotive concept uses a new architecture which showcases all of its new possibilities and potential. It is the world's first premium electric vehicle." - Andreas Feist, Head of vehicle project BMW i3.

The BMW i3 is a well-resolved all-round concept, with every detail conceived and optimised to fulfil its eventual purpose. Central to its design is the innovative LifeDrive architecture, the key to the BMW i3 Concept's appeal as a light, safe and spacious car. Innovative use of materials and intelligent lightweight design not only enable the i3 Concept to travel long distances on a single charge and provide superb safety in the event of a collision, they also help give the car its excellent driving dynamics. The secure arrangement of the battery in the Drive module gives the vehicle a very low centre of gravity and optimum weight distribution. The electric motor over the rear axle - which generates output of 125 kW/170 hp and impressive torque of 250 Nm (184 lb-ft) from a standstill - and a small turning circle combine to deliver pleasingly crisp driving characteristics and give the driver a very immediate experience of the BMW i3 Concept's lightweight design. The BMW i3 Concept accelerates from 0 to 60 km/h (37 mph) in under four seconds and from rest to 100 km/h (62 mph) in less than eight seconds. The extremely direct sensation at the wheel is expressed in outstanding agility at low speeds and during turning manoeuvres, and makes parking in tricky situations that much easier.

The Life module conjures up a feeling of space inside the car more generous than even the latest conversion vehicles can offer. Select materials lend the open and airy cabin a lounge-like character. The use of renewable raw materials is another defining characteristic of the interior, offering passengers a further means of "experiencing" the sustainability of the vehicle. Elements of the instrument panel and door panelling are visibly made from natural fibres, while the naturally tanned leather of the seats creates a lounge-style ambience. Together, these materials provide an appealing contrast to the clear, "floating" forms of the instrument panel and door elements, and lend the interior a strikingly modern feel. With the drive components located in the Drive module, there is no centre tunnel running through the passenger compartment. This allows the two front and two rear seats to be connected with each other by a continuous seat surface, which allows for ease of entry and exit via the front passenger side of the car and means you can park up close to walls, for example. With four seats, wide-opening opposing "coach" doors, boot capacity of around 200 litres and an additional functional compartment in the front, the BMW i3 Concept is neatly equipped for the demands of everyday use.

However, the electric motor developed by BMW and the optimised lightweight design of the LifeDrive architecture cannot take all the credit for imbuing the car with such efficiency and enabling it to travel such long distances on each charge. Indeed, the ability of the car to recoup energy while on the move and special range-extending functions, such as ECO PRO mode, also add miles to the clock. With ECO PRO mode activated, all the vehicle functions operate with maximum efficiency. For example, the accelerator mapping is tweaked to limit the output summoned when the driver flexes his right foot, and the climate control functions also use as little energy as possible. Added to which, sophisticated aerodynamics and slim, low rolling resistance wheels minimise resistance to the car's forward progress and maximise its range.

Innovative connectivity functions create a seamless connection between the BMW i3 Concept and its customers' lives outside the car. Remote functions accessible via a smartphone enable owners to find their vehicles, flag up nearby charging stations, allow battery charging and preconditioning at the touch of a button and supply information on the current status of the vehicle. Meanwhile, intelligent assistance systems ease the stress on drivers in monotonous city driving situations and allow them to arrive at their destination more safely and in a more relaxed state of mind.
