Now this is the kind of concept car that we like. BMW describes this as “..a High-performance concept study with BMW ActiveHybrid technology visualising the dynamic performance typical of a BMW against the backdrop of future demands in sustained mobility”. Perhaps more relevantly they also go on to say “..BMW Vision EfficientDynamics offers a realistic impression of the unique potential of BMW ActiveHybrid technology and the great innovative thrust of BMW EfficientDynamics.” Which in BMW-speak sounds like they intend to produce a car based on this concept model and employing their latest EfficientDynamics technologies. Nice.
Performance
The full hybrid 2+2 seater concept is powered by a three-cylinder turbodiesel combined with two electric motors. Overall power is 262 kW/356 hp with maximum torque of 800 Newton-metres/590 lb-ft. Power is delivered through an all-wheel drive transmission featuring an electric motor on both the front and rear axles.
There is one-electric motor positioned between the diesel engine and the double-clutch gearbox. It produces 25 kW (33-hp) and is able to reach a peak of up to 38 kW (51-hp) with a maximum torque of 214 lb-ft. The second electric-motor, which powers the front axle, offers a continuous output of 60 kW (80-hp), and peak torque of 162 lb-ft. Extra power of 84 kW (112-hp) is available for a period of up to 30 seconds and the electric motor is even capable of delivering 104 kW (139-hp) for 10 seconds. All of this is transmitted through a two-stage, single-speed reduced-ratio gearbox.
Performance is yet to be tested however it is predicted to reach 62mph from standstill in 4.8 seconds on its way to an electronically limited top speed of 155 mph. Fuel consumption equates to 75 mpg combined with CO2 emissions of just 99 grams/kilometre.
Electric power is generated without the slightest increase in fuel consumption from its diesel engine through a particularly efficient concept of Brake Energy Regeneration. Energy is stored in 98 lithium polymer cells from which the car is able to cover a distance of approximately 31 miles in the electric mode alone.
Design
BMW’s Vision is clothed in a lightweight body and unusually provides seating for four people, although rear seating is strictly for children. Gullwing doors open up to the side and use an innovative door mechanism to provide convenient and easy access for both front and rear occupants.
The roof and door inserts are made of polycarbonate glass which automatically darken in response to incoming sunlight.
What’s next?
BMW’s Vision EfficientDynamics concept will be displayed at next month’s Frankfurt Show, thereafter we will have to wait patiently to see in what form BMW intends to produce it.

Special Nonsense
September 1, 2009I like the look of this concept, very appealing. I think the tech seems spot on as well. Perhaps BMW is really goin to cash in on their current status as a progressive manufacturer by making cars that are not soley niche driven, but standard setting for technology, innovation and style.
Here’s hoping

September 1, 2009I second what special said. Hopefully this as well as the X6 and X1 which have already proved themselves, will carry on this innovative role..
