BMW Vision EfficientDynamics

New concept car - BMW Vision EfficientDynamics

The official world premier took place in Sept 2009 Frankfurt Motor Show. The new BMW Vision is a hybrid car that has 2 electric motors and a three-cylinder turbo-diesel engine. The total capacity is of 356 HP. The car can reach 100 km/h in only 4.8 seconds. And the best about this hybrid is the fuel consumption – no more than 3,76 liters for 100 km. Incredible! Love this car.More pictures after the jump.

The Exciting Look of EfficientDynamics
Like every concept car, this one makes your blood tingle and your lead-foot twitch. The blank-sheet approach to aerodynamics shows in every nook and cranny. In particular, the side view mirrors are set high and seem to flow from the car as if BMW left the body on the seashore in a brisk ocean breeze and allowed the wind to shape them. In profile, the car is set low to the ground and dominated by the shark-fin wheels, which appears as though they could cut through the air as a fish through water.

Fast and Fuel Efficient
The Vision EfficientDynamics Concept Car targets a top speed of 250km/hr (155mph), an important attribute in Germany, where all attempts to legally limit top highway speeds in the few remaining stretches of wide-open autobahn are continuously quashed. The 3 cylinder turbodiesel engine should sip only 3.7L/100km (almost 64 mpg) -- a completely achievable goal by a European car company, where a perfect storm of legal mandates and popular demand have long forced the automotive industry into leadership on fuel efficiency (at least, under official test conditions if not under M3 performance conditions). The two electric motors can be recharged by the engine as well as fully charged in about 2.5 hours plugged-in.
According to the BMW press release, the Vision promises:
Overall system output is 262 kW/356 hp, maximum torque 800 Newton-metres/590 lb-ft. All-wheel drive featuring an electric motor on both the front and rear axle.
Anticipated performance: Acceleration from a standstill to 100 km/h in 4.8 seconds, top speed 250 km/h (155 mph)
As a plug-in hybrid, BMW Vision EfficientDynamics is able to cover the entire fuel consumption drive cycle under electric power alone. Taking the sources of energy used for generating the electric power consumed into account (EU electricity mix), this reduces the CO2 emission rating to just 50 grams per kilometer.
Electric power is generated without the slightest increase in fuel consumption through a particularly efficient concept of Brake Energy Regeneration. Energy is stored in 98 lithium polymer cells.
Aerodynamics developed with know-how from Formula 1. CX drag coefficient optimised to just 0.22. Forward-looking energy management uses the maximum potential available in each case to minimise fuel consumption.
