New Vision EfficientDynamics BMW Concept Car

Vision EfficientDynamics BMW Concept Car

BMW released today the official details and photos of the Vision EfficientDynamics Concept, a “new revolutionary concept car with BMW EfficientDynamics technology.”
The new concept uses a a three-cylinder turbodiesel and two electric motors and the total 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. The sprint from 0 to 100 km/h is made in just 4.8 seconds while the top speed achieved is limited at 250 km/h (155 mph). Fuel consumption is impressive: 3.76 litres/100 km (equal to 75.1 mph imp), CO2 emissions 99 grams/kilometre.
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 kilometre. 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. The car is able to cover a distance of approximately 50 km/31 miles in the electric mode alone. The impressive performances are also available due to the drag coefficient optimised to just 0.22.
