The new 2+2-seater hybrid-diesel BMW Vision Efficient Dynamics concept car, with sexy gullwing doors and low emissions, will be the centerpiece of the 2009 Frankfurt Motor Show, but there is plenty of information available about the car already.
Offering hybrid technology, the BMW Vision EfficientDynamics is powered by a three-cylinder turbodiesel and two electric motors. System output is 262kW (356hp), maximum torque is 800 Newton-metres (590 lb-ft). The all-wheel drive features an electric motor on both the front and rear axle.
With an anticipated acceleration from zero to 100 km/h in 4.8 seconds and top speed around 250 km/h (155 mph), fuel consumption in the EU test cycle of 3.76 litres/100 km (equal to 75.1 mph imperial gallons), and CO2 emissions are 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 through an efficient concept of Brake Energy Regeneration. Energy is stored in 98 lithium polymer cells. The car is able to cover a distance of approximately 50km (31 miles) in electric mode alone.
