"Ahead of the Frankfurt Motor Show starting 14 September, BMW has released the Vision EfficientDynamics Concept. This concept powered by a fuel-efficient 3-cylinder turbodiesel plug-in full-hybrid with one electric motor on each axle. It provides a top speed limited electronically to 155mph with acceleration 0-100 km/h(62mph) in 4.8 seconds. Average fuel consumption is 3.76 liters/100 kilometers.
Technology:
Offering a full-hybrid concept, the BMW Vision EfficientDynamics concept car is powered by a three-cylinder turbodiesel and two electric motors. 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) (electronically limited) , fuel consumption in the EU test cycle 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.
• 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."
