On of the Frankfurt Auto Show’s best kept secrets has now been fully revealed. The new Vision EfficientDynamics Concet is a mean-looking 2+2 sports car that uses both a turbo-diesel three-cylinder engine as well as two electric motors in a full plug-in hybrid layout. BMW says the goal of the project was to build a vehicle that has the performance of one of its M cars, while delivering fuel-economy that is superior to current small cars. This they most certainly achieved with a 0-62 mph time of 4.8 seconds and a claimed fuel economy figure of 62.6 mpg.
The diesel engine used is essentially half of that found in the current BMW 335d, displacing 1.5-liters. On its own the diesel makes 163hp and 214 ft-lbs of torque. The car also gets BMW’s impressive six-speed dual-clutch transmission.
Two electric motors are paired to this engine, which is located in a mid-rear configuration. A 33hp motors sits between the engine and transmission while a second 80-hp motor delivers power to the front axle. The result it a total of 356hp and 590 ft-lbs of torque. Storing that energy is a lithium-polymer battery pack that runs down the center of the car for optimum weight distribution.
BMW says the Vision EfficientDynamics Concept can be plugging in a charged at a conventional outlet in just 2.5 hours and can travel up to 31 miles on pure electric power. A 6.6 gallon diesel tank will then allow an extended range of 400 miles.
