Not totally relying on the turbodiesel engine, the Vision EfficientDynamics also features a plug-in solution where the batteries can be recharged in 2.5 hours when connected to a 220-volt 16-amp outlet. With a 380-volt 32-amp electric source, the charging time can be as little as 44 minutes. Running in full electric mode, the car can travel up to 31 miles. With only the turbodiesel providing power, an approximate 400-mile range can be obtained using a 6.6-gallon tank.



In the European Union test cycle, aided by the car's aerodynamic shape (its drag coefficient is just 0.22) and narrow tires for a sports car — 195/55s on 21-in. wheels—the Vision is able to achieve a fuel economy rating of 3.76 liters/100 kilometers (62.5 mpg equivalent), with CO2 emission recorded at a low 99 g/km.



Due to the car's considerable power and relatively low curb weight of 3076 lb., BMW claims the Vision EfficientDynamics concept can hit 100 km/h (62 mph) in 4.8 seconds, and easily exceed its electronically limited top speed of 155 mph.
