The cars from ‘I Robot’ are in town, and  I don’t know if Will Smith is driving them or not,  but in this reality they’re called ‘Vision EfficientDynamics’. That’s BMW’s concept that will debut at the Frankfurt Motor Show is a diesel-electric hybrid system with two electric engines and a small diesel motor.

The engine configuration is complex, with different engines allocating different amount of power to the front and rear wheels, with a total of 356 horsepower and 590 lb-ft of torque. Weighing just 3,075 lbs, it does 0 to 62 mph in 4.8 seconds, but its top speed is limited to 155 mph.

While the speed may be limited, BMW pulled all the stops when it came to fuel consumption – this concept gets 63 mpg and has a CO2 number below 100 g/km. These are not exactly common numbers for a BMW, but the company says it will become just that in the very near future.

As a pure electric car, it gets 31 miles before you have to switch on diesel, where a full 6.6 gallon tank gives you 400 miles. That’s if you don’t take into account the regenerative breaking, where the 181 inch long, 74 inch wide and 48 inch tall car uses the effect of its decelerating body mass to generate some juice for the batteries. Lithium-ion batteries which can store 10.8kW/h of electricity and output 364 Volts, all at a weight of 187 pounds.
