Debuting at the North American International Auto Show in  Detroit next month will be an electric version of BMW’s small four-seat coupe, Concept ActiveE.

The Bavarian company known for its performance sedans says the coupe is capable of  acceleration from zero-to-100 km/h (62 mph) in less than 9 seconds, with a maximum speed of about 145 km/h (90 mph, electronically limited.

The motor, specially developed for the model and located in the rear axle, delivers 125 kW  or 170 horsepower and provides maximum torque of 250 Nm or 184 lb-ft.

The real-world range world range of the EV is expected to be about 160 km (100 miles) on a single charge, depending on your weather conditions, and your lead foot. (Well, maybe it should be “lithium foot” these days.)

The FTP 72 cycle range (Federal Test Procedure)  is calculated to be 240 km (150 miles) in simulation, according to BMW. The cycle, which is stop and go, favors an electric vehicle since simulates an urban route of 7.5 miles with frequent stops. The maximum speed is 56.7 mph and the average speed is 19.6 mph – not exactly autobahn usage  figures.

It was the use of numbers derived like these that caused the hybrid mileage controversy when real results turned out much lower. Honda recently settled a class-action suit over such a matter. BMW is to be commended for its honest, data-based approach here.
