While we've never found Mercedes Benz's smart line of cars appealing, we like what we see with this futuristic new concept vehicle. The smart forspeed Electric Roadster will never see production (sigh!) but a number of its design elements and underlying technologies will. The smart forspeed accelerates from 0 to 60 km/h in just 5.5 seconds and reaches a top speed of 120 km/h. A 30 kW magneto-electric motor is installed at the rear of the smart forspeed and the vehicle concept provides an immediate powerful response from stationary. They should put a few of these in an upcoming Transformers movie.
