What you're looking at above is the GYM Car concept designed by Coventry University design student Da Feng. As you might guess, its design incorporates exercise equipment that allows the driver to take his or her workout on the road. The GYM Car itself is a single-seater with a lightweight, injection-molded, magnesium alloy chassis and carbon fiber bodywork.
The GYM is powered by an electric motor with batteries that can be recharged by plugging it in or, and here's the interesting part, through the use of the onboard workout machinery. When the vehicle is parked, the driver can use any or all of the built-in equipment to generate electricity for the charge. There's a stepping machine and rowing machine available using the sliding seat, pedals and steering wheel. There's also a bench press or pull up simulator that uses the seat and an overhead handle. The arm rests can even be used for curls thanks to their tensioned resistance. Pretty much any move you make inside the GYM Car will burn calories and generate electrons at the same time.
