Bentley Builds an Electric Car

On the heels of a pretty dense seventeen-page document outlining Bentley Motors’ commitment to raising its fleet fuel economy and lowering carbon dioxide emissions comes tangible proof that someone at Crewe is working hard to turn the company’s green promises into green reality.
Bentley  Electric Car
A skunkworks team comprised of ten or so young apprentices at Bentley (six of whom are pictured after the break) gave up weekends and evenings to build the small wonder you see here: the supremely slick, battery-powered Continental DC electric car.


With a positively gorgeous carbon fiber composite body riding on a four-wheel single-wishbone fixed suspension and 1 x 16-inch Michelin low-rolling-resistance tires, the Continental DC (as in Direct Current) moves under the power of a 24-volt electric motor (from a motorized wheelchair, in fact) producing 0.5 horsepower and 5.1 pound-feet of torque and juiced by a pair of 12-volt batteries.

It looks like a Soap Box Derby racer, but don’t be fooled: The diminutive Conti DC (which tips the scales at 265 pounds, not including the driver) can hit a swift 40 mph under its own power, no hill required.


Naturally, the cockpit is trimmed in supple hide and Alcantara faux suede with contrasting diamond stitching. It is a Bentley, after all.

The Conti DC earned the Bentley team a special “Spirit of Greenpower” after running in the four-hour Greenpower Corporate Challenge at the venerable Goodwood racing circuit in Sussex, competing against cars from fifteen schools and nine other corporations.


From here, the littlest Bentley and the Greenpower Team is set to compete in the upcoming Formula 24+ season, which consists of eight 90-minute endurance races, the last one at Goodwood. The series is sort of an IROC for EVs, requiring all competing cars to use identical 24-volt electric motors powered by two 12-volt batteries. Racers must be between the ages of 16 and 24.
