Four years ago, we visited a small, tucked-away warehouse in Rockville where Genovations Cars founder Andrew Saul was building an electronic car using Corvettes and Fords as test beds. Now he’s just weeks away from completing the prototype.

The all-electric Corvette—called the Genovation Extreme Electronic or GXE (above)—will be finished by the end of this month, followed by three weeks of testing. The GXE is based on a 2006 Z06 Corvette; Andrew says it will produce over 700 horsepower and 600 lb-ft of torque, go 0-60 mph in around three seconds and have top speeds of 200 mph. He adds that most of the parts are designed and built in America. (Yes, but will it finally convince Millennials that they should have cars?)

After testing, the car heads to various raceways with the goal of setting lap records for a street legal electric car, says Andrew (above). The speed record is currently 177 mph. The building team included electric engineering experts from MIT and a mechanical engineer from Cosworth with experience in designing and building record-breaking electric vehicles. It will be on display in Michigan in mid-September at the Electric Vehicle Technology Expo—a big deal trade show in the electric vehicle engineering world.
