The GTM is a V-8 powered, mid-engined car with a composite body shell and an aluminum and steel tube frame chassis. The car uses a GM Performance engine and suspension parts with four-corner coil-over shocks, large brakes and a Porsche 911 Transaxle and is foremost a high performance car. The GTM is light and aerodynamic, with excellent weight distribution and precise race-car handling/braking derived from the Chevrolet Corvette C5. In the September 2007 issue, Car and Driver reviewed a prototype GTM LS7 and their testing achieved 0-60 mph in 3.0 seconds and 1/4 mile in 10.9 seconds at 134 mph, beating their tested speeds for the Ferrari 599 GTB Fiorano, Porsche Carrera GT, Lamborghini Murcielago, Ferrari Enzo and other higher priced production vehicles. The testing shows the GTM is designed to compete with the fastest accelerating cars in the world.

The car is engineered to be built as a chassis kit by a person at home. Items like A/C, power windows, and complete interior make the vehicle suitable for general use.

The GTM chassis is also used as a prototype and testbed for the Capstone CMT-380 vehicle, a hybrid gas turbine/electric sportscar with potentially 500 mile range.
