Factory Five Racing GTM - a supercar at an accessible price
The idea for the GTM is simple. Design a modern supercar and price it where an ordinary guy can afford. The only catch is that you have to provide your own running gear (GM based) and you have to build it yourself.
"The price of the kit (launch price is $19990) is not as important as the price of the completed vehicle. Our original target was that a guy should be able to build the GTM for less than $30000. We think that is still achievable if a donor C5 is procured for less than current market value of $8000-$10000, and provided the person can do his/her own paintwork… but realistically we estimate that folks will spend between $35000 and $40000 to complete the car including Chevrolet parts, wheels/tires, paint and the Porsche transaxle."
After more than three years of engineering and development work, GTM is ready to introduce the world to their vision of what an American-designed Supercar should be.
The GTM is an American V-8 powered, mid-engined car with a composite body shell and an aluminum and steel tube frame chassis. The car uses GM Performance engine and suspension parts with four-corner coil-over shocks, huge brakes and a Porsche 911 Transaxle.
In the Factory Five tradition, the car is first and 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 C-5.
The car is engineered to be built as a chassis kit by a person at home. More than ten years of manufacturing the best engineered, safest, best selling and easiest to build kits in the world has made us uniquely capable of this challenge.
Lastly, no matter how well engineered the car is, and how good it looks, in order to succeed they knew they would have to ensure the car had modern comfort and control. The GTM has a large and quiet cockpit, good visibility and modern temperature controls. Items like A/C, power windows, and complete interior make sure the car isn’t limited to race track duty.
From the first design sketch to the completed production car the team has kept faithful to its charter to deliver a new All-American Supercar design. The GTM is 100% American designed and proudly made in the USA.
