HTR Corvettes

GM has obviously done a great job in providing superior performance with the showroom stock Corvette. From the base 436 HP to the 505 HP ZO6 and the top dog ZR1 at 638 HP. The HTR lineup continues with the Corvette as we offer the following performance programs!

The HTR-GS Corvettes!

The following is a brief history behind the legendary Corvette Grand Sport! 

In early 1962, Corvette Chief Engineer Zora Arkus Duntov began top secret work on a Corvette purpose-built race car to win Sebring and Le Mans and more specifically — to put an end to the humiliating losses Chevrolet had suffered at the hands of Carrol Shelby and his Cobras.

 

The envisioned Grand Sport would be the ultimate Corvette, a lightweight, tremendously powerful factory built racer. Mounted with a 377cid small block with Weber side-draft carburetors, it dynoed at 550hp at 6400rpm and was designed to blow the hoods off Shelby’s Cobras. And if the Ferraris and Fort GT 40′s were also left in the dust, so much the better. 
After the prototypes had proven their mettle — and metal — 125 production street beasts were to be unleashed. But it never happened…  
 When they learned of Zora’s secret program, the Chevrolet boardroom put a stop to the car’s construction — but they couldn’t stop the five Grand Sports already built. And neither could the competition. From 1963 to 1967, the cars tore up the racetracks. And even after that, they continued to see duty and put up an excellent showing at races around the country and even overseas. This historic display of pushing the Corvette performance is what has inspired our modern day Grand Sport program through the Chevrolet dealership!
