SR 2 Corvette
Designed mid-1956 for Harlet Earl’s son Jerry, the SR-2 was put into racing duty in 1957. The car debuted at Daytona Beach in 1957 with a high-speed canopy, fender skirts and bullet-shaped frond headlights. Driven by Betty Skelton and Buck Baker, the car won the modified class with an average speed of 93.074 mph. The SR-2 also finished second in class for the flying mile with a top speed of 152.886 mph.
1959 Chevrolet Corvette CERV 1
The “CERV-1” (Chevrolet Engineering Research Vehicle) was developed as a research tool for that company’s continuous investigations into automotive ride and handling phenomena under the most realistic conditions. The car was built at the Chevrolet Engineering Center at Warren, Michigan in a special project headed by Mr. Zora Arkus-Duntov, Chevrolet Staff Engineer.
Corvette XP700 Concept
Designed and built under the personal supervision of Bill Mitchell, the wild-looking XP-700 used many regular Corvette components (frame, chassis parts and engine). Bill Mitchell had a lot of “customs” built for himself. This XP-700 previewed the new tail of the upcoming 1961 Corvette.
The Airbox option package designated RPO 579D came with the Duntov-cammed, Rochester fuel-injected 283/283 HP V-8. It incorporated a fiberglass intake plenum on the drivers-side inner fender. Fed by an opening in the radiator bulkhead, it channeled cooler, denser outside air through an internal filter and along a rubberized duct to the Rochester fuel-injection.
In 1956, Ed Cole, then General Manager of Chevrolet, decided Corvette could be saved from extinction due to lagging sales by promoting the car as a performance car which could be raced in production classes. The first of these Corvettes was to debut at Daytona Beach for acceleration and top end speed trials, the 12 hour race at Sebring, and also possibly Le Mans.
The engineers came up with a unit-body construction that relied on strength coming from the side sills of the chassis. These contained the exhaust which probably easily overheated the cockpit, especially in the coupe. Unfortunately, GM fitted fake V6 engines in both cars with a concept valve train that included dual overhead camshafts.
