Chevrolet Engineering Research Vehicle

The primary function of the "CERV-1", was to provide Chevrolet engineers with a test platform from which direct visual studies were made from all types of ride and handling behavior under amplified conditions.

By such means, suspension phenomena that are extremely subtle, and thus difficult to isolate within the performance capabilities of a regular passenger car, may be studied and treated quantitatively with the "CERV-1".

Some broad features of the "CERV-I" are: extremely light weight to afford a horsepower-to-weight ratio such as that usually associated with high performance aircraft; rear mounted engine in unit with a fully synchronized four-speed transaxle; the only passenger, the driver, sits well forward on the centerline of the car for virtually optimum visibility, and all four wheels are independently suspended to provide a high order of stability and positive handling.

The chassis is an extremely stiff frame of chrome-molybdenum steel tubes welded into a truss-like structure weighing approximately 125 pounds (57 kg).

The lightweight body (approximately 80 pounds (36 kg)) is aerodynamically styled and fully encloses the underside of the car.

Such specific output, only one pound per horsepower, is rarely achieved in reciprocating engines, even in the most highly developed aircraft types.

A special fuel injection unit has ram tubes of larger cross section and 2510 longer than those of the regular production design.

Power from the engine is transmitted in a conventional manner through the lightweight flywheel, clutch, and Corvette type four-speed transmission.

Attaching directly to the rear end of the transmission case is the differential and final drive gear mechanism.

Power transmission to the wheels is completed through individual axle shafts with universal joints on each end, or a total of four in-all.

Hot Rod's road test of the prototype with Turbo Hydramatic, stock Vega differential, and street tires yielded quarter mile (~400 m) times under 14 seconds.

A third link runs from each rear wheel hub forward to the frame to transmit driving and braking thrust.

Variable rate coil springs unitized with direct, double-acting shock absorbers are diagonally mounted at each rear wheel.

Adjustment provisions in the rear suspension linkage permit variations in camber and toe-in to facilitate engineering studies.

To achieve superior performance, the car was built on a monocoque chassis, powered by a 377 ci all-aluminum SOHC V8 with Hilborn injection rated at 500 hp (370 kW).

The car's mid-mounted V-8 is a 5.7-liter 32-valve, dual-overhead cam LT5, with twin turbos and internal modifications, giving it 650 hp (485 kW), 655 lb⋅ft (888 N⋅m)- torque, and a top speed of 225 mph (362 km/h).

Other standard features include computer-controlled active suspension system, ABS braking and traction control, six-speed automatic transmission, all-wheel-drive and four-wheel steering along with a fully multiplexed electrical architecture.

It was unveiled by Corvette chief engineer Dave Hill on 1993-5-3 at the General Motors Technical Center in Warren.
