Although the C4 had already proven itself throughout the second half of the nineteen-eighties, there was no question that the Corvette would be transformed forever with the arrival of the 1990 model year. Although the automotive world was focused on the arrival of the ZR-1, all Corvettes built-in 1990 received some minor improvements. The interior of the Corvette received some minor improvements as well. A newly revised instrument display was introduced in the 1990 Corvette. The new display now combined a digital speedometer with an analog tachometer, fuel gauge, oil pressure gauge, battery gauge, (and others).
The L98 engine received a slight increase in power, boosting engine performance to 245 horsepower, thanks to the addition of an added air-intake speed density control system, a revised camshaft and an increased engine compression ratio.
