The 1989 Chevrolet Corvette

1989 White Corvette Coupe

The 1989 Chevrolet Corvette introduced minor changes, the biggest being the introduction of the six-speed manual transmission manufactured by ZF (Zahnradfabrik Friedrichshafen). The new transmission senses the position of the throttle and only allowed shifts from first to second if the throttle was high. If the throttle was minimal it would block second gear and only allow a shift to fourth. This was one of the ways that were used to get fuel economy higher. Also the standard wheel and tire this year was the P275/40ZR17 tire and 17" wheel setup that had been part of the Z51 and Z52 packages in 1988. The Z52 option was no longer available. A new "Selective Ride and Handling System" (RPO FX3) was only available with the manua transmissions and cars equipped with the RPO Z51 "Performance Handling" package. The SRC system offered three modes of driving: Tour, Sport and Performance. The low tire warning system that had intially been slated for 1987 was redesigned and was finally available as RPO UJ6 after being redesigned. A new simpler folding top for the convertibles was introduced as well as newly designed seats. A fiberglass auxillary top was available for the convertible for the first time since 1975. The sport seats were only available in cars optioned with Z51 because of weight and fuel economy concerns. 84 Corvette ZR-1 "King of the Hill" cars were built for evaluation and media preview although the car was delayed until the 1990 model year. Planning was also started this year on the new "C5" which was intended to be a 1993 model. Budgetary and GM executive decisions delayed the introduction of the C5 until 1998.
