The 1992 Corvette LT1 was “the first all-weather Corvette” (Road and Track). Acceleration Slip Regulation (ASR), or traction control, was introduced as standard equipment. Developed by Bosch, the system was adapted for the Corvette by GM engineers, and although it was engaged at ignition, the ASR system could be disabled with the push of a button above the headlight controls. The system worked to limit wheel spin and managed power output when it sensed low traction. The driver could feel additional resistance in the accelerator pedal when the system reduced throttle. Coupled with the exclusive for Corvette Goodyear GS-C tire, the ‘92 Corvette was perfectly driveable in dreary weather, while its exotic competition remained in their garages.
Also new for ‘92 was the LT1 engine, which produced 300 hp and 330 lb.-ft of torque. Chevrolet changed its cooling system on the LT1, and used reverse-flow cooling. This unique system cooled the heads before sending coolant to the block, which made it possible for the engine to sustain higher bore temperatures and reduced ring friction. This, coupled with the use of synthetic Mobil 1 oil, which didn’t heat as quickly as traditional oil, helped the engine operate more efficiently, without a separate oil cooler.
1992 marked another milestone for the Corvette. On July 2, 1992, GM produced its one millionth Corvette: a white convertible with red interior and a black soft-top, just like the first one from 1953. GM donated this milestone Corvette to the National Corvette Museum in Bowling Green, KY. It was one of eight cars swallowed by the massive sinkhole in early 2014. GM plans to restore the car to its original condition.
