1992 CHEVROLET CORVETTE
The One-Millionth Corvette, rolling off the assembly line on July 2, 1992 and went right into the National Corvette Museum. The new 5.7-liter LT1 replaced the 5.7 TPI engine, boosting output from 245 to 300 horses. Acceleration Slip Regulation (ASR), one of the earliest electronic traction control systems on a production car, that used a combination of retarding the spark, controlling the throttle opening, and applying the brakes to maintain traction. Thankfully, the was a defeat switch just above the headlight switch, for those who loved smokey burnouts.

The interior on the 1992 Chevrolet Corvette was largely carried over from prior years. The car pictured here has the premium leather sport seats, an $1,100 option. Overall, weatherstripping and insulation made the cabin quieter and drier. The power delay feature that powers accessories for a delayed period after the ignition was switched off until a door is opened, added the passenger door.

While the 375-horse DOHC ZR-1 might have been stealing the headlines, big news was brewing in the engine room of the standard ’92 Corvette. Gone was the old Gen-2 small block TPI engine. Replacing it was the first major reengineering of the small block V8. The differences between Gen-1 (pre-1986) and Gen-2s (1987-1991) were minor compared to the total rethinking that went into the new LT1. The entire cooling system was “reversed”, now sending coolant to the heads first, then to the block, thereby allowing hotter, leaner mixtures, by keeping the combustion chambers cooler. More cooling passages were also cast in around the spark plugs and valve seats. In addition, the LT1 included freer-flowing heads, 10.3:1 compression (made possible by the added cooling), computer controlled ignition timing, an all new multi-port electronic fuel injection system, a freer-flowing exhaust system and two oxygen sensors. This all combined to make 300 horsepower and 330 pound-feet, and at only a 20-pound weight penalty over the engine it replaced.
