Exterior appearance for 1992 was little changed. For the ZR-1, "ZR-1" emblems were added above the side fender vents. Two rectangular exhaust outlets were used for ZR-is and for standard models.

Instrument face plates and buttons were changed to all-black, replacing 1990-1991's grayblack. The digital speedometer was relocated above the fuel gauge. Gauge graphics were refined for better legibility.

The base engine for 1992 was the LT1, a new generation small block. In 1992 Corvettes, the engine developed 3OOhp (net) at 5000 rpm. Torque was 330 lb.-ft at 4000 rpm. Redline was 5700 rpm, 700 higher than the L98. There was an automatic fuel cutoff at 5800 rpm. Power increases were attributed to computer-controlled ignition timing, a low-restriction exhaust system employing two catalytic converters and two oxygen sensors (one converter and one oxygen sensor for each cylinder bank), higher compression ratio, new camshaft profile, free-flow cylinder heads, and a new multi-port fuel injection (MFI) system. At 452 pounds, the 1992 LT1 outweighed the 1991 L98 base engine by twenty-one pounds, due partly to replacement of stainless steel to exhaust manifolds with cast iron.

Corvette's new LT1 engine employed reverse flow cooling, a Chevrolet first. Rather than route coolant from the pump through the block to the heads, the LT1 routed coolant to the heads first. This permitted higher bore temperatures and reduced ring friction, and helped cooling around the valve seats and spark plug bosses.

Synthetic oil was recommended for the LT1. An engine oil cooler was no longer available, thought unnecessary when synthetic oil was used.

Traction control was introduced as standard equipment on all 1992 Corvette models. Called Acceleration Slip Regulation (ASR), Corvette's system was created by Bosch and developed in cooperation with Corvette engineers. It was engaged automatically with the ignition, but could be turned off by an instrument panel switch. Corvette's ASR used engine spark retard, throttle close down, and brake intervention to limit wheel spin when accelerating. When the system was on and active, the driver could feel a slight accelerator pedal pushback.

New Goodyear GS-C tires were introduced as standard equipment on all 1992 Corvettes and were exclusive to Corvettes worldwide for 1992. The GS-C tread design was directional and asymmetrical.

Improvements in weather sealing were achieved with improved weather strip seals. Road noise reduction came from additional insulation in doors and improved insulation over the transmission tunnel.

The power delay feature was modified so that the passenger door also cut power, in addition to the driver door or fifteen minute time period.

The 1-millionth Corvette, a 1992 white convertible, was built July 2, 1992.
