The one-millionth Corvette was produced on July 2, 1992.
The LT1 was also the first Chevrolet powerplant to use "reverse flow cooling," in which the engine routed coolant directly to the cylinder heads, rather than sending it through the block first. This was said to allow higher bore temperatures and reduced ring friction, and also help cooling at key points. Mobil 1 synthetic oil was now used at the factory and was recommended for subsequent changes; the use of synthetic oil precluded the need for an engine-oil cooler, which was no longer offered as an option.
could be expected, the motoring press greeted the new standard engine with
gusto. Perhaps what Chevrolet did not expect was that most reviewers would also
conclude that the LT1 and its 300 bhp tended to make the ZR-1 with its 75 extra
horsepower -- not to mention its steep sticker price -- somewhat irrelevant. Car and Driver, for example, found that
while the ZR-1 could hit 60 mph from a standing start in 4.7 seconds, the LT1
could reach it in just 5.1 seconds. While the magazine's top speed of 179 mph
for the King of the Hill still reigned supreme, few rational motorists could
argue that the 161 mph top-end the LT1 reached wasn't enough. On paper and in
buyers' minds, the extra $31,683 tariff for the ZR-1's dwindling performance
premium hardly seemed worth it, and only a scant 502 buyers ordered RPO ZR1.
All 1992 Corvettes benefited from a new standard traction-control system called Acceleration Slip Regulation, which was developed in conjunction with Germany's Bosch. It used the ABS sensors to detect rear-wheel slip and apply the brakes to the affected wheels and/or throttle back power to maintain traction. A dashboard switch could be activated to disable the system. Further helping the car hug the road to match the LT1 powerplant's added muscle were standard new directional/asymmetrical-tread Goodyear GS-C tires.
physical changes were nominal at best for '92. The car's twin exhaust outlets
were now rectangular in shape, and the ZR-1 acquired additional identifying
emblems on its side fenders.
