  • The ZR-1 was again powered by the 32-valve DOHC 5.7-liter V-8 matched with a six-speed transaxle.
  • Corvette models used the aforementioned more powerful 5.7-liter V-8 fitted with the four-speed overdrive automatic or optional six-speed manual transmission.
  • Both models had new rectangular exhausts.
  • A new all-black dash treatment, relocated digital speedometer and improved instrument graphics were adopted.

HISTORICAL NOTES

1992 Corvette Notes

  • Model-year production: 20,479.
  • Calendar-year sales: 19,819.
  • The 1,000,000th Corvette was produced on July 2,1992.
  • It was a 1992 Corvette convertible and was posed for a factory publicity photograph alongside a first-year 1953 Corvette.
  • With the introduction of the base LT1 V-8, the introduction of an Acceleration Slip Regulation (ASR) traction-control system as standard equipment and the standard use of Goodyear Eagle GS-C high-performance tires with directional and asymmetrical tread design, Chevrolet Motor Division could advertise that "The all-around performance of the Corvette has been raised to the highest point in the car's 39-year history."
  • Eight major factors contributed to the increased power of the LT1 engine:
    1. A reverse-flow cooling system
    2. Computer-controlled ignition timing
    3. A low-restriction exhaust system incorporating a two-piece converter and exhaust-runner assembly for easier service access
    4. The use of high-compression-ratio pistons
    5. The use of a new camshaft profile
    6. The use of new free-flowing cylinder heads
    7. The use of four-bolt main bearing caps on the three center bearings
    8. The use of new synthetic SW-30 engine oil (also eliminating the need for a separate engineoil cooler).
  • An LT1-powered Corvette with automatic transmission was tested for 0-to-60 mph in 5.26 seconds and did the quarter mile in 13.9 seconds at 102.2 mph.
  • An LT1-powered Corvette with the six-speed manual transmission was tested for 0-to-60 mph in 4.92 seconds and did the quarter mile in 13.7 seconds at 103.5 mph.
  • A 1992 Corvette ZR-1 with standard manual transmission was tested for 0-to-60 mph in 4.3 seconds and did the quarter mile in 12.9 seconds.
  • This proved that the LT1 engine had dramatically narrowed the performance gap between the base Corvette and the much more expensive ZR-1 Corvette.
  • On August 28, 1992, Chevrolet Motor Division announced that David McLellan would be retiring as Corvette chief engineer.
  • McLellan had taken over the Corvette program after the retirement of Zora Arkus-Duntov in 1975.
  • Chevy's assistant manager of public relations Tom Hoxie said in 1992, "During McLellan's 18-year tenure he transformed the Corvette from an American muscle car into an internationally-acclaimed, high-performance sports car that runs rings around a host of more expensive European and Japanese models."
  • Said McLellan, "I can't think of a better time for me to be leaving.
  • No manufacturer has ever built one million sports cars and at the age of 40 the Corvette is stronger than it's ever been.
  • Our all-new car is a few years old and it's time to let someone else put their stamp on it."
