HISTORICAL NOTES

  • 35.1% of 1972 Corvettes had power windows
  • 88.2% had power steering
  • 63% had air conditioning
  • 48.1% had tilt steering
  • 6% had a close-ratio four-speed manual transmission
  • 7% had a heavy-duty four-speed manual transmission
  • 6.4% (1336) had the LT1 engine
  • A 1972 Corvette with the base ZQ3 V-8 could do 0-to-30 mph in 3.1 seconds, 0-60 mph in 8.5 seconds and the quarter mile in 15.2 seconds at 83 mph.
  • A 1972 Corvette with the LT1 V-8 could do 0-to-30 mph in 2.9 seconds, 0-60 mph in 6.9 seconds and the quarter mile in 14.3 seconds at 92 mph.
  • A 1972 Corvette with the LS5 V-8 could do 0-to-30 mph in 3.8 seconds, 0-60 mph in 6.8 seconds and the quarter mile in 14.1 seconds at 93 mph.
  • Even though the horsepower rating were lower (e.g., the 1971 LT1 was rated at 330 hp, but the 1972 LT1 was rated at 255 hp), the performance was the same. In 1971 and previous years, the horsepower rating was a gross figure calculated before adding any equipment (alternator, pumps, fans, etc.). But across the industry (not just GM), the ratings were calculated on a net figure. Many people incorrectly attributed the decrease to pollution equipment and the use of unleaded gasoline.
