Dream Car Giveaway




Most of the Corvette publicity this year centered on the eagerly-awaited ZR-1 which was claimed to be the world's fastest production automobile.

  • After several announcements proved premature, the ZR-1's introduction was delayed until the 1990 model year.
  • Meanwhile, the "ordinary" Corvette added a new ZF six-speed manual gearbox with two overdrive ratios.
  • To meet fuel-economy standards, the ingenious transmission was designed with a computer that sent a signal to prevent shifts from first to second gear unless the gas pedal hit the floor.
  • Instead, a blocking pin forced the shifter directly into fourth gear for improved fuel economy during light-throttle operation.
  • Joining the option list was a new FX3 Delco-Bilstein Selective Ride Control system with a switch to select the desired degree of shock absorber damping for touring, sport, or competition driving.
  • Only hatchbacks with a manual transmission and the Z51 Performance Handling package could get the ride-control option.
  • For the first time since 1975, a removable fiberglass hardtop became available for the convertible, but not until late in the model year.
  • Corvette colors were
    • White
    • Medium Blue Metallic
    • Dark Blue Metallic
    • Black
    • Dark Red Metallic
    • Bright Red
    • Gray Metallic
    • Charcoal Metallic
  • Chevrolet also painted 33 cars in two non-standard colors.
  • Six were done in Yellow and 27 were done in Arctic Pearl.
  • Interior trims came in Blue; Black; Gray; Red; Saddle; and White.
  • A removable body-color roof panel for hatchbacks or body-color convertible top were standard, along with cloth upholstery.


  • The serial number [Vehicle Identification Number -- VIN] was stamped on a plate on the inner vertical surface of the left windshield pillar visible through the windshield.
  • The Coupe serial numbers ranged from 1G1YY218*K5100001 to 1G1YY218*K5126328
  • The Convertible serial numbers ranged from 1G1YY318*K5100001 to 1G1YY318*K5126328
