Two details marked the 1985 Corvette as being different from its newly-restyled 1984 predecessor.

  • The first detail was a new Tuned Port Injection nameplate on fender molding and the second was the straight tailpipes at the rear.
  • That nameplate identified a new 350-cid (5.7-liter) V-8 under the hood.
  • It had a tuned-port-fuel-injection (TPI) system and 230 hp.
  • City fuel economy ratings went up.
  • Otherwise, the only evident change was a slight strengthening in the intensity of the Red and Silver body colors.
  • The Corvette's smoothly-sloped nose, adorned by nothing other than a circular emblem, held retracting halogen headlamps.
  • Wide parking and signal lamps nearly filled the space between license plate and outer body edge.
  • Wide horizontal side marker lenses were just ahead of the front wheels.
  • The large air cleaner of 1982 was replaced by an elongated plenum chamber with eight curved aluminum runners.
  • Mounted ahead of the radiator, it ducted incoming air into the plenum through a Bosch hot-wire mass-airflow sensor.
  • Those tuned runners were meant to boost power at low to medium rpms, following a principle similar to that used for the tall intake stacks in racing engines.
  • Electronic Spark Control (ESC) sensed knocking and adjusted timing to fit fuel octane.
  • Under the chassis, the 1985 Corvette carried a reworked suspension (both standard and optional Z51) to soften the ride without losing control.
  • The Z5l handling package now included 9.5-inch wheels all around, along with Delco-Bilstein gas-charged shock absorbers and a heavy-duty cooling system.
  • The stabilizer bars in the Z51 package were thicker.
  • Spring rates on both suspensions were reduced.
  • Cast aluminum wheels held P255/50VR-16 Eagle GT tires.
  • Brake master cylinders used a new large-capacity plastic booster.
  • Manual gearboxes drove rear axles with 8.5-inch ring gears.
  • The Corvette's instrument-cluster graphics had a bolder look and its root panels added more solar screening.
  • An optional leather-trimmed sport seat arrived at midyear.
  • Corvette standard equipment included
    • an electronic information center
    • air conditioning
    • limited-slip differential
    • power four-wheel disc brakes
    • power steering
    • cornering lamps

    • power windows
    • a trip odometer
    • a theft-deterrent system with starter interrupt
    • a compact spare tire
    • dual electric remote-control sport mirrors
    • tinted glass.
  • Black belt, windshield, and body side moldings, plus color-keyed rocker panel moldings protected the bodies.

1985 Corvette Notes

  • Chevrolet claimed a 17 percent reduction in 0-60 mph times with the TPI power plant.
  • To save weight, Corvettes used not only the fiberglass leaf springs front and rear, but over 400 pounds of aluminum parts (including steering, suspension components and frame members).
  • A total of 14,802 Corvettes had the Z51 performance handling package installed, 9,333 had Delco-Bilstein shocks were ordered separately and only 9,576 had a four-speed manual transmission.
  • Only 16 Corvettes are listed as having a CB radio, and only 82 were sold with an economy rear axle ratio.
