The 1982 and 1984 Corvette engines had "Cross Fire Injection", but genuine fuel injection returned to the Corvette in 1985 for the first time in two decades. The 1985 tuned-port injection, built by Bosch, was standard equipment and featured a mass airflow sensor. Aluminum-tube tuned intake runners, a mold-cast plenum, and an air cleaner mounted forward of the radiator support. This new L98 engine delivered a horsepower increase from 2OShp to 230hp, a torque increase from 290 lb.-ft to 330, and a real-world fuel economy increase of about 11%.

The overdrive selection switch for 4-speed manual transmissions was moved during 1985 production from the console to the gear shift knob.

Suspension rates were lowered in 1985, a result of harsh ride criticism. Springs for the base suspension were softer by 26% in front, 25% in the rear. Springs fro RPO Z51 were 16% softer in front and 25% softer in the rear. To compensate for the spring change, larger-diameter stabilizer bars were included with Z51 equipped models.

In its January 1985 "ten best" issue, Car and Driver magazine pronounced the Corvette to be America's fastest production car at an even 150mph top speed. Corvette also took top honors in top-gear acceleration and tied for best (with Porsche) in road holding as measured by 0-force skid-pad adhesion.

The bore of the brake master cylinder was increased in 1985, and the booster itself was plastic, the first such application in an American Car. The new plastic booster was 30% lighter and less subject to corrosion.

Manual transmission 1985s came with a new, heavy-duty 8.5-inch ring differential. Rear axle gearing for manuals was 3.07:1, Standard gearing for automatic transmission was 2.73:1, but the 3.07:1 could be ordered as RPO 092. Wheel balance weights changed in 1985 from the outside-rim, clip-on style, to an inner-surface adhesive type. The changer was mainly for aesthetics, but Chevrolet also believed a better balance resulted because of the adhesive weight's proximity to the wheel's depth center.

A full length oil pan gasket reinforcement was added tot he 1985 Corvette engine to improve gasket compression seal.

Electronic instrumentation continued much as the previous year, but displays were revised and improved with cleaner graphics, less color on the speedometer and tachometer, and larger digits for the center-cluster liquid crystal displays.

A map strap was added to the 1985's drive-side sun visor.
