1993

Corvette entered its fourth decade and to mark the occasion a 40th Anniversary edition was offered featuring an exclusive Ruby Red metallic exterior and leather sports seats; special wheel center trim, and emblems in the same special color.

Aside from the special anniversary edition, leather seats in all 1993 Corvettes carried a 40th Anniversary emblem on the headrest. Beyond that, exterior styling was virtually unchanged from the 1992 model.

Under the hood, however, changes did take place. The ZR-1 option made the Corvette arguably America's most powerful automobile when its engine the LT5, received a power boost from 375 to 405 horses. Modifications to the cylinder heads and valvetrain; platinum-tipped spark plugs, and the exclusive use of synthetic oil were among the upgrade that brought this about. In addition, an electrical, linear exhaust gas recirculation system improved emissions control.

The small block LT1 engine, reintroduced the preceding year, also underwent changes. While its rating remained the same at 300 horsepower, the engine was made more quiet.. The heat shield was changed from a single-piece stamping to a sandwich-type that was self-damping; magnesium covers were replaced with thermoset polyester valve covers, and the camshaft exhaust lobe profile was modified to help increase torque.

The 1993 was General Motors' first product to feature a passive keyless entry (PKE) system. A battery-operated transmitter locked and unlocked doors when the driver approached or departed the vehicle.

Front wheels and tires on all basic cars were reduced in size, while rear wheels and tires were enlarged. For the special adjustable suspension performance package, front and rear wheels and tires sizes were identical.

1993 witnessed an uptick in production with 15,898 coupes and 5,692 convertibles manufactured. Of the 21,590 produced, over 6,700 were 40th Anniversary specials and 448 were ZR-1s.

Prices increased moderately with the basic coupe up $960 to $34,595; the convertible $1,050 more at $41,195; the 40th Anniversary package added $1,455 to the sticker price, and the ZR-1 option remained priced at $31,683.
