History

Fourth Generation cars intruduced: Camaro and Firebird Coupe, Z28, Formula and Trans Am. Z28 selected as Indy 500 Pace Car, and came with special black/white paint and decals, all were automatics (though rumors of one 6-speed car, built for a GM exec, still persist). Two engines were available: The L32 3.4 V6 in the Coupes, and the LT1 5.7 V8 in the Z28, Formula and Trans Am, rated at 275 hp.

The Camaro Coupe came with steel wheels and wheel covers, with optional alloys, while the Z28 had them standard. Instrumentation had yellow lettering, while the window and climate controls were gray.

The base tires were the Eagle GA with an S speed-rating. Any cars with these tires included a 105 mph speed limiter. The base coupes only came with the GA, but the V8 cars could be ordered with the Eagle GS-C (QLC) Z-rated high performance tire, which did away with the speed limiter entirely.

The Firebird had standard alloys that were different from the twisty-type on the Formula and Trans Am. Very few 1993 cars were made with T-Tops.

Exterior colors available: Arctic White, Bright Red, Black, Bright Teal, Polo Green, Dark Gray-Green Metallic, Purple Pearl Metallic, Medium Patriot Red, Medium Quasar Blue, Yellow (Only 196 made, Pontiac only).

Interior colors were Light Gray, Graphite and Tan. Cloth only.

Trans Am and Trans Am GT models differentiated by raised spoiler on GT model.

25th Anniversary Trans Am came in white with single blue center stripe, white 5-spoke wheels and a white leather interior.

Instrumentation was changed in the Camaros to white, and the window and climate controls became black.

The T56 6-speed transmission was revised with new gear ratios and also introduced CAGS, the skip-shift feature. The only axle ratio available with the 6-speed was now a 3.42.

The 4L60 transmission was replaced by the 4L60-E electronic unit.

Exterior colors: Yellow (Only 304 made, Pontiac only) dropped at midyear.

Interior colors were Light Gray, Graphite, Tan, and Flame Red (Cloth only).

Leather interior introduced late in the year, in graphite or tan.

Trans Am GT merged back into Trans Am, and raised spoiler now an option.

The L36 3.8 V6 was introduced midyear, and was only available in California. V8 cars in California received dual catalytic converters, good for an additional 10 hp. Base Eagle GA tires were upgraded from S-rated to T-rated, and therefore the speed limiter that was included on cars with these tires was raised from 105 mph to 115 mph.

The Eagle RSA (QFZ) all-season Z-rated tire was introduced and available on the V8 cars, in addition to the Eagle GS-C (QLC) high-performance Z-rated tire.
