The 1993 Chevrolet Camaro was the first of the fourth-generation Camaros. The fourth generation ceased production in 2002. Following an eight-year hiatus, Chevy revived the Camaro, which better reflected the first-generation styling. Chevy carried over many of the mechanical components from the third-generation Camaro, but improved its front suspension and gave the Z28 model a hefty 5.7-liter V-8 that brought back some of the muscle lost in the second- and third-generation Camaros.
The 1993 Z28 model offered real muscle by using the Corvette's 5.7-liter (350-cubic-inch) LT1 small-block V-8. The LT was Chevy's transitional Generation II engine, featuring aluminum heads and a reverse-flow cooling system that cooled the heads before the block. The LT1 can trace its lineage to the original 1955 small-block V-8s. It was Chevy's most powerful V-8 since the original (and hyphenated) LT-1, debuted in 1970. Chevrolet slightly detuned the Z28's version of the LT1. The 1992 Corvette's LT1 generated 300 horsepower and 340 foot-pounds of torque. The 1993 Z28 version wielded 275 horsepower and 325 foot-pounds of torque. The 1996 and 1997 Camaros saw a boost to 285 horsepower and 335 foot-pounds of torque. A four-speed automatic or six-speed manual transmission complemented the engine. The rear final drive ratio was 3.42-to-1.
Body and Chassis
The body of the 1993 Z28 Camaro was new, with sheet metal- and plastic-flared fenders. The sleek, almost bullet-like appearance was more faithful to the first generation Camaros. The frame was remarkably similar to the third generation models. The floor stamping and rear suspension were nearly identical, but the front suspension sported a short-arm/long-arm suspension system and rack-and-pinion steering. The wheelbase remained the same at 101.1 inches, but the body's length grew by about an inch, to 193.2 inches. Stopping power came from all-wheel 10.5-inch ventilated disc anti-lock brakes. The car sat on 16-inch wheels and its curbside weight was 3,466 pounds.
The Z28 is a true performance car, achieving zero to 60 mph in 6.3 seconds and the quarter-mile in 14.8 seconds at 97 mph. "Motor Trend" magazine tested the Z28 in June 1993 and clocked it reaching 60 mph in 5.8 seconds and completing the quarter-mile in 14.4 seconds, at 97.9 mph. In August 1994, "Car Craft" magazine road-tested the Z28 equipped with a 414-horsepower Paxton supercharged LT1. It hit the quarter-mile in 13.1 seconds at 111.8 mph. "Motor Trend" also tested the Paxton supercharged Z28 in December 1994, and it achieved the quarter-mile in 13.2 seconds at 111 mph.
Callaway Cars, an aftermarket performance builder, developed the high-performance 1993 Camaro Z28 Callaway. The builder installed a 6.2-liter (383-cubic-inch) SuperNatural V-8 engine that produced 404 horsepower and 412 foot-pounds of torque. A six-speed manual transmission transmitted the power. "Motor Trend" tested the car in March 1994 and it reached 60 mph in 4.6 seconds and completed the quarter-mile in 13.2 seconds, at 106.4 mph. "Car and Driver" magazine conducted its speed tests in March 1997 and clocked the Callaway as reaching 60 in 5.1 seconds and completing the quarter mile in 13.3 seconds, at 109 mph.
