Classic Car Archive Specs, Facts, & History
The Chevrolet Corvette (C4) was a sports car produced by the Chevrolet division of General Motors for the 1984 through 1996 model years.
The editors of Consumer Guide stated: "The first fully redesigned Corvette in 15 years was more sophisticated and more practical than the beloved Shark.”
The 1993 Corvette followed the progression of C4 Corvettes with improved torque, handling, keyless entry, and high-performance options that made it a slick and fun ride.
Chevy’s “King of the Hill” ZR-1 and its LT5 were appropriately beefed up for the 1993 Corvette. Modifications to the valve train and cylinder heads along with the use of platinum-tipped spark plugs and synthetic oil enabled the engine to produce 405 hp (up from 375 hp), while a new exhaust gas recirculation system also improved emissions control.
Not to be ignored, the standard LT1 engine gained 10 pounds/foot of torque, now up to 340 pounds/foot, and ran more smoothly and quietly, thanks to a host of internal improvements.
To aid handling, base models followed the ZR-1’s lead by adopting different width tires at the front and rear. The front tires were narrowed slightly to 255/45ZR17 and their rims slimmed by one inch, to 8.5 inches. The rear tires were widened slightly, to 285/40ZR17, on the same 9.5-inch wheels as before.
A newly optional passive keyless entry system that was unique to the Corvette as it automatically locked or unlocked the doors as the driver left or approached the car. The proximity-based system engaged or disengaged when a specially encoded key fob sensor entered or left a magnetic field that surrounded the vehicle. In addition to unlocking the doors when in range, the system would also turn on the interior lights and disengage the alarm system, and it could be programmed to unlock either just the driver’s door or the passenger’s as well.
The Corvette reached yet another milestone in 1993 and another special edition was offered. The 40th Anniversary Edition, RPO Z25, cost $1,455 and included Ruby Red paint, matching leather seats and wheel centers, and special badges; it was ordered on 6,749 cars. In addition, all cars equipped with leather seats came with 40th Anniversary embroidery on the headrests, while standard black cloth seats remained unadorned.
Despite the LT5 engine, ZR-1 sales remained at a mere trickle, with only 448 produced for 1993. Overall, however, Corvette sales rose for the first time in four years, to a final tally of 21,590 units.
