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 Corvette for 1991 received a smoother, slimmer nose with wraparound parking/cornering/fog lights, wider body side moldings that were now body colored, and horizontal front-fender strakes that replaced the previous gill-like louvers.
They also got the rear end look from the 1990 ZR-1 including the rectangular tail lights. The base wheels were changed to a new saw-blade design. The new RPO Z07 included the Z51 suspension components and the FX3 adjustable ride options, this provided an in-cockpit adjustable ride from stiff to very stiff.
Inside, a new power-delay feature allowed the audio system and power windows to operate after the ignition key was switched off until the driver's door was opened, up to a maximum of 15 minutes. In addition, a "low oil" indicator was added to the driver information center, and all models were pre-wired to accommodate a cellular telephone or other 12-volt accessory. On ZR-1s, the "full power" indicator light was relocated to alongside the valet-selection key.
Effectively combining the previous Z51 performance handling package with the FX3 selective ride and handling option was the new RPO Z07. At $2,155, the new package included all heavy-duty suspension components to offer a choice between a "firm" and "very firm" ride; previously, if the Z51 and FX3 were combined some standard suspension components were retained, allowing a choice between a "soft" and "firm" ride. Limited to coupes only, the Z07 package was intended for enthusiasts and racers.
Exhaust systems were also revised for '91, and included larger muffler sections with a more finely tuned exhaust note and lower back pressure; though this was intended to boost performance, power ratings for the L98 engine remained the same as before.
And for 1991, the ZR-1 retained unique doors and rear fenders to accommodate its 11-inch-wide rear wheels and tires. This left only the slightly wider rear flanks, a roof-mounted center stop-lamp (other models now integrated it into the rear fascia) and a single badge to distinguish a ZR-1 from a base coupe.
The World Challenge racing series would continue for 1991, though Chevrolet would no longer build specially modified Corvettes to run in the series; all performance modifications were now the responsibilities of the individual race teams.
Sales for the 1991 model year followed the ZR-1's downward trend, and declined to 20,639 units, with coupes outselling convertibles by about a three-to-one ratio.
