The Chevrolet Corvette is a sports car that was introduced in 1953. The C4 generation began in late 1983 for the 1984 odel year, after skipping the 1983 model year. It featured a much sleeker, more angular design than its predecessor. The C4 Corvette featured rear bumpers and body panels made of a sheet molding compound, a transverse fiberglass mono-leaf spring front suspension, a unibody construction, and a dashboard with digital LCD displays. Under the hood resided the naturally-aspirated OHV 5.7L Small Block L83 V8 engine (1984 model year only). Two transmissions were offered; they were the 4-speed 700R4 automatic and the 4-speed Doug Nash "4+3" manual with an automatic overdrive. All C4 Corvettes came with rear wheel drive. The naturally-aspirated OHV 5.7L Small Block L98 V8 became available in 1985. A convertible model, a high-mounted third brakelight, electronic climate control, and antilock brakes came in 1986. For the 1987 model year, the L98 was retuned to increase horsepower as external tuning house Callaway offered a twin-turbo kit through select dealers. In 1988, a 35th Anniversary edition and new wheels were introduced. The 4-speed manual was replaced by a ZF-sourced 6-speed manual transmission in 1989. The higher-performance ZR1 came in 1990. Developed with input from Lotus, the ZR1 featured the naturally-aspirated DOHC 5.7L LT5 V8 engine, the 6-speed ZF ML9 manual transmission, a convex rear fascia, leather seats, a Delco audio system, a Bilstein-tuned suspension setup (partially inspired by the Porsche 959), and ventilated disc brakes. 1991 would see a minor styling update. The naturally-aspirated pushrod OHV 5.7L LT1 V8 replaced the L98 for the 1992 model year. 1993 would see quite a few changes, including the addition of passive keyless entry, a 40th Anniversary Edition model, and retuned exhausts and cylinder heads for the ZR1. The C4 generation ended in 1996. It was superseded by the fifth-gen model (C5) for the 1997 model year. Seen at a Wal-Mart in Prescott, AZ.
