Engine and Performance
Early Models
The C4 Corvette debuted in 1984 with a 5.7L (350 cubic inch) V8 engine, producing 205 horsepower. This engine, known as the L83, featured Cross-Fire Injection, a precursor to modern fuel injection systems. The C4’s introduction also saw the return of a manual transmission option, with a 4+3 Doug Nash overdrive unit that provided a mix of performance and fuel efficiency.
Mid-Era Changes
In 1985, the L83 engine was replaced by the more advanced L98 5.7L V8, which initially produced 230 horsepower and was later upgraded to 250 horsepower. The addition of tuned port fuel injection (TPI) improved both performance and drivability. The introduction of the ZR-1 in 1990, equipped with a 5.7L LT5 DOHC V8 engine co-developed with Lotus, significantly boosted performance, offering an impressive 375 horsepower, later increased to 405 horsepower in 1993.
Late Models
The C4’s final years saw the introduction of the LT1 5.7L V8 engine in 1992, producing 300 horsepower. In 1996, the last year of the C4, the LT4 engine was introduced in the Grand Sport and Collector Edition models, offering 330 horsepower. These engines, combined with improvements in suspension and braking systems, solidified the C4’s reputation as a true performance car.
Design and Features
Exterior
The C4 Corvette’s design was a radical departure from the previous generation, with a focus on aerodynamics and a sleek, modern look. The body featured a clamshell hood that provided easy access to the engine and front suspension. Pop-up headlights and a distinctive wedge shape contributed to its futuristic appearance. The C4’s design was continually refined, with the addition of a more rounded rear end in the late 1980s and updated body panels in the 1990s.
