First Complete Redesign Since 1963 The Chevrolet Corvette C4, introduced in 1984, was the first complete redesign of the Corvette since the C2, featuring a brand-new chassis, sleeker aerodynamics, and a modernized design.
Digital Dashboard Innovation The C4 was the first Corvette to feature a fully digital dashboard, with futuristic-looking LCD displays for speed, RPM, fuel level, and other essential gauges.
Focus on Handling Over Raw Power While early C4 models had modest power (205 hp in 1984), they prioritized improved handling, thanks to a completely new suspension design and a lower center of gravity.
The First Corvette to Reach 1G Lateral Acceleration Thanks to its advanced suspension and wide tires, the C4 Corvette became the first American production car capable of achieving 1G of lateral acceleration, making it a true cornering machine.
Return of the ZR-1 Supercar Killer In 1990, Chevrolet introduced the ZR-1 version, featuring a 5.7L DOHC LT5 V8 (developed with Lotus), producing 375 hp (later increased to 405 hp in 1993), making it one of the fastest cars of its time.
Pioneering the Targa Top Design The C4 was the first Corvette to feature a standard removable Targa roof, offering a balance between coupe and convertible driving experiences.
Controversial Clamshell Hood The C4 introduced a unique clamshell-style hood, which opened from the rear and exposed the entire engine bay, making maintenance easier but requiring precise alignment when closed.
The Corvette That Skipped a Year Production delays caused Chevrolet to completely skip the 1983 model year, making the C4 officially debut as a 1984 model, with only one 1983 Corvette prototype surviving.
Special Edition Grand Sport in 1996 The 1996 Corvette Grand Sport was a limited-edition farewell to the C4 generation, featuring a 330-hp LT4 engine, Admiral Blue paint with a white racing stripe, and red fender hash marks.
Influence on Future Corvette Models The C4 laid the groundwork for modern Corvettes by introducing key innovations like lightweight materials, advanced suspension tuning, and aerodynamic efficiency, paving the way for the C5 and later models.

The C4 Corvette is America’s last analog sports car—a pop-up-headlight, fiberglass-bodied icon that’s finally gaining respect. In Europe, clean LHD examples are rare but still affordable, with prices now rising for low-mileage, unmodified cars.
