The 1991 Chevrolet Corvette Convertible (C4, facelift 1990) measures approximately 4,432 mm (174.5 inches) in length, 1,770 mm (69.7 inches) in width, and 1,258 mm (49.5 inches) in height. These dimensions reflect the car's aerodynamic sports car proportions, providing a sleek profile that balances length and width to ensure agility and stability on the road. The relatively low height further enhances its sporty stance and helps with the vehicle's center of gravity, improving handling.

The curb weight of the 1991 Corvette Convertible (C4, facelift 1990) is around 1,590 kg (3,505 pounds). This weight is moderate for a sports car from this era, balancing the structural demands of the convertible with performance needs. A curb weight in this range allows the car to accelerate swiftly and handle responsively without excessive fuel consumption. The weight also affects braking distances and tire wear but overall helps the Corvette maintain its reputation as a high-performance sports car capable of spirited driving.

The wheelbase of the 1991 Corvette Convertible (C4, facelift 1990) is approximately 2,540 mm (100 inches). Wheelbase is the distance between the front and rear axles and plays a crucial role in vehicle stability, ride comfort, and handling dynamics. A 2,540 mm wheelbase provides a good balance, giving the Corvette stable cornering ability and a smooth ride. Longer wheelbases tend to increase stability at high speeds but may reduce maneuverability, so the Corvette's wheelbase supports its sporty, responsive driving characteristics.

Interior space in the 1991 Corvette Convertible is designed for two passengers, with a snug cockpit that emphasizes driver engagement. Passenger room is compact but comfortable for a sports car, with headroom and legroom optimized for performance seating. Cargo capacity is limited due to the convertible design, offering about 143 liters (5 cubic feet) behind the seats — enough for small luggage or groceries but not larger items. The focus is clearly on performance and driver experience rather than spaciousness or practicality.

Yes, the 1991 Corvette Convertible is generally suitable for parking inside a standard residential garage. Most standard garages accommodate vehicles up to about 2,440 mm (8 feet) wide and 5,000 mm (16.4 feet) long. With the Corvette's dimensions of approximately 4,432 mm (174.5 inches) in length and 1,770 mm (69.7 inches) in width, it fits comfortably within these limits. However, owners should consider the garage door opening height and interior clearances for the convertible top, especially if it is parked with the roof up.

Compared to the previous C3 generation Corvette Convertible (produced until 1982), the 1991 C4 Corvette Convertible is slightly more compact overall but features a more modern, aerodynamic design. The C3 was longer, about 4,570 mm (180 inches) in length, and wider, at nearly 1,900 mm (74.8 inches). The C4 generation refined the car's proportions, reducing overall size to improve performance and handling. This resulted in a lighter, shorter, and narrower car that feels more agile and responsive on the road while maintaining the iconic Corvette character.

In comparison to similar sports cars of the early 1990s, such as the Porsche 911 Cabriolet and the Mazda RX-7 convertible, the 1991 Corvette Convertible is competitively sized. For example, the Porsche 911 Cabriolet is slightly shorter in length but narrower, while the Mazda RX-7 is smaller overall. The Corvette's broader width and longer wheelbase provide enhanced stability and a more spacious cockpit. This balance of dimensions helped position the Corvette as a serious American contender in the sports car market against well-established European and Japanese rivals.

The 1990 facelift for the C4 Corvette Convertible introduced minor but notable changes in exterior styling while the fundamental dimensions remained largely consistent with earlier C4 models. The length, width, and height did not significantly change — the car remained approximately 4,432 mm (174.5 inches) long, 1,770 mm (69.7 inches) wide, and 1,258 mm (49.5 inches) tall. However, aerodynamic tweaks improved drag and stability. Upgraded exterior features like remodeled bumpers, revised headlights, and updated trims enhanced the car's aesthetics and performance rather than its size.

The 1991 Corvette Convertible's dimensions are engineered to optimize performance driving. Its low height of approximately 1,258 mm (49.5 inches) reduces aerodynamic drag and improves center of gravity for better cornering. The width at 1,770 mm (69.7 inches) provides a stable footprint enhancing grip and road holding. A moderate length of 4,432 mm (174.5 inches) combined with a 2,540 mm (100 inches) wheelbase balances agility with stability. These dimensional characteristics work together to deliver the hallmark sharp steering response, confident handling, and open-air sports car experience.

Beyond dimensions, the 1990 facelift of the C4 Corvette Convertible brought updates in styling, performance, and features. The exterior saw revised bumpers, new composite headlamps replacing pop-ups, and refined aerodynamics that contributed to a sleeker look and enhanced high-speed stability. The engine options received slight tuning improvements, boosting power output and efficiency. Interior refinements were made for increased comfort and ergonomics, including updated materials and instrumentation. These improvements collectively modernized the C4 while maintaining its iconic American sports car identity.
