Is the C4 Corvette plastic or fiberglass?
The C4 Corvette, produced from 1984 to 1996, had a body made of fiberglass, not plastic. Fiberglass was the primary material used for the Corvette's body panels and structure during this generation of the iconic American sports car.
Fiberglass Construction of the C4 Corvette
The C4 Corvette was designed with a fiberglass-reinforced plastic (FRP) body, which was a common material choice for sports cars at the time. Fiberglass offered several advantages over traditional steel construction, including lower weight, better corrosion resistance, and easier shaping of the aerodynamic body panels.
The use of fiberglass allowed Chevrolet's engineers to create the sleek, curvaceous styling that defined the C4 Corvette's appearance. The fiberglass body panels were molded and bonded to a steel frame, providing a sturdy yet lightweight structure.
Benefits of Fiberglass over Plastic
While both fiberglass and plastic are composite materials, there are some key differences that made fiberglass the better choice for the C4 Corvette's body:
- Strength: Fiberglass is generally stronger and more durable than plastic, making it better suited for the demands of a high-performance sports car.
- Flexibility: Fiberglass can be molded into complex shapes more easily than plastic, allowing for the Corvette's distinctive aerodynamic design.
- Repairability: Fiberglass body panels can be more easily repaired in the event of damage, compared to plastic which is more prone to cracking and breaking.
These advantages made fiberglass the material of choice for the C4 Corvette's body, providing the perfect balance of strength, styling, and repairability for this iconic American sports car.
What year did Corvette stop using fiberglass?
The Corvette hasn't been an actual fiberglass car since 1973. From GM Media: Starting with the third generation in 1968, the body parts were manufactured with a press mold process, whereby the fiberglass material and resin were shaped in a die-like tool that produced smoother parts more quickly.
What is the C4 Corvette frame made of?
steel
The C4's perimeter frame was built from 18 pieces of stamped and boxed high-strength steel that included the tall side sills, the front sides, the rear sides, four crossmembers and braces. All of the pieces were positioned in a jig and welded together.
Were C4 Corvettes fiberglass?
It was the work of a team under chief Corvette designer Dave McLellan, who'd taken over from Duntov in 1975 — under the design direction of Irv Rybicki. In a departure from the fiberglass panels of its forebears, the C4's rear bumpers and panels used a sheet molding compound.

The bumpers and rocker panels are made of urethane and the side fender gills are plastic. As for the acronym, I guess you mean C4. It was given the C4 brand not many years ago. It stands for the 4th generation Corvette.
