The Chevrolet Corvette was first introduced in 1953 – making it one of the earliest American sports cars. The initial production model – referred to as the C1 – was a stylish convertible that came with a six-cylinder engine. As time passed, the Corvette continued to evolve, sporting larger engines and increasingly aggressive designs.

The second generation Corvette, known as the C2, was produced from 1963 to 1967 and was a significant milestone in the vehicle’s history. The C2, also known as the ‘Sting Ray’, was renowned for its curvaceous and striking design and introduced the legendary 427 cubic-inch V8 engine. The C2 Corvette is widely recognised as one of the most beautiful and iconic American cars ever created.

Subsequent generations of the Corvette – including the C3, C4 and others – continued to evolve and improve in terms of performance, technology and design. The Chevrolet Racing Team consistently participated in various racing series and achieved significant success with the Corvette.


The Birth of Greenwood IMSA

John Greenwood, an American race car driver, and team owner, shared a profound love for the Chevrolet Corvette. In the 1970s, he became renowned for his racing team, Greenwood Racing, and his exploits in the International Motor Sports Association (IMSA) racing series.

Greenwood had a vision of pushing the boundaries of what the Corvette could achieve on the racetrack. He collaborated with Chevrolet in the mid-1970s to create the Chevrolet Corvette Greenwood IMSA, a highly modified version of the Corvette that would dominate the IMSA racing circuit.

Greenwood’s modifications to the Corvette were extensive. He widened the car’s body to accommodate massive racing tires and improve aerodynamics. The iconic flared fenders and distinctive bodywork were born out of this need for increased tire width. The Greenwood IMSA Corvette was immediately recognisable by its bold and aggressive appearance.
