A version of the 1983 Chevrolet Corvette GTP racing car appeared at the 1984 Chicago Auto Show. Chevrolet said that the GTP (Grand Touring Prototype), was fitted with a modified and turbocharged 3.8-liter V-6 engine that developed more than 750 horsepower. The concept was finished white over silver. During the 1985 show, the GTP appeared once again, this time painted red and silver.
