Muscle car is a term used to refer to a variety of high-performance automobiles. The Merriam-Webster dictionary defines muscle cars as "any of a group of American-made 2-door sports coupes with powerful engines designed for high-performance driving." A large V8 engine is fitted in a 2-door, rear wheel drive, family-style mid-size or full-size car designed for four or more passengers. Sold at an affordable price, muscle cars are intended for mainly street use and occasional drag racing. They are distinct from two-seat sports cars and expensive 2+2 GTs intended for high-speed touring and road racing. Developed simultaneously in their own markets, muscle cars also emerged from manufacturers in Australia, South Africa, the United Kingdom, and elsewhere.
The Chevrolet Camaro is an automobile manufactured by General Motors under the Chevrolet brand, classified as a pony car and some versions also as a muscle car.

The car shared its platform and major components with the Pontiac Firebird, also introduced for 1967.
Four distinct generations of the Camaro were developed before production ended in 2002. The nameplate was revived again on a concept car that evolved into the fifth-generation Camaro; production started on March 16, 2009.

International Race of Champions (IROC) was a North American auto racing competition, promoted as an equivalent of an American All-Star Game or The Masters. Despite its name, the IROC was primarily associated with North American oval-racing culture.
Drivers raced identically-prepared stock cars set up by a single team of mechanics in an effort to make the race purely a test of driver ability. It was run with a small field of invited drivers (6–12). It was created and developed in 1972 by David Lockton, the developer of the Ontario Motor Speedway, launched in 1973, with Mark Donohue being the first driver to win the championship in 1974. The cars used that year were Porsche Carrera RSRs. Donohue's win in the fourth and last race of that season was his last win, as he unfortunately died in a Formula One crash at the Österreichring in practice for the 1975 Austrian Grand Prix. The series was not run in 1981, 1982, or 1983.
