Pontiac GTO

The GTO was a sedan marketed by Pontiac in the sixties and seventies and again in the 2000s. Its name was from the Italian "Gran Turismo Omoligato", which meant "grand touring homoligated". The name is more appropriately used on the Ferrari GTO. The GTO is considered to be the first "muscle car" and credited with starting the "performance wars" of the sixties and seventies.

Original
The GTO was introduced in 1964 based on the Pontiac Le Mans. In 1969 the Pontiac Judge was introduced based on the GTO. The GTO continued until the Oil Crisis killed the performance car.

Concept Car
A concept GTO, based on the original's "Coke bottle" design, was introduced in 1999 but never produced.

Revival
A revival based on the Australian Holden Commodore was introduced in 2002. It lasted for a few years before Pontiac's discontinuation.

Motorsport
The GTO originally competed exclusively in NASCAR, never competing in actual GT racing despite its name.

The revival competed primarily in the Rolex Sports Car Series, where it actually was a grand tourer. It also competed in the SCCA's World Challenge series and the Continental Tire Sports Car Challenge.
