Pontiac GTO

The GTO was the first "muscle car". The idea was "putting a big engine in a small car", although the GTO was based on the Le Mans and Tempest and wasn't all that small. It was named for the Ferrari GTO, whose name stood for "Gran Turismo Omoligato (Grand Touring Homologated). Despite this the GTO never competed in grand tourer racing, even when it was revived based on a Holden decades later. The GTO was mainly a stock car, competing in the Grand National days. A special Judge edition was provided in 1969.
