Pontiac GTO

The Pontiac GTO (Gran Turismo Omologato) was an automobile built by Pontiac Division of General Motors in the United States from 1964 to 1974, and by GM subsidiary Holden in Australia from 2004 to 2006. It is considered an innovative, and now classic muscle car of the 1960s and 1970s. From 1964 until midway through 1973 it was closely related to the Pontiac Tempest/LeMans and for the 1974 model year it was based on the Pontiac Ventura. The 21st century GTO is essentially a left-hand drive Holden Monaro, itself a coupe variant of the Holden Commodore.

The GTO was the brainchild of Pontiac engineer Russell Gee, an engine specialist; Bill Collins, a chassis engineer; and Pontiac chief engineer John De Lorean. In early 1963, General Motors management issued an edict banning divisions from involvement in auto racing. At the time, Pontiac's advertising and marketing approach was heavily based on performance, and racing was an important component of that strategy. With GM's ban on factory-sponsored racing, Pontiac's young, visionary management turned its attention to emphasizing street performance.

In his autobiography “Glory Days,” Pontiac chief marketing manager Jim Wangers, who worked for the division’s contract advertising and public relations agency, states that John DeLorean, Bill Collins and Russ Gee were indeed responsible for the GTO's creation. It involved transforming the upcoming redesigned Tempest (which was set to revert to a conventional front-engine, front transmission, rear-wheel drive configuration) into a "Super Tempest" with the larger 389 CID (6.5 L) Pontiac V8 engine from the full-sized Pontiac Catalina and Bonneville in place of the standard 326CID (5.3 L) Tempest V8. By promoting the big-engine Tempest as a special high-performance model, they could appeal to the speed-minded youth market (which had also been recognized by Ford Motor Company's Lee Iacocca, who was at that time preparing the Ford Mustang).

The name, which was DeLorean's idea, was inspired by the Ferrari 250 GTO, the highly successful race car. It is an acronym for Gran Turismo Omologato, Italian for homologated for racing in the Grand tourer class. The name drew protest from purists, who considered it close to sacrilege.
