William T. Collins Jr.

William "Bill" Thaw Collins Jr. was an American automotive engineer who is most remembered as the "Father of the Pontiac GTO."
Collins was born on April 3, 1932 in Bryn Mawr, Pennsylvania. Collins studied engineering at Lehigh University, graduating in 1955. After school, Collins served in the U.S. Army as an engineer, testing advanced landing craft at the Aberdeen Proving Ground in Maryland. After leaving the Army, Bill worked at Pontiac as an engineer. In 1964, he was reviewing the 1964 Pontiac Tempest with John DeLorean and pointed out that the more powerful 389 engine from the brand's full-size cars would easily fit into the same space the Tempest's 326 engine. DeLorean greenlit the idea, and within a week, they had a running prototype of the Pontiac GTO, the car that many have claimed started the muscle car era.
In 1974, John DeLorean asked Collins to leave GM to lead development of the new DeLorean sports car. Collins would later resign from DeLorean Motor Cars in 1979 to start his own motorhome company, developing a 21-foot vehicle that could fit in a standard garage, powered by a BMW engine. Collins built a prototype motorhome in his garage, launching Vixen Motor Company in 1981.
Collins passed away on March 5, 2023, at his home in Michigan at the age of 90.
