The 1964 Pontiac GTO was released on October 1, 1963, and fired up a Tri-Powered 389 CID V8 engine that, once ignited, was heard ’round the World.
With the creation of the GTO, Pontiac Motor Division kicked off a revolution of factory-built high-performance cars that caught all of the other auto manufacturers off guard… including its parent company, General Motors.
At the time, General Motors (GM) had the policy to cap the motor size to 330 CID V8 in a midsized car. However, everyone knew the quicker way to horsepower was more cubic inches.
Under the leadership of John DeLorean and with the help of Jim Wagners, these two figured out a loophole where they snuck in the full-zed car engine as part of an option package.
As the story goes, the 1964 Pontiac GTO was born and became the first car of the muscle car era.

The Genesis of the 1964 Pontiac GTO
If Pontiac Motor Division (PMD) would reach the youth market and capture their attention and pocketbooks, DeLorean and Wagners knew they couldn’t simply repeat what had been done in years past.
DeLorean and Wagners did what all the hot rodders of the day were already doing… they stuffed a full-sized car engine into a lighter-weight mid-sized car and bolted on a bunch of performance parts. It was a clever and effective magic formula.
What was the magic formula?
… Priced less than $3,000? Check!
.. Mid-sized lightweight car? Check!
… Full size car V8 engine? Check!
… A trio of optional two-barrel carbs? Check!
… Optional close-ratio 4-speed gearbox? Check!
… Dual exhaust? Check!
… Safe-T-Track positraction differential? Check!
The 1964 GTO checked all the right boxes for over 30,000 buyers. While sales initially started out slow, Pontiac sold six times its projected figures, with 32,450 units sold in the first year of production alone.
What helped catapult sales was a cover story featured in Car & Driver magazine. In its March 1964 issue, they declared the 1964 Pontiac GTO was faster in the quarter-mile than its namesake—the Ferrari 250 GTO.
While it has been rumored that Pontiac had swapped the block with a 421 CID V8 engine, the fact remains that it was in print as a Royal Bobcat tuned 389 CID V8, and, more importantly, people believed it.
With a base 389 VID V8 engine and options like a 4-speed manual transmission, Tri-Power carburetors, and positraction, it’s no wonder the Pontiac GTO became known as the first muscle car.
What does GTO stand for?
GTO stands for “Gran Turismo Omolgato“, which, loosely translated from Italian, means it’s a car certified to engage in various types of racing competitions. The GTO name was inspired by the successful Ferrari 250 GTO Italian race car. It was a marketing move made by John DeLorean to (not so subtly) state his GTO was an American-made performance car that meant business.
“In racing terms, ‘G.T.O.’ means ‘Gran Turismo Omologato.’ In Pontiac language, these three letters designate a special, white-hot Tempest.”
– Bob McVay, Motor Trend, Jan 1964.
1964 Pontiac GTO Option Package
In 1964, the Pontiac GTO option could be added to a Pontiac Tempest model on either a hardtop, coupe, or convertible body style for $295—the equivalent of $2,400 in today’s dollars.
When the GTO option was selected, it included roughly a dozen cosmetic and performance upgrades that transformed it from a grocery-getter to the quintessential muscle car we all know and love today.
