What Does GTO Stand For In Pontiac GTO?

For those who are inquisitive, we’ll disclose the meaning of what does GTO stand for in Pontiac* GTO? in a moment.

This is the point at which everything started. Pontiac* saw a need in the market in 1964. The full-size automobile industry was booming with powerful vehicles, but the mid-size sector lagged
behind in terms of performance and status.

This was the consequence of a General Motors* restriction on factory-sponsored racing, as well as a conventional engine size limit of 330 cubic inches. By providing the LeMans GTO, “Gran Turismo Omologato”, package as an option on the Tempest model, Pontiac* was able to get past these constraints.

Aside from the air scoops on the hood, it was distinguishable from the ordinary Tempest by special redline tires, heavy-duty suspension, and a three-speed tranny on the floorboard. It also came with a chromed air filter and rocker cover, as well as a distinctive instrument panel plate that had been engine turned.

The 1964 Pontiac* GTO horsepower specifications varied. As a standard model, the GTO used a 389 cubic inch V8, rated at 325 horsepower, derived from the Bonneville. That horsepower was increased to 348 bhp by installing a Tri-Power package, which replaced the original four-barrel carburetor with three double-barrel carbs.

The GTO immediately rose to superstar status, thanks to its 7.5-second 0-60mph performance and ability to complete the standing quarter-mile in less than 15 seconds. Sales skyrocketed to unprecedented levels… More than 32,000 vehicles were sold in the first year, exceeding Pontiac’s* goal of 5,000 sales. It became a muscle car phenom in its first year.

Pontiac* took advantage of the GTO’s phenomenal success by revamping the car’s front and rear for 1965. Stacked headlights were incorporated into the noses of Pontiac* full-size cars. The standard 389 now delivered 335 horsepower, while the Tri-Power version cranked out a monstrous 360 bhp. Hood scoops that were merely decorative on the 1964 model were now used to provide the ram-air system, which was available from your local Pontiac* dealership.

A year later, the GTO was introduced as a stand-alone model. Another restyle was carried out in order to give the automobile a more sculptured appearance. It had a midline form that kinked or curled upwards towards the back. Under the hood, there have been no modifications to the powertrain.

Pontiac* needed a fresh strategy in 1967 since General Motors* had banned twin carburetors on all models, with the exception of the Chevrolet Corvette*. In addition to being bored out, the 400 cid V8 was available in four distinct variations. For example, there was an “Economy” version with just 255 horsepower, which was one of the available options.

Another option was the “Standard” model, which had a power output of around 335 horsepower. Finally, there were two additional options available: the High Output and the Ram Air variants, both of which produced 360bhp. With a revised 112-inch wheelbase, the GTO received yet another facelift for 1968.

With the addition of concealed headlights to the options list, the revolutionary rubber Endura bumper was now standard. Both the Economy and Standard powerplants gained an additional 10 horsepower each, but the High Output and Ram Air motors maintained their 360 horsepower. The Judge GTO was introduced in the year 1969. In honor of a term from the television show “Laugh In,” this commemorative GTO was painted in a variety of bright colors and equipped with a substantial rear spoiler.

Two new Ram Air engines were made available, the 1969 GTO Judge horsepower ratings for each engine were 366 and 370 horsepower respectively. With each passing year, the GTO grew in both strength and speed…

A new look was introduced in 1970 with four visible headlamps and a more refined overall appearance. In spite of the Ram Air’s new 455 engine’s 360bhp, the VOE option was the 1970’s most revolutionary feature.

Using a “hot rod” concept, this Vacuum Operated Exhaust system was able to enhance the amount of power it could deliver. Back pressure was lessened in the exhaust, which resulted in increased performance and loudness as soon as the driver adjusted a knob on the dashboard.

General Motors* management swiftly pulled this option from the market, which was a shame. Power and emissions constraints were imposed on the GTO, as well as other GM* muscle cars, for the next three years, making it a less powerful vehicle. The GTO was no longer available as a stand-alone model as of 1972, and production was phased out in 1973.

GTO was resurrected as a sleek two-door coupe in 2004. It was more than a poser because of its 400bhp, six-liter, 364ci LS2 V8. It was certainly a legitimate “show and go” muscle car. Between 1965 and 1974, the GTO was in production. In 2004 to 2006, they were brought back. The 364.1 cubic inch V8 engine from the 2005 GTO was the most potent. It was capable of 400 horsepower and 400 lb-ft of torque. A six-speed manual gearbox was also offered. This vehicle was capable of reaching a top speed of 150 mph.
