So, along with developing a new Pontiac Engineering building in 1949–1951, your decision to re-direct the V8 to an OHV design delayed its introduction before 1953 model year, however Buick division was introducing its new engine (nailhead V-8) in 1953 and asked the corporation to put on back or delay Pontiac's V-8 introduction before the 1955 model year which it did. But testing comparisons to the OHV Oldsmobile V8 revealed the L-head couldn't compete performance-wise. This was initially meant to be an L-head engine, and 8 experimental units were built and extensively tested by the end of the 1940s.

The typical transmission is really a four-speed overdrive automatic, but a six-speed, close-ratio manual transmission can be obtained as an option. Pontiac GTO feature a 6.0-liter V8 rated at 400 horsepower and 395 pound-feet of torque. Regardless that transmission is selected, all GTOs feature a limited-slip differential and electronic traction control.

American manufacturers had begun to supply downsized alternatives to the gigantic cruisers that had ruled the highways in previous decades. Nonetheless it wasn't before 1960s that the Pontiac brand truly arrived to its own. Pontiac came to market with the compact Tempest. By equipping the automobile with the powerful 389 cubic-inch V8 from the full-size car line, Pontiac created the initial "muscle car." Phenomenally successful, the GTO helped define the burgeoning muscle car category. In 1964, Pontiac made its biggest impact yet with the creation of the GTO choice for the Tempest. Pontiac also saw tremendous success throughout the latter part with this decade with its Firebird and Firebird Trans Am.

These also were the foundation for the Tri-Power setups on the engines. PMD used Carter 1-barrel carburetors for quite some time, but by the time of the next generation V8 engines had switched mostly to 2-barrel offerings. This is accomplished two ways, mechanically for the manual transmission models, and using a vacuum-switch on the automatics. The Tri-Power setup included one center carburetor with idle control and two end carburetors that did not contribute until the throttle was opened significantly more than halfway. This experienced various permutations since it was just a factory installed option in from 1957-1966.

Nevertheless when driven more aggressively, the vehicle feels heavy and the steering a little slow and numb. When driven more aggressively, the car can feel ponderous because of its significant body roll and slow and numb steering. Best to help keep the car pointed straight and allow V8 work its magic, Pontiac which, naturally, has been the point of the GTO considering that the beginning. The Pontiac GTO has a luxury carlike ride quality, and when pushed a little, this indicates to deal with predictably and respectably, despite a fair level of body roll. Blazing engine performance and powerful brakes, however, showcase true muscle car roots.

Neither the NHTSA nor the IIHS conducted crash tests on the 2022 Pontiac GTO. All 2022 Pontiac GTOstandards include four-wheel disc brakes, traction control, multi-stage front airbags, and an emergency that disables car systems and opens doors when an airbag is installed. The medial side airbags aren't available and stability management can also be not available.

Apart from the displacement advantage the brand new engine had redesigned cylinder heads with various valve angles and larger ports. The Quadrajet design continued until 1990 for Oldsmobile V8 applications, along side added computer controls to meet up emissions and fuel economy standards. The different valve angles enable larger diameter intake and exhaust valves. There have been many tests when a Tri-Power set-up was added to a 400" or 428" engine they made, much more, H.P. By the finish of the muscle car era, the Quadrajet setup had end up being the nearly ubiquitous choice on PMD engines.

New models such as the Vibe, Solstice and G8 made Pontiac a brandname to think about in several segments. For a time, your time and effort was bearing fruit. It's expected 2010 is likely to be Pontiac's a year ago for new models. The'90s saw the launch of Pontiacs like the Sunfire and Montana minivan. In hopes of recapturing past glory, the division embarked on an agenda to retire aged models and introduce all-new ones with distinctive styling and personality. Pontiac has slowly lost sales because of changing tastes and deficiencies in differentiation between its models and Pontiac those of other GM divisions. However, GM's financial troubles in 2008 and 2009 have triggered their decision to phase out Pontiac as a brand.

Neither the NHTSA nor the IIHS have conducted crash tests on the GTO. Side airbags aren't available, nor is stability control. All Pontiac GTOs come standard with four-wheel antilock disc brakes, traction control, multistage front airbags and an urgent situation mode that shuts down the vehicle's systems and unlocks the doors in the event of an airbag deployment.
