1965 Pontiac GTO

The Tempest line, as well as the GTO, was restyled for the 1965 model year, adding 3.1 inches (79 mm) to the general length whereas holding a similar distance and interior dimensions.

It had Pontiac's characteristic vertically stacked quad headlights. Overall weight enhanced regarding one hundred avoirdupois unit (45 kg). The lining space enhanced nearly V-J Day. heavy-duty  shocks were commonplace, as was a stronger front antisway bar. The dashboard style was modified, associate degreed an optional  rally gauge cluster ($86.08) side a additional fair measuring instrument and pressure gauge. a further possibility was a breakerless junction transistor ignition.

The 389 engines received revised cylinder heads with re-cored intake passages and high rise intake manifolds, rising respiration. 

Rated power enhanced to 335 HP (250 kW) at five,000 revolutions per minute for the bottom four—barrel engine; the Tri-Power engine was currently rated 360 HP (270 kW) at five,200 rpm. The 'S'-cammed Tri-Power engine had slightly less peak torsion rating than the bottom engine 424 lb·ft (575 N·m) at three,600 revolutions per minute versus 431 lb·ft (584 N·m) at three,200 rpm. Transmission and shaft quantitative relation decisions remained a similar. The three-speed manual was commonplace, whereas 2 four-speed manual transmissions (wide or shut ratio) or two-speed automatic were optional.

The restyled GTO had a brand new simulated hood scoop. 

A rarely seen dealer-installed possibility consisted of a metal underhood pan and gaskets to open the inside track, creating it a chilly air intake. the inside track was low enough that its effectiveness was questionable (it was unlikely to choose up something however physical phenomenon air), however it allowed additional of the engine's roar to flee. Another cosmetic modification was the black "egg-crate" grille.

Car Life tested a 1965 GTO with Tri-Power and what they thought-about the foremost fascinating choices (close-ratio four-speed manual transmission, power-assisted steering, aluminous brakes, rally wheels, 4.11 limited-slip differential, and "Rally" gauge cluster), with a complete sticker value of US$3,643.79. With 2 testers and instrumentation aboard, they recorded 0–60 miles per hour (0–97 km/h) in five.8 seconds, the standing linear unit in fourteen.5 seconds with a entice speed of one hundred miles per hour (160 km/h), associate degreed an ascertained high speed of 114 miles per hour (182.4 km/h) at the engine's half-dozen,000 revolutions per minute separate. A four-barrel Motor Trend check automobile, a heavier convertible incapacitated by the two-speed transmission and therefore the lack of a restricted slip differential, ran 0–60 mph in seven seconds and thru the linear unit in sixteen.1 seconds at eighty nine miles per hour (142.4 km/h).[citation needed]

Major criticisms of the GTO continued  to center on its slow steering (ratio of seventeen.5:1, four turns lock-to-lock) and mediocre brakes. automobile Life was glad with the aluminous brakes on its GTO, however Motor Trend and test found the machine drum brakes with organic linings to be alarmingly inadequate in high-speed driving.

Sales of the GTO, abetted by a selling and promotional campaign that enclosed songs and numerous merchandise, over doubled to seventy five,342. It spawned several imitators, each among different weight unit divisions and its competitors.
