1968
GM redesigned its A-body line for 1968, with more curvaceous, "fastback" styling. The previous 115 inch (292 cm) wheelbase was shortened to 112 inches (284 cm) for all two-door models. Overall length was reduced 5.9 inches (150 mm) and height dropped half an inch (12 mm), but overall weight was up about 75 pounds (34 kg). Pontiac abandoned the familiar stacked headlights for hidden headlights behind the split grille (actually a US$52.66 option, but seen on many GTOs). The signature hood scoop was replaced by dual scoops on either side of a prominent hood bulge extending rearward from the protruding nose.
A unique feature was the body-color Endura front bumper. It was designed to absorb impact without permanent deformation at low speeds. Pontiac touted this feature heavily in advertising, showing hammering at the bumper to no discernable effect. Though a rare option, a GTO could be ordered with "Endura Delete", in which case the Endura bumper would be replaced by a chrome front bumper and grille from the Pontiac Le Mans. This model year further emphasized the curvacious "coke bottle" styling, as viewed from the side.
Powertrain options remained substantially the same as in 1967, but the standard GTO engine's horsepower rating rose to 350 hp (261 kW) @ 5,000 rpm. At mid-year, a new Ram Air package, known as Ram Air II, became available. It included freer-breathing cylinder heads, round port exhaust and the 744 cam. Horsepower rating was not changed, although actual output was likely somewhat higher. Another carry-over from 1967 was the 4-piston caliper disc brake option. While most 1968 models had drum brakes all around, this rare option provided greater stopping power and could be found on other GM A-Body vehicles of the same period. 1968 was also the last year the GTOs offered separate vent, or "wing", windows—and the only year for crank-operated vent windows.
Another feature was concealed windshield wipers, hidden below the rear edge of the hood. They presented a cleaner appearance and were another Pontiac first for the industry. Another popular option, actually introduced during the 1967 model year, was a hood-mounted tachometer, located in front of the windshield and lighted for visibility at night. An in-dash tachometer was also available, but the hood tachometer became something of a status symbol.
Redline bias-ply tires continued as standard equipment on the 1968 GTO, though they could be replaced by whitewall tires at no extra cost. A new option was radial tires for improved ride and handling. However, very few were delivered with the radial tires because of manufacturing problems encountered by supplier B.F. Goodrich. The radial tire option was discontinued after 1968. Pontiac did not offer radial tires as a factory option on the GTO again until the 1974 model.
Hot Rod tested a four-speed standard GTO and obtained a quarter mile reading of 14.7 seconds at 97 mph (156 km/h) in pure stock form. Motor Trend clocked a four-speed Ram Air with 4.33 rear differential at 14.45 seconds @ 98.2 mph (158.0 km/h) and a standard GTO with Turbo-Hydramatic and 3.23 gears at 15.93 seconds @ 88.3 mph (142.1 km/h). Testers were split about handling, with Hot Rod calling it "the best-balanced car [Pontiac] ever built," but Car Life chiding its excessive nose heaviness, understeer, and inadequate damping.
Now facing serious competition both within GM and from Ford, Dodge, and Plymouth—particularly the low-cost Plymouth Road Runner—the GTO won Motor Trend's Car of the Year award, and sales remained strong at 87,684 (which would be the second-best sales year for the GTO).
1969
The 1969 model did not have the vent windows, had a slight grille and taillight revision, moved the ignition key from the dashboard to the steering column, and the gauge faces changed from steel blue to black. In addition, the rear quarter-panel mounted side marker lamps changed from a red lens shaped like the Pontiac "V" crest to one shaped like the broad GTO badge.
The previous economy engine and standard 350 hp 400 in³ V8 remained, while the 360 hp engine was in its last year. The 400 in³ Ram Air III was rated at 366 hp (273 kW) @ 5,100 rpm, while the top option was the 370 hp (276 kW) Ram Air IV, which featured special header-like high-flow exhaust manifolds, high-flow cylinder heads, a specific high-rise aluminum intake manifold, larger Rochester QuadraJet four-barrel carburetor, high-lift/long-duration camshaft, plus various internal components capable of withstanding higher engine speeds and power output. Unlike the big-block Chevy and Hemi motors, the Ram Air IV utilized hydraulic lifters. As a result, it did not overheat in traffic, nor did it foul spark plugs, which set it apart from the large-displacement performance engines seen in other muscle cars.
By this time, the gross power ratings of both Ram Air engines were highly suspect, bearing less relationship to developed horsepower and more to an internal GM policy limiting all cars except the Corvette to no more than one advertised horsepower per ten pounds of curb weight. The higher-revving Ram Air IV's advertised power peak was actually listed at 5,000 rpm—100 rpm lower than the less-powerful Ram Air III.
The Ram Air V was introduced in 1969. It was a special 400 block with newly designed high compression tunnel port heads and a special high rise intake manifold. A prototype GTO so equipped could go 0-60 mph in 5.2 seconds, and the quarter-mile time was 11.5 seconds at 123 mph (198 km/h). Ram Air Vs were not installed in GTOs at the factory; it was available only as an aftermarket product.
The significant event of 1969 was the launch of a new model called 'The Judge'. The Judge name came from a comedy routine, "Here Comes the Judge", used repeatedly on the "Rowan & Martin's Laugh-In TV" show. Advertisements used slogans like "All rise for The Judge" and "The Judge can be bought." As originally conceived, the Judge was to be a low-cost GTO, stripped of some gimmicks to make it competitive with the Plymouth Road Runner. During its development, however, it was decided to make it the ultimate in street performance and image. The resulting package ended up being US$337.02 more expensive than a standard GTO, and included the Ram Air III engine, styled wheels, Hurst shifter (with a unique T-shaped handle), wider tires, various decals, and a rear spoiler. Pontiac claimed that the spoiler had some functional effect at higher speeds, producing a small but measurable down force, but it was of little value at legal speeds except for style. The Judge was initially offered only in "Carousel Red," but late in the model year a variety of other colors became available.
The GTO was surpassed in sales both by the Chevrolet Chevelle SS396 and the Road Runner, but 72,287 were sold during the 1969 model year, with 6,833 of them being The Judge.
