context_page_description: The Pontiac GTO is an automobile that was manufactured by American automaker Pontiac from the 1964 to 1974 model years, and by GM's subsidiary Holden in Australia from the 2004 to 2006 model years.
  The first generation of the GTO was the first muscle car produced in the 1960s and the 1970s. The Pontiac GTO is considered by some to have started the trend with all four domestic automakers offering a variety of competing models.
  For the 1964 and 1965 model years, the GTO was an optional package on the intermediate-sized Pontiac LeMans. The 1964 GTO vehicle identification number started with 82, while the 1965 GTO VIN started with 237. The GTO became a separate model from 1966 to 1971. It became an optional package again for the 1972 and 1973 intermediate LeMans. For 1974, the GTO optional package was offered on the compact-sized Ventura.
  The GTO was selected as the Motor Trend Car of the Year in 1968.
  The GTO model was revived from 2004 to 2006 model years as a captive import for Pontiac, a left-hand drive version of the Holden Monaro, itself a coupé variant of the Holden Commodore.
context_section_description: General Motors redesigned its A-body line for 1968, with more curvaceous, semi-fastback styling. The wheelbase was shortened to 112.0 in (2,845 mm) on 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 lb (34 kg). Pontiac abandoned the familiar vertically stacked headlights in favor of a horizontal layout, but made hidden headlights available at extra cost. The concealed headlights were a popular option. 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 discernible effect. 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 LeMans.
  Powertrain options remained substantially the same as in 1967, but the standard GTO engine's power rating rose to 350 hp (260 kW) at 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 041 cam. The 'official' power rating was not changed. Another carry-over from 1967 was the four-piston caliper disc brake option. However, most 1968 models had drum brakes all around. The 1968 model year was also the last year the GTOs offered separate crank-operated front door vents.
  Concealed windshield wipers, which presented a cleaner appearance hidden below the rear edge of the hood, were standard on the GTO and other 1968 GM products after having been originally introduced on the 1967 Pontiac Grand Prix. A popular option, actually introduced during the 1967 model year, was a hood-mounted tachometer, located in front of the windshield and lit for visibility at night. An in-dash tachometer was also available.
  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 GTO equipped with the standard engine 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 GTO with 4.33 rear differential at 14.45 seconds at 98.2 mph (158.0 km/h) and a standard GTO with Turbo-Hydramatic and a 3.23 rear axle ratio at 15.93 seconds at 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 chided its excessive nose heaviness, understeer, and inadequate damping.
  Royal Pontiac, located in Royal Oak, Michigan, offered a 428/Royal Bobcat conversion of the 1968 GTO. For $650.00. a 390-horsepower 428 cubic inch engine was installed in place of the 400. The 428 CI engine was disassembled and blueprinted to produce more than the advertised factory 390 horsepower and easily spinning to 5700 RPM. Car and Driver road-tested the 428 CI powered car with the Turbo-Hydramatic transmission and 3.55 gears. It could do 0–60 MPH in 5.2 seconds, 0–100 in 12.9 seconds, and the 1/4 mile in 13.8 seconds at 104 mph. This compared to a  Car Life road test of a 400 CI powered GTO with a Ram Air engine, four-speed transmission, and 3.90 gear which did 0–60 in 6.6 seconds, 0–100 in 14.6 seconds, and the 1/4 mile in 14.53 at 99.7 mph. Car and Driver wrote that the 428 CI powered car was "a fine, exciting car for either touring or tooting around in traffic. Not overly fussy. Not difficult to drive–-up to a point. Too much throttle at the wrong time will spin the
