1959–1960 For 1959, Pontiac dropped the name "Chieftain" and "Super Chief" models for its junior-level series and renamed it "Catalina", while demoting the former top-line Star Chief to intermediate status eliminating the two door Star Chief Catalina, the only hardtop for the Star Chief was the four door hardtop and expanding the Bonneville nameplate to a senior series that included
sedans,
coupes, convertibles and Safari
station wagons. Styling highlights include thin-pillar rooflines and greater use of glass for increased visibility. Pillared four-door sedans feature six-window styling, while two-door hardtops were dubbed "bubbletops" due to the large wraparound bubble windshield and thin c-pillar and large rear window; four-door hardtops featured flat-blade rooflines with an overhang past the rear window. Wheelbases were 122" for Catalina and 124" for Star Chief and Bonneville inches, but overall length on Catalina was 7" shorter than Bonneville and Star Chief at . The 1959 Pontiacs featured a "split grille", which came about by accident when the styling studio was exploring grille design. Experimentally, a design for a conventional, full width, oval grille, containing horizontal quad headlights, was cut in two and the halves transposed. With the lights remaining at the extremities, this gave the split center, open ended look of the '59 Catalina. Along with the wider body came a 5" wider chassis in which the wheels were moved out towards the fenders. This not only improved the appearance of the car but led to improvements in ride and handling - spawning the term "wide track" ride and handling which Pontiac would use in its promotional efforts for many years to come. All Pontiacs were powered by various renditions of the new
389 cubic-inch Tempest V8 (which was later renamed from 1961 as the
Trophy V-8), which was basically a version of the previous 370 cubic-inch V8 with stroke increased to 3.75 inches (the 370ci was used in 1958-model Pontiacs and based on the Pontiac V8 design introduced in 1955). Catalinas came standard with a version of the 389 with two-barrel
carburetor and 8.6 to 1 compression mated to the three-speed
manual transmission. When the optional four-speed Hydramatic transmission was ordered, the standard engine was version of the same engine with higher 10.5 to 1 compression ratio. Available as a no-cost option with the Hydramatic transmission was the 215-horsepower 389 (dubbed the Economy V8) with 8.6 to 1 compression ratio which burned cheaper regular gasoline, instead of the premium and super-premium fuels required for the high-compression engines, and capable of achieving more than 20 MPG on the highway. Optionally available at extra cost were higher-power versions of the 389 V8 with four-barrel carburetion rated at with manual gearbox or 303 hp with Hydramatic, a 4-barrel carburetor version with a horsepower rating of 318 hp, or "Tri-Power" options with triple two-barrel carburetors and 330 hp or . Inside, a revised instrument panel featured a new horizontal sweep
speedometer along with minor changes in trim patterns.
1961–1964 The 1961 full-sized Pontiacs were completely restyled with more squared-off bodylines, the reintroduction of the split grille first seen in 1959 and dropped for 1960 and an all-new Torque-Box perimeter frame with side rails replacing the "X" frame chassis used since 1958. The new frame not only provides greater side-impact protection than the "X" design but also improves interior roominess. along with various "over the counter" performance options offered by Pontiac including aluminum bumpers and even lighter frames with drilled holes (which were dubbed the "Swiss cheese" frames). For 1963, Catalinas and other full-sized Pontiacs featured cleaner, squared-off bodylines and vertical headlights flanking the split grille, but retained the same dimensions and basic bodyshell of 1961-62 models except for the rear flanks of the new coke bottle styling and due to this styling the rear track was extended to the 59 and 60 Pontiac's 64" wide track. Engine offerings were revised as the and versions of the 389 V8 were dropped in favor of "production" versions of the larger rated at with four-barrel carburetor, with Tri-Power, or a "HO" with Tri-Power . The Super Duty 421 was still offered to racing teams during the early portion of the model year but discontinued after General Motors ordered Pontiac (and Chevrolet) to "cease and desist" from factory-supported racing efforts in February 1963. New options for 1963 included a tilt steering wheel that could be adjusted to six different positions, AM/FM radio and cruise control. With the downsized 1977 model, the Catalina Safari got a new two-way tailgate that could be opened to the side as a door or lowered as a tailgate which replaced the more complicated 1971-76 clamshell tailgate design. The wagons also shared the same full-coil spring suspension as their sedan counterparts, rather than the multi-leaf springs found on 1971-76 Safaris. As Pontiac V8s were completely
banned from the State of California beginning in 1977 due to the inability to meet the state's more stringent emission control standards, Catalinas (and Bonnevilles) sold in California were equipped with engines from other GM divisions through 1981. Those included the Buick 231 V6 and an assortment of V8s including the Chevrolet 305, Oldsmobile 307, Buick and Oldsmobile 350s, and Oldsmobile 403 V8. The Catalina was discontinued after the 1981 model year as Pontiac sought to abandon the full-sized car market as part of GM's continued downsizing program. When production of the Catalina nameplate ended in 1981, over 3.8 million Catalinas had been sold since 1959. ==Canada and Canadian exports==
