Revived for the first time since 1942, the new Century shared the smaller and lighter Series 40 Special body and basic chassis but used the Roadmaster’s 200 HP V-8. It was Buick’s performance model.

A new piston crown better filled the combustion chamber and stopped the tendency of the engine to knock at low RPM and load. It also increased the power potential.

A smaller bore of 3.625 inches on the Buick V-8 produced a Special engine of 264 cubic inches. It was a welcome addition to the line that had relied on an I-8 designed in the 1930s.

Century – Revived for the first time since 1942, the new Century shared the Special’s body and basic chassis but used the Roadmaster engine. The new performance car carried three Ventiports per fender and was identical to the Special in most other exterior trim, except for “Century” in script on the quarter panels and the series designation within the deck ornament. It shared the Special’s instrument panel, with gauges set into twin round housings. Nylon cloth upholstery, with foam cushions that were two-tones in Riviera hardtops were standard. The convertible was trimmed in leather and had an outside rear view mirror and power operated windows, seat and top as part of its base equipment.

Century models were  2 door Sedan, 2-door Hardtop coupe, Convertible and 6-passenger Station Wagon.

Super – Using the new, larger General Motors C-body, with vertical windshield pillars and the new Panoramic windshield, the Super for 1954 was a big Buick for the budget minded. Identified by its three Ventiports per lender, the Super script on quarters and the series designation within the deck ornament, the Super shared other brightwork with the Roadmaster. Interiors were nylon and were plainer than in the Roadmasters. The Super did have the expensive car’s horizontal speedometer instrument panel. The convertible was upholstered in leather and had power-operated windows, seat and top, along with an outside rear view mirror on the left, as standard equipment.

Super models were 4-door Sedan, 2-door Hardtop, and Convertible.

Roadmaster – The top-of-the line Buick looked like the Super from the outside, with the exception of a fourth Ventiport on each front fender, “Roadmaster” was in script on the rear quarters and series identification within the deck ornament. Inside, the upholstery was much posher, with various nylon, broadcloth and leather combinations available depending on the model. Seats had chrome bands on the two-door models, and all cars were fully carpeted. Power steering, brakes and Dynaflow were standard features, as was a rear seat armrest on the sedan. All had the new instrument panel with horizontal speedometer. Hardtop and convertible models had an outside rear view mirror on the left, and the convertible was also equipped with power-operated windows, power seat adjustment, and top.

Models available were 2-door hardtop, 4-door Sedan, and Convertible.

Skylark – Buick’s prestige convertible was the only model in this series. A new tapered deck with big chrome fins was grafted onto the 1954 Century body to create the 1954 Skylark. Specific front fenders with a wide-open wheelhouse echoed at the rear wheelhouse and there were no Ventiports. Forty-spoke Kelsey-Hayes wire wheels were standard, along with leather trim, special emblems, power brakes, power steering, Dynaflow, 4-way powered seat, power top. power windows, Selectronic radio with power antenna, Easy-Eye glass, heater-defroster and whitewall tires.

The convertible was the only body style available.
