1951 Buick Roadmaster Series 70

Buicks received all-new postwar styling in late-1949 for the 1950 model year, complete with a commanding presence, stunning design cues, a prominent 'bucktooth' grille, opulent interiors, and undeniable comfort. Buick distinguished its upper trim levels from its lower trim levels by the portholes on the side - the upper trim had four while the lower trims had three portholes. The late-1949 cars had a ventiport key and slot system to open the hood, while 1950 production cars had an inside hood release. Buick's top-level car, the Roadmaster, further distinguished itself from its siblings with larger engines, plusher interior trims, Roadmaster script located above the full-length bodyside molding, and extra chrome trim and brightwork.

Following the complete redesign a year earlier, the 1951 models were given only minor updates, mostly focusing on the front end with a more conventional bumper and grille assembly. Models included the entry-level Series 40 Special, the intermediate Super Series 50, and the top-of-the-line Roadmaster Series 70. Both the Special and the Super rested on a 121.5-inch platform, except the Super Sedan which was slightly larger at 125.5-inches. The Roadmaster was the longest and best equipped in the lineup, resting on a 126.25-inch wheelbase. The Sedan was even longer, at 130.25-inches. Full wheel covers were standard.

The Special and Super were powered by a 263.3 CID inline-8 with 120 horsepower, while the Roadmaster was endowed with a Fireball inline-8 with overhead valves, a 320.2 cubic-inch displacement, 7.2:1 compression, hydraulic valve lifters, five main bearings, a Stromberg or Carter two-barrel carburetor, and produced 152 horsepower at 3,600 RPM. The Special and Super came standard with a three-speed manual transmission while the Roadmaster had a Dynaflow drive automatic, option on the other models.

The interiors were cloth on closed body styles with carpeting on the floors. The convertible coupe and station wagons had a leather interior. The convertible had a power top, window, and seats. When the Custom interior option was ordered, it added leatherette door panel trim.

Body styles included a hardtop coupe, Deluxe hardtop coupe, sedan, convertible coupe, and station wagon. The Coupe had a base price of $3,140, the sedan listed for $3,200, and the convertible coupe sold for $3,450. The station wagon was the most expensive in the lineup, priced at $3,970. The sedan was the most popular, with 48,758 examples built, followed by the coupe with 12,901 examples, and the convertible coupe at 2,911. 679 examples were station wagons.

Within Alfred P. Sloan's G.M. hierarchy, Buick was just below Cadillac, and above Chevrolet, Pontiac, and Oldsmobile. This gave buyers a vast array of price points, and General Motors was able to cater to a plethora of needs and desires. The Cadillac was the most expensive, most powerful, most well-appointed vehicle within the lineup, but they were also the most expensive. The Buick's were big, comfortable, stylish, and offered many of the standard features found on the Cadillac at a more reasonable and affordable price. Chevrolet was the most utilitarian, basic, and affordable within the hierarchy.

Buick produced 404,695 vehicles during the 1951 calendar year, the company's second-highest number up to this point in history, allowing them to place fourth in America's automaker model-year output. The Roadmaster accounted for approximately 16-percent of Buick's total 1951 output.
