1948 Buick Series 70 Roadmaster news, pictures, specifications, and information

Convertible Coupe
 
The 1948 Buick Roadmaster Convertible was a pre-war design but it received the famous Dynaflow transmission, which was the first torque-converter automatic transmission on an American-built car. The engine is a 320.2 cubic-inch, in-line eight with a power rating of 144-150 hp.

Known for interior luxury and quiet operation, there were few other cars like them of this era. The sleek styling of these particular two-doors elicited an emotional response from the motoring community that surpassed the expectations of GM.

This is a low mileage car that has benefited from a frame-off restoration. It is equipped with hydraulically operated push-button controls for the top, windows and front seat.
Station Wagon
Designer: Hercules
 
Buick Roadmasters, produced between 1936 and 1958, were built on Buick's longest wheelbase and shared its basic structure with the higher end Oldsmobile's. Between 1946 and 1957, the Roadmaster was Buick's premium and best appointed model. The Estate Wagon 'Woody' body was built at the Hercules Body Company in Indiana which accounted for most Buick Estate Wagons as they were called rather than 'Station Wagons.' This car was once owned by the Harrah Collection and is in original color paintwork and original wood.

The 1948 Buick Roadmaster was a Harley Earl design featuring a 320 cubic-inch engine mated to a 2-speed Dynaflow automatic transmission. This convertible was purchased in May of 1998 by the current owner.

In 1948 a series script appeared on the front fenders and the white Tenelite steering wheel that had been used previously was traded in for a black one, in order match the change from a two-tone woodgrain instrument panel to a two-tone gray instrument panel, with silver tone instruments. A new optional Custom Trim option was offered, consisting of cloth upholstery with leather bolsters with the robe cord cover and lower door panels done in leatherette. The convertible models received power windows, seat and top as standard equipment.

The Roadmaster named first appeared on Buick automobiles in 1936 as a celebration of their engineering improvements and advancements in design. The Buick Series 80 became known as the Roadmaster. The Roadmasters were built on the longest wheelbase Buick had to offer. From 1946 through 1957 they were the most elegant and prestigious automobiles that Buick sold.

From 1936 through 1948 the Roadmaster appeared in coupe, sedan, convertible and station wagon bodystyles. A hardtop coupe was added in 1949 and dubbed the Riviera.

The Roadmaster named reappeared in 1991 and continued in production until 1996. It served as a replacement for the Electra model line and offered as an Estate Wagon. A sedan was introduced in 1992.

The end of the 1953 Buick Roadmaster station wagon meant the end of the last wood-bodied station wagon to be mass-produced in the United States. In 1996, the end of the Buick Roadmaster Estate Wagon meant the end of the full-size family station wagons.
