About This Car

- Quick Specs -

All General Motors cars received a new look for 1942. Where front fenders had previously ended ahead of the front door, the new designs, from Chevrolet right through to Cadillac, carried them back almost to the mid-point of the door. Unique, however, was the treatment applied to Buick’s two-door Supers and Roadmasters, where “Airfoil fenders” extended fully across the door and quarter panel to meet the leading edge of the rear fender. For 1946, this touch was applied to all Supers and Roadmasters.

GM had scheduled new bodies for the larger 1948 Oldsmobiles, Buicks and Cadillacs, those using the big “C body.” At the last minute, Buick president Harlow Curtice canceled his division’s participation, and ordered one more year of the old design. Thanks to the Airfoil fenders, though, it still looked up to date, and helped distinguish Buick from its corporate siblings.

Not everything about the 1948 Buick Roadmaster was carried over, however. The principal new feature was under the skin, an automatic transmission. In contrast to the Hydra-Matic used by Oldsmobile and Cadillac, Buick’s new Dynaflow had a torque converter, which provided truly shiftless motoring. Optional on the Roadmaster only, it enjoyed immediate popularity.

This car was auctioned off by RM Auctions in August 2009 at the Shotwell Gustafson Pavilion at Meadow Brook Hall, Rochester, Michigan.
