1931 Buick Series 50 Navigation
The most obvious visible styling change in the 1931 Buick was a new radiator cap. It features a figure 8, which denotes the availability of three totally new straight-eight engines. This handsome 4-door sedan has the 220 cid version, rated at 77bhp. It is a multiple award winner at Buick Club of America events, and has appeared at most of the major Concours in this country.
In 1931 all Buick models were powered by an eight-cylinder engine. To highlight this fact, Buick placed the number '8' on the radiator cap.
For 1931 Buick introduced the Series 50 which served as a replacement for the Marquette though it was mounted on the same 114-inch wheelbase. There were two series of the Series 8-50, with the first series beginning in July of 1930 and the second taking over in January of 1931. Standard equipment now included mechanical brakes, Delco-Remy ignition, and Hotchkiss drive with conventional transmission.
There were six body styles offered for the Series 50 and an additional bodystyle for the Second Series 50. The two-door Business Coupe with seating for two was the least expensive model, setting the buyer back $1,025. An extra ten dollars would buy the two-door sedan with seating for five. The most popular of all the First Series 50 vehicles was the four-door sedan with seating for five. In total, over 33,180 examples were produced in 1931. The Second Series 50 introduced a two-door Convertible Coupe which had seating for four. The vehicle would set the buyer back just under $2000. The Roadster from the first series became a Sport Roadster in the Second Series.
The Second Series brought with it the Silent Synchromesh transmission which had been reserved for more expensive Buick models. Also standard was the internal mechanical brakes and torque-tube drive.
The 1931 model year was significant for Buick, as cars were designed for both men and women. For the male audience the eight-cylinder engine was introduced with 104 horsepower, and for the female audience luxury was at her fingertips, with Mohair Wool interior, additional insulation to reduce road and wind noise. This particular model was the most popular model sold during the depression era.
Buick also introduced the Synchro-Mesh shift transmission this year.
The current owner has been working on the restoration for the last 10 years. The car was featured in the Buick Bugle, published by the Buick Club of America.
