The Dodge Senior (or Dodge Series 2249, Dodge Series 2251/2252, Dodge S Series, Dodge DB Series) was a large-sized passenger car by the American automaker Dodge presented in May 1927. It was built for a further two years following Dodge's merger with Chrysler in 1928.
Series 2249 (May 1927-January 1928)
The car was equipped with a 3676cc inline six-cylinder side-valve engine capable of generating 60 bhp (44 kW) of output at 2800 rpm. It was the first six-cylinder vehicle offered by Dodge. Engine power was transmitted from a single dry clutch to a three-speed gearbox, and from there to the rear wheels. The chassis had a 2946 mm wheelbase. It was offered as a four-door sedan, two-door coupe with two or fours seats, and a two-door convertible for two people. Hydraulic brakes on all four wheels was standard.
Series 2251/2252 (January 1928-July 1928)
The car was redesigned in January 1928, after less than a year of the Senior's production. This new series of vehicle was dubbed the Series 2251/2252. Even though the vehicle's capacity was not altered, it could now generate 68 bhp (50 kW) at 2800 rpm. In addition to the body styles offered for the earlier Series 2249, a sports version that featured contoured fenders, spoked wheels, and spare tires on the sides was now available.
S Series (July 1928-July 1929)
By mid-1928, the cars were thoroughly revised and received a longer wheelbase of 3048 mm. Also, the engine was bored out to 3959cc displacement and gave 78 bhp (57.3 kW) of output at 3000 rpm. The sports model was now only offered as a coupe and sedan, and standard two-door victoria and four-door landaulet body styles became available.
DB Series (July 1929-July 1930)
During mid-1929, the S Series was renamed to the DB Series, and models became largely reproduced. New technical features were implemented, including four-speed transmission. Only four bodies were offered: a sedan, coupe, roadster, and victoria.
The Dodge DH Series replaced the Senior in late 1930.
