The Oldsmobile F-Series is a car from Oldsmobile. Under the bonnet: Oldsmobile straight-6 engine.
The background
The Oldsmobile F-Series was a pre-WWII passenger car built from the 1928 through 1938 model years. The first generation continued the tradition of adding a series number for each model year; F-28, F-29, F-30 and F-31. The second generation, signified by a completely new bodystyle appearance was built from 1932 through 1938, all having been manufactured in Lansing, Michigan. 1926 saw the introduction of GM's most recognized business model, the use of common platforms shared amongst the brands, and Oldsmobile and Buick shared the GM B platform.
The F-Series was shared with the Buick Master Six and was also known as the Oldsmobile Six which was introduced as a name earlier in 1913. The F-Series was Oldsmobile's entry-level product using the Oldsmobile straight-6 engine, and was GM's mid-priced volume leader, offered in several body styles on a common wheelbase, while the Oldsmobile L-Series, with an Oldsmobile Straight-8 engine, was the top level vehicle with a longer wheelbase. It replaced the Oldsmobile Model 30 introduced in 1923, and was replaced by the Oldsmobile Series 60 and Oldsmobile Series 70 introduced in 1938. It was exported to Japan as a knock down kit and assembled at Osaka Assembly in Osaka, Japan.
The engineering
Power comes from Oldsmobile straight-6 engine. It shifts through a Automatic Safety Transmission (1937-1939) / 3-speed manual transmission. The layout matters: a front engine drives the rear wheels, the classic proportion — long bonnet, cabin set back — that most people picture when they picture a sports saloon or a grand tourer. These are manufacturer figures carried by Wikipedia and Wikidata, not road-test measurements.
Where it sits
Its family tree is legible: it took over from the Olds Six Model 30-E; its successor was the Olds Series 60 / Olds Series 70; assembly was at Lansing, Michigan. Its Oldsmobile stablemates include the Oldsmobile 442 and the Oldsmobile 88.
