- Buick advertised its “Valve in Head” motor (overhead valves).

- First year for Series 50 to use synchromesh transmission.

One of the most obvious styling changes for Buick in 1931 was a new radiator cap with a figure 8, denoting that all Buicks now sported straight-8 ohv engines.


The four-door sedan had a 221 cid engine capable of producing 77 hp. The Series 50 replaced the Marquette, a short-lived companion marque for Buick.


Standard equipment now included mechanical brakes, Delco-Remy ignition, and Hotchkiss drive with conventional transmission.


There were six body styles offered in the Series 50.  There were 33,180 Series 50 produced in 1931 at a list price of just under $2000.
