The Roadmaster was an automobile built by the Buick division of General Motors. The origins of the Roadmaster name date to 1936 when Buick added names to its entire model lineup to celebrate the engineering improvements and design advancements over their 1935 models. Buick’s Series 40 was named the Special, the Series 60 was named the Century and the Series 90 — Buick’s largest and most luxurious vehicle — was named the Limited. The Series 50 was retired, but new for the model year was the Series 80 Roadmaster. The implications of the name were clear, for as the 1936 Buick sales catalogue said, “It literally named itself the first time a test model leveled out on the open highway.”
Styling changes for 1938 were modest, with a longer hood extending to a now nearly vertical grill, taller bumper guards and redesigned hubcaps, but the effect was striking. Important changes were made to both engine and chassis. The ride was improved by replacing the rear leaf springs with coil springs, supported by double-acting shock absorbers that were some four times the size of any others on the market. The frame X-member was changed from I-beam to channel construction and all wood structural elements were replaced with steel. The engine combustion chambers were redesigned and new “turbulator” pistons raised the compression ratio from 5.9 to 6.5:1, resulting in an increase in horsepower to 141.
These top of the range limited edition Buick Speed 90s were only driven by the wealthiest and most politically involved such as the Lithuanian president in 1938- Mr A. Semtona. Finished in black with green interior this very special car is still the epitome of luxurious road driving as its spaciousness and quality are to this day unmatchable.
