The 1916 D-45 Touring was the top-selling model in 1916, a year when Buick switched its lineup from four- to six-cylinder engines. Sales tripled that year and reached six digits for the first time. Buick became the top-selling brand in the industry a few years later, with five-passenger touring models remaining most popular.
The 1917 Buick D-45 Touring Car was built in one of the lowest production years in Buick’s history, constrained by WWI supply allocations. Powered by the six-cylinder version of Buick’s famous valve-in-head engine, its 45-hp output made it a dynamic performer for the era.
