The 1917 Chevrolet Series D is an American automobile produced by Chevrolet between the period 1917 and 1918. Over 4,000 Series D cars were manufactured in the 1918 model year, and it was the first successful Chevrolet V8 car made. It was not until the year 1955 that Chevrolet made another V8. The Chevrolet Series D V8 internal combustion engine is a liquid-cooled, 4.7-liter capacity, designed and built by Chevrolet in 1917 and subsequently by General Motors Company’s new Chevrolet Division acquired as part of Chevrolet’s 1917 takeover of and merger into, GM in 1917 and 1918.

Advanced in design, the 1917 V-8 had a central camshaft operating vertical overhead valves in each bank, a counterweighted crankshaft, and detachable crossflow cylinder heads. Displacing 288 cubic inches and breathing through a Zenith two-barrel carburetor, it developed 55 horsepower at 2,700 rpm, running on 4.75:1 compression.
Billed as “A New and Greater Chevrolet,” the mid-priced V-8 cost $1,385 (more than a Buick) and failed to attract a sizable crop of customers. Riding a 120-inch wheelbase, the touring car weighed 3,200 pounds.
Not only was the V-8 Chevrolet’s most powerful engine yet, but years would pass before another could beat it in horsepower. Its new chassis heralded the forthcoming light-car trend, featuring quarter-elliptic cantilever springs at the rear.
