Description
The Chevrolet Series AD Universal Roadster was introduced in 1930 as part of Chevrolet’s continued effort to offer stylish, affordable cars to the American public during a time of economic uncertainty. The Series AD, also known as the Universal, was the successor to the 1929 AC International, and while its changes were largely evolutionary, it retained a strong position in the market due to its solid engineering and updated styling.
The roadster body style was a sporty two-seater with a foldable fabric roof, often equipped with a rumble seat in the rear to accommodate one or two extra passengers. Unlike sedans or coupes, the roadster had no side windows—only removable side curtains—emphasizing its lightweight, open-air design.
Mechanically, the Series AD Universal Roadster featured Chevrolet’s proven 194 cubic inch inline-six engine, also known as the “Stovebolt Six.” It produced around 50 horsepower, a slight increase over the previous model year. This engine was praised for its reliability, simplicity, and relatively smooth performance, helping to maintain Chevrolet’s reputation for value and dependability.
The car came with a three-speed manual transmission and rear-wheel drive, with mechanical brakes on all four wheels. Its 109-inch wheelbase gave it a balanced stance and provided a comfortable ride for its size. The chassis and suspension, with semi-elliptic leaf springs, were typical of the era but robust enough for the road conditions of the time.
Visually, the 1930 Series AD featured updated styling touches, such as a slightly more streamlined body, a new radiator shell design, and a lowered roofline. The roadster model, in particular, had a distinct sporty charm with its exposed fenders, spare tire mounted on the side, and wire-spoke wheels.
Today, the Chevrolet Series AD Universal Roadster is a prized collector’s car, appreciated for its classic 1930s aesthetics, reliable six-cylinder engine, and the carefree spirit of the open-road experience it evokes. It’s a snapshot of an era when cars were becoming not just functional, but stylish expressions of personal freedom.
