Description

The Auburn 851 Supercharged 8 Speedster Boattail was one of the most striking and innovative automobiles of the 1930s, embodying both performance and elegance. Equipped with a 4.6-liter Lycoming inline-eight engine fitted with a Schwitzer-Cummins supercharger, it produced an impressive 150 horsepower, allowing it to achieve speeds exceeding 100 mph. The power was delivered through a three-speed manual transmission, complemented by Auburn’s advanced Columbia dual-ratio rear axle, which enhanced highway performance and fuel efficiency.

Designed under the direction of Gordon Buehrig, the 851 Speedster featured an unmistakable boattail rear end, flowing fenders, and a bold grille that gave it a dynamic and aerodynamic look. The low-slung profile and Art Deco styling made it one of the most visually stunning cars of its era. The interior was equally refined, with luxurious leather upholstery, an engine-turned dashboard, and elegant instrumentation, providing both comfort and a racing-inspired aesthetic.

Marketed as a true driver’s car, the Auburn 851 Supercharged 8 Speedster was one of the few vehicles of its time guaranteed to exceed 100 mph, a claim backed by factory testing. It was also relatively affordable for a high-performance vehicle, offering an exceptional blend of speed, engineering, and craftsmanship. Today, it is considered one of the most collectible American classics, admired for its breathtaking design, historical significance, and mechanical sophistication.
