The Auburn 851 Supercharged Speedster (serial 851 33216 E) is a celebrated example of Gordon Buehrig's landmark 1935–1936 boattail design, powered by a Schwitzer-Cummins supercharged straight-eight producing 150 horsepower with a Columbia dual-ratio rear axle. Documented from 1945, the car passed through several notable ACD enthusiast hands before receiving a meticulous concours-quality restoration in its believed-original Cigarette Cream and maroon livery. Certified Category 1 by the ACD Club, it subsequently won the Roy Faulkner Trophy for Best Auburn twice and placed second in class at the 2018 Pebble Beach Concours d'Elegance.
