1908 American Underslung 50 HP Roadster
Revolutionary chassis engineering transformed American automotive performance when Fred Tone designed an innovative underslung frame that ran beneath the axles, dramatically lowering the center of gravity.
This breakthrough created what many consider the United States’ earliest true sports car, predating both the Mercer Raceabout and the Stutz Bearcat by several years.
The massive 476.5-cubic-inch T-head inline four-cylinder engine produced 50 horsepower, delivering genuinely impressive performance for the era. A four-speed manual transmission and 124-inch wheelbase provided a solid foundation for this road-going powerhouse.
Front and rear underslung leaf spring suspension complemented the low-slung chassis design, while a transmission brake and rear-wheel drum brakes handled stopping duties.
This particular example (chassis 1427) carries remarkable provenance through legendary collectors including Lindley Bothwell, D. Cameron Peck, John Wallerich, and Richie Clyne.
As one of the earliest surviving American Underslungs retaining original roadster coachwork and its powerful 50-horsepower engine, it represents both historical significance and authentic period character.
The combination of brute power, advanced chassis design, and relatively lightweight construction created handling characteristics that allowed the Underslung to compete with European imports while establishing America’s performance car foundation.
