E. Paul du Pont's resources allowed him to hire top-quality automotive and management talent. The company's first product, the Model A, was introduced at the 1919 International Salon at the Commodore HotelinNew York City (an event for the wealthy by invitation only, along with the finest manufacturers and coach builders). The Model G was introduced in 1928, with a 5.3 liter side-valve straight eight engine of 125 hp (93 kW).
The Du Pont Model G was the first 8 cylinder model from Du Pont Motors in Wilmington, Delaware.
The car was powered by a Continental 12-K side-valve straight eight cylinder engine with a displacement of 321.8 c.i. (5.3 litre), delivering 125 bhp. Du Pont added an aluminum cover over the distributor, spark plugs and wiring for water and dust protection. There was a 3 speed transmission. Included were four-wheel hydraulic brakes, and hydraulic shock absorbers. Standard wheelbase was 136 in., with 141 in. available for formal coachwork, and a speedster with 125 in. There were 12 factory body styles to choose from, manufactured for Du Pont by Merrimac, Derham, and Waterhouse. The rolling chassis was available for other coachbuilders. Prices ranged from US$4,360 ($77,365 in 2023 dollars [3]) to US$5,750 ($102,029 in 2023 dollars [3]), with Speedsters up to US$6,125 ($108,683 in 2023 dollars [3]).
The Du Pont Model H was the last motor car line for Du Pont Motors. In 1930 the Model H was introduced, which was basically a Model G but with a longer wheelbase that measured 146-inches. A total of three were built consisting of a two car and two sport models. The sports chassis were later bodied as a sport phaeton and a closed-coupled sedan by Dietrich. The other received a formal Berline body and a flat radiator.
