Charles T. Jeffery's (Thomas' son) experimental prototypes of 1901 (Models A and B) used at least two radical innovations – steering wheels and front-mounted engines.

By the time Charles was ready for production in 1902, his father had talked him out of these wild dreams and convinced him to stick with tillers and engines under the seat.

Among them was a five-passenger, US$2,500 Rambler weighing 2,600 pounds (1,179 kilograms) and powered by a 250 horsepower (186 kilowatts) engine.

Charles T. Jeffery survived the sinking of the RMS Lusitania (a British luxury liner torpedoed by the Germans in World War I) in 1915 and decided to spend the rest of his life in a more enjoyable manner.

Charles W. Nash was caught in a power struggle for leadership at General Motors (GM) after successfully refocusing the automaker's management and production as well as increasing its sales and profits.

Its design and durability proved effective in traversing the muddy, rough, and unpaved roads of the times.

Both are powered by an 8-horsepower (6 kW; 8 PS), 98-cubic-inch (1.6 L) one-cylinder engine mounted beneath the seat, and are steered by a right-side tiller.

First-year production totals 1,500 units making Jeffery the second-largest car maker behind Olds Motor Works.
