These first vehicles set many modern standards, but each was a one-off design. They used a clutch pedal to operate a chain-driven gearbox. The vehicle also featured a front-mounted radiator.

For the 1894 Paris–Rouen Rally, Alfred Vacheron equipped his with a steering wheel, believed to be one of the earliest employments of the principle.
