Dates vary from 1860 to 1863 on when Lenoir built his automobiles.
It is apparent that he built a small carriage with his engine around 1860.
His automobile of 1862 was capable of 3 kilometers per hour.

In 1861, he put one of his engines in a boat.

In 1863, Lenoir demonstrated a second three-wheeled carriage, the Hippomobile, little more than a wagon body set atop a tricycle platform.
It was powered by a 2543 cc (155 in³; 180×100 mm, 7.1×3.9in) 1.5 hp, "liquid hydrocarbon" (petroleum) engine with a primitive carburettor which was patented in 1886.
It successfully covered the 11 km (7 mi) from Paris to Joinville-le-Pont and back in about ninety minutes each way, an average speed less than that of a walking man (though doubtless there were breakdowns).
This succeeded in attracting the attention of Tsar Alexander II, and one was sent to Russia, where it vanished; Lenoir was not pleased.
In 1863, he sold his patents to Compagnie parisienne de gaz and turned to motorboats instead, building the first naptha, a Ligroin fueled four-cycle in 1888.
Jules Verne wrote in his 1863 novel Paris in the Twentieth Century of boulevards crowded with horseless carriages, "the Lenoir machine applied to locomotion."
