Nicolas Joseph Cugnot's Steam Vehicles
In 1769, the very first self-propelled road vehicle was a military tractor invented by French engineer and mechanic, Nicolas Joseph Cugnot. He used a steam engine to power his vehicle, which was built under his instructions at the Paris Arsenal. The steam engine and boiler were separate from the rest of the vehicle and placed in the front. It was used by the French Army to haul artillery at a whopping speed of 2 and 1/2 mph on only three wheels. The vehicle even had to stop every ten to fifteen minutes to build up steam power. The following year, Cugnot built a steam-powered tricycle that carried four passengers. In 1771, Cugnot drove one of his road vehicles into a stone wall, giving the inventor the distinct honor of being the first person to get into a motor vehicle accident. Unfortunately, this was just the beginning of his bad luck. After one of Cugnot's patrons died and the other was exiled, funding for Cugnot's road vehicle experiments dried up.
