Several Italians recorded designs for wind driven vehicles. The first was Guido da Vigevano in 1335. It was a windmill type drive to gears and thus to wheels. Various designed a similar vehicle which was also never built. Later Leonardo DA Vinni designed a clockwork driven tricycle with tiller steering and a differential mechanism between the rear wheels.

A Catholic priest named Father Ferdinand Veriest has been said to have built a steam powered vehicle for the Chinese Emperor Chen Lung in about 1678. There is no information about the vehicle, only the event. Since Thomas Newcomer didn't build his first steam engine until 1712 we can guess that this was possibly a model vehicle powered by a mechanism like Hero's steam engine, a spinning wheel with jets on the periphery. Newcomer's engine had a cylinder and a piston and was the first of this kind, and it used steam as a condensing agent to form a vacuum and with an overhead walking beam, pull on a rod to lift water. It was an enormous thing and was strictly stationary. The steam was not under pressure, just an open boiler piped to the cylinder. It used the same vacuum principle that Thomas Saver had patented to lift water directly with the vacuum, which would have limited his pump to less than 32 feet of lift. Newcomer's lift would have only been limited by the length of the rod and the strength of the valve at the bottom. Somehow Newcomer was not able to separate his invention from that of Saver y and had to pay for Savery's rights. In 1765 James Watt developed the first pressurized steam engine which proved to be much more efficient and compact that the Newcomen engine.
