What kind of gas did the first car use?
History of the automobile
Steam-powered road vehicles, both cars and wagons, reached the peak of their development in the early 1930s with fast-steaming lightweight boilers and efficient engine designs. Internal combustion engines also developed greatly during WWI, becoming simpler to operate and more reliable. The development of the high-speed diesel engine from 1930 began to replace them for wagons, accelerated in the UK by tax changes making steam wagons uneconomic overnight. Although a few designers continued to advocate steam power, no significant developments in production steam cars took place after Doble in 1931.
