Introduction: In 1680, the renowned British scientist Newton conceived the idea of a jet-powered car, which utilized steam ejected from a nozzle to propel the vehicle, but he failed to build a physical prototype. 2. Gasoline: 1885 was a year of decisive breakthroughs in automobile invention. At that time, Benz, who worked in the same factory as Daimler, was also researching automobiles. 3. Electricity: The world's first research on electric vehicles was conducted by Hungarian engineer Ányos Jedlik, who completed an electric transmission device in his laboratory in 1828. The first practical electric vehicle was invented by American Anderson between 1832 and 1839. The battery used in this electric vehicle was relatively simple and non-rechargeable.
