During 19th century vehicles were most promising. Drive technology. "Jamais Contente" in 1899, was the first vehicle to exceed the speed of 100 km/h. In 1911, first Start motor was invented, which helped the petrol vehicles to get started very easily. In early 1900s, due to coming of petrol engines in existence it became powerful day by day which made the electric engines to disappear. The breakthrough of these vehicles due the fuel price deduction as discovery of many oil wells encouraged. Mid of the 20th century, saw the revival of theoretical interest in vehicles, partially due to the oil crisis of late 1970s. After the tremendous improvements in between 80s and 90s of power electronics, a electric motor could be driven more efficiently. Last two decades have seen an inclination towards more energy efficiency vehicles. This has stimulated the production of electric vehicles. Presently, most of the automotive manufacturers are now after the production of electric vehicles or keeping it as their basic.
