The electric engine is being celebrated as the drive of the future by its fans. A little known fact: The e-car is not an invention of our time. It had already been built five years before the first gasoline car. The combustion engine became predominant in the 20th century because oil became a particularly cheap and energy rich fuel. Today circumstances are being reversed: Oil is getting scarcer and more expensive; batteries are becoming cheaper and more powerful. This is what gives the e-drive the chance to go into mass production after more than 100 years.
