Audi has dropped an official video that gives us a background look into the development of the e-tron. Don't think it was necessary for them to throw shade at Tesla, as that company is really the only reason why models like this are in development.
At some point what seems to be a solution sometimes turn out to be a marketing ploy and in the auto industry its easy to get away with such practices.I'm just curious to see how 'revolutionary' their acclaimed energy recuperation is. This is something that every automaker has in place and it only provides very minor boosts to overall range.
