The Volkswagen Nils concept isn't the first time Volkswagen's threatened to change the automotive paradigm. It isn't even the second time. But it is the first time they've also threatened to turn conventional wisdom on fuel efficiency since World War II on its head.
If you'll recall from advance info, Nils weighs 1,000 pounds, and with a 30-peak-hp (20 hp nominal power) electric motor it can get from 0-60 in 11 seconds. No speed demon, this, but since you're alone in the cockpit, you have no one to impress, right? Screw the old "When you ride alone" posters — maybe that single-seater deal isn't a bad idea after all.
And yet, here we are still driving regular, old cars to work instead of batshit trikes or Bonneville bullet cars that get 200 mpg (that's miles per gallon, not mph) powered by tea tree oil. But will we go solo in semi-open-wheeled quads with butterfly doors? Probably not. Never.
