Diesel — it's not just for buses and bro-trucks anymore! That's the message behind Audi's new ad for their 2014 TDI cars. That's right: a diesel car. No, it's not witchcraft, it's real!

As I learned covering the recent A6 and A7 TDI drive event, Audi is making a big push to get luxury car buyers into their diesel models. Much of that involves dispelling strangely persistent myths about diesel to Americans, like the notion that diesels are smelly, smoky, and slow.

Audi said during that event that their diesel owners still have people run up to them at gas stations frantically trying to stop them from "accidentally" putting diesel into their cars. Yes, that is an actual thing that happens. It's not just advertisement hype.

So hopefully this ad will show Americans once and for all that diesel is for cars, too, especially ones loaded down with insane amounts of torque like the A6 and A7. Now if they can just keep their diesel owners from putting gasoline in them, they'll be good.
