And there's a reason you don't see the full name of this gearbox written out in most articles covering anything Porsche: Those three letters stand for Porsche Doppelkupplungs getriebe. That's a bit of a mouthful, but it's pretty easy to remember once you read it through a few times. The first part is easy, because it's simply Porsche. That second...

  • Do vehicle exhaust systems need back pressure?
