For anyone who didn't already know, the rev limiter kicks in a 5,000rpm.
Been driving our old slow-revving MG for the past fortnight, but in the Passat today I overtook a slow moving lorry, in second, and quickly hit the rev limiter (I'd forgotten how quickly it revs out). At first I didn't realise what it was (sounded like an F1 car going down the pit lane) and wondered if I'd gone into limp mode, so I left it in gear till I was past - bit worrying with a bend coming up.
I would imagine the car behind disappeared in a cloud of black smoke....
