Why does four wheel drive hurt 0-60 times?
Discussion
Recently I've been watching old top gears / clarkson dvds and one thing has started to annoy me.
Whenever there's a 4wd vs rwd drag race, they always claim that the 4wd is at a disadvantage due to "bogging down off the line"
Now I'd understand that if we were talking about a Fiat Panda 4x4, but it's usually serious bits of kit with more than enough power to spin up all 4 wheels, meaning 4wd can only be an advantage.
PS, happy new year all!

My understanding is down to greater transmission losses because the engine has to get all of those drive shafts and differentials up to speed as well...
I would agree, but only in a lesser powered car. Cars like the RS4 could spin all 4 wheels with ease, so any transmission losses are nullified. chard said:

That said, I've not driven an RS4 so if you're saying a full RPM, side step the clutch launch wouldn't spin up all 4 tyres I'd believe you (but be a little surprised)

It's all down to the laws of Physics chaps.
Are there any 4x4 dragsters?.........
Ask the dragster guys why............
