what type of quattro does the R8 have?

[Audi05s4]

is there a really serious bias in the r8 awd system i ask this because i was watching this video http://www.dpccars.com/car-videos-08/02-07-08page-Audi-R8-doing-some-donuts.htm
and it seems the front wheels can stay completely stil as if it was a rwd car while doing donuts so i was just curious

That's about the pattern my S4 makes in the snow doing donuts. Like a little bullseye.

It's 85% rear bias.

[GramCracker]

It's 85% rear bias.

Its a 40/60 split.

Its a 40/60 split.

No, it's 85 rear, 15 front in standard condition, will change depending on the condition up to 35 to the front. It's not the 60/40 split :)

60/40 split is on the torsen based Quattro only.
