They both had a deathwish, you aren't kidding. I wonder how many people behind them swerved and had their own accidents..
No way that was a stock RS4, certainly modded to pull that hard on a M5, probably a [insert turbo here] . A RS4 is more M3 territory, (and unfortunately, RS4 is the winner, generally). It is not going to pull that hard on a M5 like that without a hefty [insert turbo here]. But awesome cars both, that Audi has a big [insert turbo here]. If that had been an RS6, I wouldn't think it had a big [insert turbo here], but maybe just some good mods. A RS6 would pull on a M5, but not like that either. (And it did look like a A4 frame)
Hmmm.. I think that car had a.. turbo?
Sweet vid!!!
