Having driven both (own an M5, just sold a C5):
There is a very simple answer. They are traveling above 80mph where the 6 really starts to suffer drivetrain losses, ditching up to 25% of its power before the power even gets to the road. The M5 has a very efficient drivetrain and has minimal losses compared to the quattro. The M5 is also much easier to keep in the power band at this speed and the power is relentless. There is nothing below £150/£200k that will beat an M5 above 100mph (see youtube for proof vs Lambos etc). Even Nigels C6, with its 760+bhp could only VMax 7mph higher than a 560bhp M5 at the last VMAX. Thats how efficient the M5 is. Had the race been from 0 to 60 the 6 would have left the M5 behind by a nose or so due to the overwhelming torque. They both have their uses.
Its taken me 3 months to realise just how good the BMW is, but now ive found its sweet spot there is no going back for now.
