The video is not the best quality (not having an HD camera for this race should be a crime) and also does not offer the best angle but we can still see what the result is. The E60 M5 in the first run misses a shift so scratch that run. On the second run the F10 M5 gets a small lead but as the cars hit higher speeds the E60 M5 pulls impressively.
The F10 M5 is basically stock with the charcoal filters removed and a muffler delete. If the F10 M5 gets a tune, yes, it will walk this E60 M5. That said, a naturally aspirated M5 with a manual transmission pulling the new twin turbo dual clutch M5 shows how potent the S85 V10 is up top. It would have been nice if BMW gave that engine a pair of turbos.
