Depends where you look, i've seen from 4.9 - 5.2. I think the latter is probably more realistic. 0-100 around 12. 30-70 around 4 secs which is quite impressive but need high revs on the dial in 2nd gear for this! I'd love to be in an MTM or 300bhp plus S3 to see the M3 drivers face!!! It has to be said, there aren't many M3 owners out there that can actually drive the thing, on proper roads!
