I added the G80 M3C to a comparison chart of various M models from a previous analysis so thought I'd go ahead and share here. As I need the Cd x A to run in the Sim I went to the bmw.de site to find the true area (2.34).
When trying to develop the acceleration curve for the X3MC it came reasonably close when the base power/torque was increased from the released numbers of 503HP/442lb-ft to what was being seen by actual dyno numbers of ~546HP/496lb-ft. Making an assumption that BMW is underestimating the G80's numbers as well, I used this HP/torque info as a simple estimation. Correcting for what I know we are currently documenting in the X3MC stock c/w the Sim, it suggests the G80 M3C could run 3.3xxs 0-60mph, and 11.2xxs at 126mph in the 1/4mile. As comparative reference, the X3MC stock record in our Sub-Forum is 11.618s at 117.72mph by robopp.
It will be interesting to see what your group finds with G80 dynos as more get tested in the field, as the Sim has usually been within 1-2mph of max speed as reported by BMW for almost every model I've run. But if the increased HP/torque numbers from our X3MC experience is used for the G80 as I did today, it shows the M3C capable of 191.7mph, nearly 12 mph faster than BMW's 180mph.
So am curious if the G8x series dynos closer to what BMW is actually reporting, unlike our F97/98 findings so far. Looking forward to seeing your data.  |
Great stuff!!! Thanks for that.
