¼-mile: 11.5 sec @ 123 mph
And the M8:
60 mph: 2.5 sec
100 mph: 6.3 sec
150 mph: 15.5 sec
170 mph: 22.0 sec
Rolling start, 5–60 mph: 3.5 sec
Top gear, 30–50 mph: 2.3 sec
Top gear, 50–70 mph: 2.4 sec
1/4 mile: 10.7 sec @ 129 mph
The only metric they’re similar is the 30-50 and 50-70 passing times. So if all you did was slam the gas from 35 MPH to 70, the speed limit in most places, I could see why you would think that they’re not that different.
Otherwise, the M8 is over a second faster to 100, 3 seconds faster to 150, and almost a second faster from a rolling race at 5 mph. And it’s 1/4 mile time is almost a second faster with a 6 MPH trap speed difference.
The M850i is a fast car and an awesome overall package, but let’s not act like the M8 won’t destroy it in a race. On the street, rolling at 20 mph, I could see how they feel similiar and the M850i is more comfortable ride wise so I can see why someone would chose it over an M8. I was also thinking about an M850i for this reason, but there’s really nothing like a true M and I wanted to try that out.

What year was the M850 tested?
Most of my testing was slow and moderate speed rolls-didn’t do any launches and stuck with more real world driving. A ~4400LB vehicle doing ~123mph traps would generally require more than 523hp from what I recall comps to previous 911 turbo tests when they were making similar pwr/~500hp and qm traps, as they’re much lighter, so the ~600hp dyno for the m850 still makes some sense here. Furthermore my guess is the M8C is making more than it’s advertised hp as well and I would luv to see stock dynos on an m8c, my guess is the delta would be somewhat similar.
