The CS seems significantly faster in a straight line (0.4s to 100km/h, 0.7s to 160km/h and 1.1s to 200km/h faster than the CP is nothing to scuff at). It must likely have a decent power-to-weight advantage...

I see here more like 29kg. Pretty close to the 30kg quoted by BMW...

I wonder how much of that is attributable to the sticky r-comps...

Seems they finally have done a great job with the factory chassis tuning this time around... |
This was the M4 SA was referring to, 1615 Kg, 0-200km/h 13.7. Looks like CP gained weight.
