Off the line, the M5 CS hits 100 km/h in 3.03 s versus 3.83 s for the M850i xDrive. At this point, the M5 CS leads by 0.80 s and sits roughly 7 m ahead.
At 200 metres, the M5 CS is doing 170 km/h against 160 km/h for the M850i xDrive. The gap is 0.70 s. The challenger starts to claw back ground.
At 400 metres standing start, the M5 CS crosses the line in 10.81 s versus 11.71 s. The 0.89 s gap represents roughly 49 m of track - a gap visible to the naked eye.
Past 400 metres, the M5 CS continues to build its lead. At 600 metres, it runs at 231 km/h versus 224 km/h. At 1,000 metres, the M5 CS finishes in 19.94 s versus 21.07 s, with a 1.13 s lead.
Both rivals are electronically governed, but not at the same level: the M5 CS is capped at 305 km/h, the M850i xDrive at 250 (i.e. 155 mph - industry threshold) km/h. This isn’t a physical engine limit - it’s a manufacturer choice, usually for tyre safety or homologation reasons. Neither car reaches its true aerodynamic top speed.
With two combustion powertrains, the difference comes down to power-to-weight ratio (2.87 kg/hp vs 3.64 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 5.50 seconds. The 0.80 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, M5 CS F90 wins (3,03 s vs 3,83 s).
M5 CS F90 goes from 0 to 100 km/h in 3,03 seconds (calibrated simulation).
