Off the line, the Bmw M5 CS hits 100 km/h in 3.03 s versus 7.74 s for the Bmw 420i xDrive. At this point, the Bmw M5 CS leads by 4.71 s and sits roughly 17 m ahead.
At 200 metres, the Bmw M5 CS is doing 170 km/h against 115 km/h for the Bmw 420i xDrive. The gap is 3.01 s. The challenger starts to claw back ground.
At 400 metres standing start, the Bmw M5 CS crosses the line in 10.81 s versus 15.61 s. The 4.79 s gap represents roughly 175 m of track - a gap visible to the naked eye.
Past 400 metres, the Bmw M5 CS continues to build its lead. At 600 metres, it runs at 231 km/h versus 160 km/h. At 1,000 metres, the Bmw M5 CS finishes in 19.94 s versus 28.71 s, with a 8.77 s lead.
Both rivals are electronically governed, but not at the same level: the Bmw M5 CS is capped at 305 km/h, the Bmw 420i xDrive at 238 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 8.64 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 12.85 seconds. The 4.71 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 7,74 s).
M5 CS F90 goes from 0 to 100 km/h in 3,03 seconds (calibrated simulation).
