Off the line, the M5 CS hits 100 km/h in 3.03 s versus 3.66 s for the RS 5 Avant. Despite lacking instant torque, 635 hp of power compensates. At this point, the M5 CS leads by 0.63 s and sits roughly 4 m ahead.
At 200 metres, the M5 CS is doing 170 km/h against 156 km/h for the RS 5 Avant. The gap is 0.60 s. The gap remains stable from the start.
At 400 metres standing start, the M5 CS crosses the line in 10.81 s versus 11.72 s. The 0.90 s gap represents roughly 48 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 218 km/h. At 1,000 metres, the M5 CS finishes in 19.94 s versus 21.35 s, with a 1.41 s lead.
Both rivals are electronically governed, but not at the same level: the RS 5 Avant is capped at 250 (i.e. 155 mph - industry threshold) km/h, the M5 CS at 305 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.
Instant electric torque gives an advantage off the line. The higher top speed of the combustion engine gives an advantage over longer distances. The distance at which one catches the other depends on the top speed differential.
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 5.51 seconds. The 0.63 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 3,66 s).
RS 5 Avant goes from 0 to 100 km/h in 3,66 seconds (calibrated simulation).
