Off the line, the M5 CS hits 100 km/h in 3.03 s versus 3.46 s for the RS6 Performance Avant. At this point, the M5 CS leads by 0.43 s and sits roughly 4 m ahead.
At 200 metres, the M5 CS is doing 170 km/h against 165 km/h for the RS6 Performance Avant. The gap is 0.40 s. The gap remains stable from the start.
At 400 metres standing start, the M5 CS crosses the line in 10.81 s versus 11.30 s. The 0.49 s gap represents roughly 28 m of track - two to three car lengths.
Past 400 metres, the gap narrows. The M5 CS maxes out at 295 km/h while the RS6 Performance Avant keeps accelerating towards 346 km/h. At 600 metres, the gap has dropped to 0.50 s.
At 1,000 metres, the M5 CS finishes in 19.94 s versus 20.37 s, with just 0.43 s to spare. The RS6 Performance Avant fails to fully close the launch gap.
Electronically capped at 305 km/h, the M5 CS never reaches its natural aerodynamic ceiling in this duel. That’s not a physical limit of the motor - it’s a deliberate manufacturer decision, typically tied to standard-fit tyre ratings or model-range positioning.
With two combustion powertrains, the difference comes down to power-to-weight ratio (2.87 kg/hp vs 3.45 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 5.02 seconds. The 0.43 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
