Off the line, the RS6 Performance Avant hits 100 km/h in 3.46 s versus 3.55 s for the M5 Touring. Despite lacking instant torque, 630 hp of power compensates. The 0.09 s gap is negligible: both vehicles are neck and neck.
At 200 metres, the RS6 Performance Avant is doing 165 km/h against 165 km/h for the M5 Touring. The gap is 0.07 s. The gap remains stable from the start.
At 400 metres standing start, the RS6 Performance Avant crosses the line in 11.30 s versus 11.38 s. The 0.08 s gap represents roughly 4 m of track - barely a car length.
Past 400 metres, the RS6 Performance Avant continues to build its lead. At 600 metres, it runs at 231 km/h versus 232 km/h. At 1,000 metres, the RS6 Performance Avant finishes in 20.37 s versus 20.40 s, with a 0.04 s lead.
Electronically capped at 305 km/h, the M5 Touring 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.
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 5.06 seconds. The 0.09 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
