Off the line, the RS6 Performance Avant hits 100 km/h in 3.46 s versus 4.47 s for the Bmw M440i xDrive. At this point, the RS6 Performance Avant leads by 1.01 s and sits roughly 8 m ahead.
At 200 metres, the RS6 Performance Avant is doing 165 km/h against 146 km/h for the Bmw M440i xDrive. The gap is 0.84 s. The challenger starts to claw back ground.
At 400 metres standing start, the RS6 Performance Avant crosses the line in 11.30 s versus 12.66 s. The 1.35 s gap represents roughly 66 m of track - a gap visible to the naked eye.
Past 400 metres, the RS6 Performance Avant continues to build its lead. At 600 metres, it runs at 231 km/h versus 204 km/h. At 1,000 metres, the RS6 Performance Avant finishes in 20.37 s versus 22.96 s, with a 2.60 s lead.
Electronically capped at 250 (i.e. 155 mph - industry threshold) km/h, the Bmw M440i xDrive 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 (3.45 kg/hp vs 4.65 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 6.77 seconds. The 1.01 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
