Off the line, the RS6 Performance Avant hits 100 km/h in 3.46 s versus 4.54 s for the Z4 M40i. At this point, the RS6 Performance Avant leads by 1.08 s and sits roughly 11 m ahead.
At 200 metres, the RS6 Performance Avant is doing 165 km/h against 147 km/h for the Z4 M40i. The gap is 0.92 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 12.70 s. The 1.39 s gap represents roughly 69 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 205 km/h. At 1,000 metres, the RS6 Performance Avant finishes in 20.37 s versus 22.95 s, with a 2.58 s lead.
Electronically capped at 250 (i.e. 155 mph - industry threshold) km/h, the Z4 M40i 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 4.51 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 6.76 seconds. The 1.08 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, RS6 Performance Avant wins (3,46 s vs 4,54 s).
