Off the line, the 911 GT3 RS hits 100 km/h in 3.26 s versus 4.54 s for the Z4 M40i. At this point, the 911 GT3 RS leads by 1.28 s and sits roughly 12 m ahead.
At 200 metres, the 911 GT3 RS is doing 169 km/h against 147 km/h for the Z4 M40i. The gap is 1.11 s. The challenger starts to claw back ground.
At 400 metres standing start, the 911 GT3 RS crosses the line in 11.02 s versus 12.70 s. The 1.68 s gap represents roughly 82 m of track - a gap visible to the naked eye.
Past 400 metres, the 911 GT3 RS continues to build its lead. At 600 metres, it runs at 235 km/h versus 205 km/h. At 1,000 metres, the 911 GT3 RS finishes in 19.95 s versus 22.95 s, with a 3.00 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 (2.80 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 1.28 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Swap one of the two models to explore an equivalent duel in the same segment.
