Off the line, the X4 M40d hits 100 km/h in 4.94 s versus 5.56 s for the Cayenne GTS. At this point, the X4 M40d leads by 0.62 s and sits roughly 10 m ahead.
At 200 metres, the X4 M40d is doing 137 km/h against 137 km/h for the Cayenne GTS. The gap is 0.42 s. The challenger starts to claw back ground.
At 400 metres standing start, the X4 M40d crosses the line in 13.29 s versus 13.70 s. The 0.41 s gap represents roughly 19 m of track - two to three car lengths.
Past 400 metres, the gap narrows. The X4 M40d maxes out at 250 (i.e. 155 mph - industry threshold) km/h while the Cayenne GTS keeps accelerating towards 261 km/h. At 600 metres, the gap has dropped to 0.39 s.
At 1,000 metres, the X4 M40d finishes in 24.38 s versus 24.70 s, with just 0.32 s to spare. The Cayenne GTS fails to fully close the launch gap.
Both rivals are electronically governed, but not at the same level: the Cayenne GTS is capped at 261 km/h, the X4 M40d at 250 (i.e. 155 mph - industry threshold) km/h. This isn’t a physical engine limit - it’s a manufacturer choice, usually for tyre safety or homologation reasons. Neither car reaches its true aerodynamic top speed.
With two combustion powertrains, the difference comes down to power-to-weight ratio (4.96 kg/hp vs 5.81 kg/hp) and transmission (Unknown vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 8.33 seconds. The 0.62 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.
