Off the line, the X4 M40d hits 100 km/h in 4.81 s versus 5.81 s for the Cayenne S. At this point, the X4 M40d leads by 1.00 s and sits roughly 11 m ahead.
At 200 metres, the X4 M40d is doing 138 km/h against 133 km/h for the Cayenne S. The gap is 0.66 s. The challenger starts to claw back ground.
At 400 metres standing start, the X4 M40d crosses the line in 13.14 s versus 13.99 s. The 0.84 s gap represents roughly 38 m of track - a gap visible to the naked eye.
Past 400 metres, the X4 M40d continues to build its lead. At 600 metres, it runs at 192 km/h versus 186 km/h. At 1,000 metres, the X4 M40d finishes in 24.09 s versus 25.30 s, with a 1.21 s lead. Both vehicles have similar top speeds (258 vs 250 (i.e. 155 mph - industry threshold) km/h), preventing any comeback.
Both rivals are electronically governed, but not at the same level: the Cayenne S is capped at 258 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 (5.16 kg/hp vs 5.94 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 8.88 seconds. The 1.00 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, X4 M40d G02 wins (4,81 s vs 5,81 s).
Cayenne S goes from 0 to 100 km/h in 5,81 seconds (calibrated simulation).
