Off the line, the X4 M40i hits 100 km/h in 4.75 s versus 6.22 s for the Cayenne S Hybrid. At this point, the X4 M40i leads by 1.47 s and sits roughly 9 m ahead.
At 200 metres, the X4 M40i is doing 142 km/h against 127 km/h for the Cayenne S Hybrid. The gap is 0.83 s. The challenger starts to claw back ground.
At 400 metres standing start, the X4 M40i crosses the line in 12.98 s versus 14.37 s. The 1.38 s gap represents roughly 59 m of track - a gap visible to the naked eye.
Past 400 metres, the X4 M40i continues to build its lead. At 600 metres, it runs at 198 km/h versus 175 km/h. At 1,000 metres, the X4 M40i finishes in 23.62 s versus 26.38 s, with a 2.77 s lead. Both vehicles have similar top speeds (236 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 Hybrid is capped at 242 km/h, the X4 M40i 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 (5.89 kg/hp vs 5.18 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 9.71 seconds. The 1.47 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, X4 M40i G02 wins (4,75 s vs 6,22 s).
Cayenne S Hybrid 958.1 goes from 0 to 100 km/h in 6,22 seconds (calibrated simulation).
