The start: 0 to 100 km/h

Off the line, the Cayenne S E-Hybrid hits 100 km/h in 5.57 s versus 5.82 s for the Q7 SUV. At this point, the Cayenne S E-Hybrid leads by 0.25 s and sits roughly 6 m ahead.

From 100 km/h to 400 metres

At 200 metres, the Cayenne S E-Hybrid is doing 131 km/h against 129 km/h for the Q7 SUV. The gap is 0.26 s. The gap remains stable from the start.

At 400 metres standing start, the Cayenne S E-Hybrid crosses the line in 13.82 s versus 14.16 s. The 0.33 s gap represents roughly 15 m of track - two to three car lengths.

Beyond 400 metres: top speed comes into play

Past 400 metres, the Cayenne S E-Hybrid continues to build its lead. At 600 metres, it runs at 180 km/h versus 177 km/h. At 1,000 metres, the Cayenne S E-Hybrid finishes in 25.54 s versus 26.06 s, with a 0.52 s lead. Both vehicles have similar top speeds (237 vs 235 km/h), preventing any comeback.

What the numbers don’t tell you

Both rivals are electronically governed, but not at the same level: the Cayenne S E-Hybrid is capped at 243 km/h, the Q7 SUV at 240 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 plug-in hybrid powertrains, the difference comes down to power-to-weight ratio (5.57 kg/hp vs 6.05 kg/hp) and transmission (Unknown vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 9.29 seconds. The 0.25 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
