The start: 0 to 100 km/h

Off the line, the Cayenne GTS hits 100 km/h in 5.56 s versus 5.67 s for the X6 xDrive40i. Despite the faster sprint time, the X6 xDrive40i is 2 m further along the track at this moment: stronger low-speed acceleration offsets a slower run beyond 100 km/h.

From 100 km/h to 400 metres

At 200 metres, the Cayenne GTS is doing 137 km/h against 132 km/h for the X6 xDrive40i. The gap is 0.03 s. The gap remains stable from the start.

At 400 metres standing start, the Cayenne GTS crosses the line in 13.70 s versus 13.94 s. The 0.24 s gap represents roughly 11 m of track - two to three car lengths.

Beyond 400 metres: top speed comes into play

Past 400 metres, the Cayenne GTS continues to build its lead. At 600 metres, it runs at 191 km/h versus 182 km/h. At 1,000 metres, the Cayenne GTS finishes in 24.70 s versus 25.47 s, with a 0.76 s lead. Both vehicles have similar top speeds (261 vs 248 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 GTS is capped at 261 km/h, the X6 xDrive40i at 248 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 6.29 kg/hp) and transmission (Unknown vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 8.87 seconds. The 0.11 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
