The start: 0 to 100 km/h

Off the line, the Cayenne GTS hits 100 km/h in 5.56 s versus 7.97 s for the X4 xDrive20d. At this point, the Cayenne GTS leads by 2.41 s and sits roughly 9 m ahead.

From 100 km/h to 400 metres

At 200 metres, the Cayenne GTS is doing 137 km/h against 113 km/h for the X4 xDrive20d. The gap is 1.08 s. The challenger starts to claw back ground.

At 400 metres standing start, the Cayenne GTS crosses the line in 13.70 s versus 15.80 s. The 2.10 s gap represents roughly 79 m of track - a gap visible to the naked eye.

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 156 km/h. At 1,000 metres, the Cayenne GTS finishes in 24.70 s versus 29.28 s, with a 4.58 s lead.

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 X4 xDrive20d at 213 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 9.74 kg/hp) and transmission (Unknown vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 13.55 seconds. The 2.41 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
