The start: 0 to 100 km/h

Off the line, the Cayenne GTS hits 100 km/h in 4.37 s versus 5.62 s for the X3 xDrive30d. At this point, the Cayenne GTS leads by 1.25 s and sits roughly 14 m ahead.

From 100 km/h to 400 metres

At 200 metres, the Cayenne GTS is doing 142 km/h against 130 km/h for the X3 xDrive30d. The gap is 0.90 s. The challenger starts to claw back ground.

At 400 metres standing start, the Cayenne GTS crosses the line in 12.66 s versus 13.96 s. The 1.30 s gap represents roughly 57 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 197 km/h versus 180 km/h. At 1,000 metres, the Cayenne GTS finishes in 23.37 s versus 25.66 s, with a 2.29 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 270 km/h, the X3 xDrive30d at 245 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 (4.88 kg/hp vs 6.75 kg/hp) and transmission (Unknown vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 9.01 seconds. The 1.25 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
