The start: 0 to 100 km/h

Off the line, the Cayenne hits 100 km/h in 5.63 s versus 5.74 s for the X4 xDrive30d. The 0.11 s gap is negligible: both vehicles are neck and neck.

From 100 km/h to 400 metres

At 200 metres, the Cayenne is doing 133 km/h against 130 km/h for the X4 xDrive30d. The gap is 0.09 s. The gap remains stable from the start.

At 400 metres standing start, the Cayenne crosses the line in 13.87 s versus 14.07 s. The 0.20 s gap represents roughly 9 m of track - barely a car length.

Beyond 400 metres: top speed comes into play

Past 400 metres, the Cayenne continues to build its lead. At 600 metres, it runs at 184 km/h versus 179 km/h. At 1,000 metres, the Cayenne finishes in 25.36 s versus 25.82 s, with a 0.46 s lead. Both vehicles have similar top speeds (245 vs 245 km/h), preventing any comeback.

What the numbers don’t tell you

Both rivals share the same electronic speed cap: the Cayenne and the X4 xDrive30d are governed to 245 km/h. At that speed, standard-fit tyres approach their safety threshold - an industrial ceiling common to most electric vehicles in this segment. Neither car shows its true aerodynamic potential in this duel.

With two combustion powertrains, the difference comes down to power-to-weight ratio (5.84 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 9.17 seconds. The 0.11 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
