Bmw X4 M Competition vs Cayenne GTS: chronicle of a drag race at 262 km/h
The launch: 0 to 100 km/h
Off the line, the Bmw X4 M Competition hits 100 km/h in 4.13 s versus 4.92 s for the Cayenne GTS. At this point, the Bmw X4 M Competition leads by 0.79 s and sits roughly 9 m ahead.
From 100 km/h to 400 metres
At 200 metres, the Bmw X4 M Competition is doing 151 km/h against 141 km/h for the Cayenne GTS. The gap is 0.61 s. The challenger starts to claw back ground.
At 400 metres standing start, the Bmw X4 M Competition crosses the line in 12.22 s versus 13.11 s. The 0.89 s gap represents roughly 43 m of track — a gap visible to the naked eye.
Beyond 400 metres: top speed comes into play
Past 400 metres, the Bmw X4 M Competition continues to build its lead. At 600 metres, it runs at 207 km/h versus 195 km/h. At 1,000 metres, the Bmw X4 M Competition finishes in 22.35 s versus 23.91 s, with a 1.56 s lead. Both vehicles have similar top speeds (250 vs 262 km/h), preventing any comeback.
What the numbers don’t tell you
Both rivals are electronically governed, but not at the same level: the Bmw X4 M Competition is capped at 250 km/h, the Cayenne GTS at 262 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 (3.91 kg/hp vs 4.80 kg/hp) and transmission (Automatic vs Unknown).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 7.37 seconds. The 0.79 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Bmw X4 M Competition has a clear edge over the Porsche Cayenne GTS to 100 km/h. This difference is clearly noticeable in spirited driving and widens on standing starts.
