Cayenne Turbo S vs Bmw X3 M Competition: chronicle of a drag race at 279 km/h
The launch: 0 to 100 km/h
Off the line, the Bmw X3 M Competition hits 100 km/h in 4.13 s versus 4.36 s for the Cayenne Turbo S. At this point, the Bmw X3 M Competition leads by 0.23 s and sits roughly 7 m ahead.
From 100 km/h to 400 metres
At 200 metres, the Bmw X3 M Competition is doing 151 km/h against 152 km/h for the Cayenne Turbo S. The gap is 0.25 s. The gap remains stable from the start.
At 400 metres standing start, the Bmw X3 M Competition crosses the line in 12.22 s versus 12.42 s. The 0.19 s gap represents roughly 10 m of track — two to three car lengths.
Beyond 400 metres: top speed comes into play
Past 400 metres, the gap narrows. The Bmw X3 M Competition maxes out at 250 km/h while the Cayenne Turbo S keeps accelerating towards 279 km/h. At 600 metres, the gap has dropped to 0.15 s.
At 1,000 metres, the Bmw X3 M Competition finishes in 22.37 s versus 22.41 s, with just 0.05 s to spare. The Cayenne Turbo S fails to fully close the launch gap.
What the numbers don’t tell you
Both rivals are electronically governed, but not at the same level: the Cayenne Turbo S is capped at 282 km/h, the Bmw X3 M Competition at 250 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 (3.81 kg/hp vs 3.91 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 6.36 seconds. The 0.23 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Bmw X3 M Competition is slightly faster than the Porsche Cayenne Turbo S to 100 km/h. The edge holds on standing starts but may narrow at higher speeds depending on aerodynamic load.
