Cayenne Turbo S vs Bmw X5 M50i: chronicle of a drag race at 279 km/h
The launch: 0 to 100 km/h
Off the line, the Cayenne Turbo S hits 100 km/h in 4.36 s versus 4.39 s for the Bmw X5 M50i. The 0.03 s gap is negligible: both vehicles are neck and neck.
From 100 km/h to 400 metres
At 200 metres, the Cayenne Turbo S is doing 152 km/h against 150 km/h for the Bmw X5 M50i. The gap is 0.00 s. The gap remains stable from the start.
At 400 metres standing start, the Cayenne Turbo S crosses the line in 12.42 s versus 12.48 s. The 0.06 s gap represents roughly 3 m of track — barely a car length.
Beyond 400 metres: top speed comes into play
Past 400 metres, the Cayenne Turbo S continues to build its lead. At 600 metres, it runs at 211 km/h versus 208 km/h. At 1,000 metres, the Cayenne Turbo S finishes in 22.41 s versus 22.56 s, with a 0.15 s lead.
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 X5 M50i 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 4.26 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 6.43 seconds. The 0.03 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Bmw X5 M50i 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.
