Cayenne Turbo S vs iX xDrive50: 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 4.69 s for the iX xDrive50. Despite lacking instant torque, 570 hp of power compensates. At this point, the Cayenne Turbo S leads by 0.33 s and sits roughly 2 m ahead.
From 100 km/h to 400 metres
At 200 metres, the Cayenne Turbo S is doing 152 km/h against 144 km/h for the iX xDrive50. The gap is 0.26 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 12.93 s. The 0.51 s gap represents roughly 25 m of track — two to three car lengths.
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 200 km/h. At 1,000 metres, the Cayenne Turbo S finishes in 22.41 s versus 23.92 s, with a 1.50 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 iX xDrive50 at 200 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.
Instant electric torque gives an advantage off the line. The higher top speed of the combustion engine gives an advantage over longer distances. The distance at which one catches the other depends on the top speed differential.
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 7.07 seconds. The 0.33 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Porsche Cayenne Turbo S is slightly faster than the BMW iX xDrive50 to 100 km/h. The edge holds on standing starts but may narrow at higher speeds depending on aerodynamic load.
