CONFIDENCE 91%Why this result?
The Porsche Cayenne Turbo is faster at 0-100 km/h, but the Bmw i4 M50 xDrive compensates at high speed thanks to higher peak power or top speed. At 400 m, Bmw i4 M50 xDrive leads by 0.05 s.

Cayenne Turbo vs Bmw i4 M50 xDrive: chronicle of a drag race at 285 km/h
The launch: 0 to 100 km/h
Off the line, the Cayenne Turbo hits 100 km/h in 3.87 s versus 3.92 s for the Bmw i4 M50 xDrive. Despite lacking instant torque, 550 hp of power compensates. The 0.05 s gap is negligible: both vehicles are neck and neck.
From 100 km/h to 400 metres
At 200 metres, the Cayenne Turbo is doing 151 km/h against 155 km/h for the Bmw i4 M50 xDrive. The gap is 0.05 s. The gap remains stable from the start.
At 400 metres standing start, the Bmw i4 M50 xDrive crosses the line in 12.01 s versus 12.06 s. The 0.05 s gap represents roughly 3 m of track — barely a car length.
Beyond 400 metres: top speed comes into play
Past 400 metres, the Bmw i4 M50 xDrive continues to build its lead. At 600 metres, it runs at 216 km/h versus 208 km/h. At 1,000 metres, the Bmw i4 M50 xDrive finishes in 21.97 s versus 22.14 s, with a 0.18 s lead. Despite a higher top speed (285 km/h), the Cayenne Turbo never recovers its launch deficit.
What the numbers don’t tell you
Both rivals are electronically governed, but not at the same level: the Cayenne Turbo is capped at 285 km/h, the Bmw i4 M50 xDrive at 225 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 5.97 seconds. The 0.05 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Porsche Cayenne Turbo is slightly faster than the Bmw i4 M50 xDrive to 100 km/h. The edge holds on standing starts but may narrow at higher speeds depending on aerodynamic load.
