Cayenne Turbo S vs Bmw i4 M50 xDrive: chronicle of a drag race at 279 km/h
The launch: 0 to 100 km/h
Off the line, the Bmw i4 M50 xDrive hits 100 km/h in 3.92 s versus 4.36 s for the Cayenne Turbo S. The instant torque of 795 Nm from the electric motor makes the difference. At this point, the Bmw i4 M50 xDrive leads by 0.44 s and sits roughly 6 m ahead.
From 100 km/h to 400 metres
At 200 metres, the Bmw i4 M50 xDrive is doing 155 km/h against 152 km/h for the Cayenne Turbo S. The gap is 0.35 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 12.42 s. The 0.41 s gap represents roughly 22 m of track — two to three car lengths.
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 211 km/h. At 1,000 metres, the Bmw i4 M50 xDrive finishes in 21.97 s versus 22.41 s, with a 0.45 s lead. Despite a higher top speed (279 km/h), the Cayenne Turbo S never recovers its launch deficit.
What the numbers don’t tell you
On paper, the Cayenne Turbo S combines 570 hp, 800 Nm and 2,170 kg — a clear theoretical edge over the Bmw i4 M50 xDrive. Yet the Bmw i4 M50 xDrive launches quicker. At standstill, both motors deliver peak torque from 0 rpm: the decisive factor is no longer raw power, but available grip. If the Bmw i4 M50 xDrive has a better traction coefficient (tyres, weight distribution, traction control calibration), it puts down more force despite inferior specs — exactly what the simulation reflects, calibrated on manufacturer 0-100 km/h times.
Both rivals are electronically governed, but not at the same level: the Cayenne Turbo S is capped at 282 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 6.36 seconds. The 0.44 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Bmw i4 M50 xDrive has a clear edge over the Porsche Cayenne Turbo S to 100 km/h. This difference is clearly noticeable in spirited driving and widens on standing starts.
