Bmw i4 M50 xDrive vs Cayenne GTS Coupe: chronicle of a drag race at 266 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 4.35 s for the Cayenne GTS Coupe. The instant torque of 795 Nm from the electric motor makes the difference. Despite the faster sprint time, the Cayenne GTS Coupe is 4 m further along the track at this moment: stronger low-speed acceleration offsets a slower run beyond 100 km/h.
From 100 km/h to 400 metres
At 200 metres, the Bmw i4 M50 xDrive is doing 155 km/h against 142 km/h for the Cayenne GTS Coupe. The gap is 0.26 s. The challenger starts to claw back ground.
At 400 metres standing start, the Bmw i4 M50 xDrive crosses the line in 12.01 s versus 12.64 s. The 0.63 s gap represents roughly 31 m of track — a gap visible to the naked eye.
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 197 km/h. At 1,000 metres, the Bmw i4 M50 xDrive finishes in 21.97 s versus 23.34 s, with a 1.37 s lead. Despite a higher top speed (266 km/h), the Cayenne GTS Coupe never recovers its launch deficit.
What the numbers don’t tell you
Both rivals are electronically governed, but not at the same level: the Bmw i4 M50 xDrive is capped at 225 km/h, the Cayenne GTS Coupe at 270 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 6.90 seconds. The 0.43 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Bmw i4 M50 xDrive is slightly faster than the Porsche Cayenne GTS Coupe to 100 km/h. The edge holds on standing starts but may narrow at higher speeds depending on aerodynamic load.
