Bmw X6 M50i vs 911 Carrera 4 GTS (MT): chronicle of a drag race at 309 km/h
The launch: 0 to 100 km/h
Off the line, the 911 Carrera 4 GTS (MT) hits 100 km/h in 4.13 s versus 4.26 s for the Bmw X6 M50i. At this point, the 911 Carrera 4 GTS (MT) leads by 0.13 s and sits roughly 2 m ahead.
From 100 km/h to 400 metres
At 200 metres, the 911 Carrera 4 GTS (MT) is doing 161 km/h against 154 km/h for the Bmw X6 M50i. The gap is 0.15 s. The gap remains stable from the start.
At 400 metres standing start, the 911 Carrera 4 GTS (MT) crosses the line in 11.97 s versus 12.29 s. The 0.33 s gap represents roughly 17 m of track — two to three car lengths.
Beyond 400 metres: top speed comes into play
Past 400 metres, the 911 Carrera 4 GTS (MT) continues to build its lead. At 600 metres, it runs at 225 km/h versus 214 km/h. At 1,000 metres, the 911 Carrera 4 GTS (MT) finishes in 21.24 s versus 22.14 s, with a 0.90 s lead.
What the numbers don’t tell you
Both rivals are electronically governed, but not at the same level: the Bmw X6 M50i is capped at 250 km/h, the 911 Carrera 4 GTS (MT) at 309 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 (4.23 kg/hp vs 3.25 kg/hp) and transmission (Automatic vs Manual).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 6.19 seconds. The 0.13 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Porsche 911 Carrera 4 GTS (MT) is slightly faster than the Bmw X6 M50i to 100 km/h. The edge holds on standing starts but may narrow at higher speeds depending on aerodynamic load.
