Bmw X6 M50i vs 911 GT3: chronicle of a drag race at 313 km/h
The launch: 0 to 100 km/h
Off the line, the 911 GT3 hits 100 km/h in 4.08 s versus 4.26 s for the Bmw X6 M50i. At this point, the 911 GT3 leads by 0.18 s and sits roughly 6 m ahead.
From 100 km/h to 400 metres
At 200 metres, the 911 GT3 is doing 158 km/h against 154 km/h for the Bmw X6 M50i. The gap is 0.28 s. The gap widens compared to the 0-100.
At 400 metres standing start, the 911 GT3 crosses the line in 11.85 s versus 12.29 s. The 0.44 s gap represents roughly 23 m of track — two to three car lengths.
Beyond 400 metres: top speed comes into play
Past 400 metres, the 911 GT3 continues to build its lead. At 600 metres, it runs at 225 km/h versus 214 km/h. At 1,000 metres, the 911 GT3 finishes in 21.23 s versus 22.14 s, with a 0.90 s lead.
What the numbers don’t tell you
Electronically capped at 250 km/h, the Bmw X6 M50i never reaches its natural aerodynamic ceiling in this duel. That’s not a physical limit of the motor — it’s a deliberate manufacturer decision, typically tied to standard-fit tyre ratings or model-range positioning.
With two combustion powertrains, the difference comes down to power-to-weight ratio (4.23 kg/hp vs 3.16 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 0.18 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Porsche 911 GT3 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.
