Bmw X6 M50i vs 911 Carrera GTS Cabriolet: chronicle of a drag race at 309 km/h
The launch: 0 to 100 km/h
Off the line, the 911 Carrera GTS Cabriolet hits 100 km/h in 3.70 s versus 4.26 s for the Bmw X6 M50i. At this point, the 911 Carrera GTS Cabriolet leads by 0.56 s and sits roughly 6 m ahead.
From 100 km/h to 400 metres
At 200 metres, the 911 Carrera GTS Cabriolet is doing 164 km/h against 154 km/h for the Bmw X6 M50i. The gap is 0.50 s. The gap remains stable from the start.
At 400 metres standing start, the 911 Carrera GTS Cabriolet crosses the line in 11.52 s versus 12.29 s. The 0.77 s gap represents roughly 40 m of track — a gap visible to the naked eye.
Beyond 400 metres: top speed comes into play
Past 400 metres, the 911 Carrera GTS Cabriolet continues to build its lead. At 600 metres, it runs at 227 km/h versus 214 km/h. At 1,000 metres, the 911 Carrera GTS Cabriolet finishes in 20.74 s versus 22.14 s, with a 1.40 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 GTS Cabriolet 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 3.17 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 6.19 seconds. The 0.56 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Porsche 911 Carrera GTS Cabriolet has a clear edge over the Bmw X6 M50i to 100 km/h. This difference is clearly noticeable in spirited driving and widens on standing starts.
