911 Carrera GTS Cabriolet vs Bmw 750d xDrive: chronicle of a drag race at 294 km/h
The launch: 0 to 100 km/h
Off the line, the 911 Carrera GTS Cabriolet hits 100 km/h in 4.16 s versus 4.60 s for the Bmw 750d xDrive. At this point, the 911 Carrera GTS Cabriolet leads by 0.44 s and sits roughly 5 m ahead.
From 100 km/h to 400 metres
At 200 metres, the 911 Carrera GTS Cabriolet is doing 153 km/h against 145 km/h for the Bmw 750d xDrive. The gap is 0.41 s. The gap remains stable from the start.
At 400 metres standing start, the 911 Carrera GTS Cabriolet crosses the line in 12.12 s versus 12.80 s. The 0.68 s gap represents roughly 34 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 217 km/h versus 204 km/h. At 1,000 metres, the 911 Carrera GTS Cabriolet finishes in 21.83 s versus 23.09 s, with a 1.26 s lead.
What the numbers don’t tell you
Both rivals are electronically governed, but not at the same level: the 911 Carrera GTS Cabriolet is capped at 304 km/h, the Bmw 750d xDrive at 250 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 (3.11 kg/hp vs 4.88 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 6.94 seconds. The 0.44 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 750d xDrive to 100 km/h. This difference is clearly noticeable in spirited driving and widens on standing starts.
