Bmw 750Ld xDrive vs 718 Cayman S: chronicle of a drag race at 285 km/h
The launch: 0 to 100 km/h
Off the line, the 718 Cayman S hits 100 km/h in 4.17 s versus 4.63 s for the Bmw 750Ld xDrive. At this point, the 718 Cayman S leads by 0.46 s and sits roughly 3 m ahead.
From 100 km/h to 400 metres
At 200 metres, the 718 Cayman S is doing 156 km/h against 145 km/h for the Bmw 750Ld xDrive. The gap is 0.41 s. The gap remains stable from the start.
At 400 metres standing start, the 718 Cayman S crosses the line in 12.12 s versus 12.84 s. The 0.72 s gap represents roughly 35 m of track — a gap visible to the naked eye.
Beyond 400 metres: top speed comes into play
Past 400 metres, the 718 Cayman S continues to build its lead. At 600 metres, it runs at 215 km/h versus 203 km/h. At 1,000 metres, the 718 Cayman S finishes in 21.89 s versus 23.18 s, with a 1.28 s lead.
What the numbers don’t tell you
Both rivals are electronically governed, but not at the same level: the Bmw 750Ld xDrive is capped at 250 km/h, the 718 Cayman S at 285 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 (4.95 kg/hp vs 3.87 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 7.01 seconds. The 0.46 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Porsche 718 Cayman S has a clear edge over the Bmw 750Ld xDrive to 100 km/h. This difference is clearly noticeable in spirited driving and widens on standing starts.
