CONFIDENCE 93%The Bmw 750Ld reaches 100 km/h first (4.63 s vs 4.77 s), but the 911 Carrera is ahead at every metre of the race. Explanation: the 911 Carrera accelerates harder at low speed and builds a distance gap before either car hits 100 km/h.
Why this result?
The Bmw 750Ld xDrive is faster at 0-100 km/h, but the Porsche 911 Carrera (Manual) compensates at high speed thanks to higher peak power or top speed. At 400 m, Porsche 911 Carrera (Manual) leads by 0.03 s.

Bmw 750Ld xDrive vs 911 Carrera (Manual): chronicle of a drag race at 289 km/h
The launch: 0 to 100 km/h
Off the line, the Bmw 750Ld xDrive hits 100 km/h in 4.63 s versus 4.77 s for the 911 Carrera (Manual). At this point, the Bmw 750Ld xDrive leads by 0.14 s and sits roughly 3 m ahead.
From 100 km/h to 400 metres
At 200 metres, the Bmw 750Ld xDrive is doing 145 km/h against 148 km/h for the 911 Carrera (Manual). The gap is 0.09 s. The gap remains stable from the start.
At 400 metres standing start, the 911 Carrera (Manual) crosses the line in 12.81 s versus 12.84 s. The 0.03 s gap represents roughly 2 m of track
Beyond 400 metres: top speed comes into play
Past 400 metres, the 911 Carrera (Manual) continues to build its lead. At 600 metres, it runs at 209 km/h versus 203 km/h. At 1,000 metres, the 911 Carrera (Manual) finishes in 22.88 s versus 23.18 s, with a 0.29 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 911 Carrera (Manual) at 289 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 4.13 kg/hp) and transmission (Automatic vs Manual).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 7.09 seconds. The 0.14 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Bmw 750Ld xDrive and Porsche 911 Carrera (Manual) are virtually tied to 100 km/h. The gap is under a tenth of a second — only the physics engine can settle it step by step.
