CONFIDENCE 93%Why this result?
The Bmw 750Ld xDrive is faster at 0-100 km/h, but the Porsche 911 Carrera 4 (PDK) compensates at high speed thanks to higher peak power or top speed. At 400 m, Porsche 911 Carrera 4 (PDK) leads by 0.11 s.

Bmw 750Ld xDrive vs 911 Carrera 4 (PDK): chronicle of a drag race at 282 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 4.68 s for the 911 Carrera 4 (PDK). The 0.04 s gap is negligible: both vehicles are neck and neck.
From 100 km/h to 400 metres
At 200 metres, the Bmw 750Ld xDrive is doing 145 km/h against 149 km/h for the 911 Carrera 4 (PDK). The gap is 0.00 s. The gap remains stable from the start.
At 400 metres standing start, the 911 Carrera 4 (PDK) crosses the line in 12.72 s versus 12.84 s. The 0.12 s gap represents roughly 6 m of track — barely a car length.
Beyond 400 metres: top speed comes into play
Past 400 metres, the 911 Carrera 4 (PDK) continues to build its lead. At 600 metres, it runs at 207 km/h versus 203 km/h. At 1,000 metres, the 911 Carrera 4 (PDK) finishes in 22.87 s versus 23.18 s, with a 0.30 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 4 (PDK) at 282 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 4.29 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 0.04 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Bmw 750Ld xDrive and Porsche 911 Carrera 4 (PDK) 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.
