Bmw 750Ld xDrive vs 911 Carrera 4 (Manual): chronicle of a drag race at 284 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 4.86 s for the 911 Carrera 4 (Manual). At this point, the Bmw 750Ld xDrive leads by 0.23 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 144 km/h for the 911 Carrera 4 (Manual). The gap is 0.15 s. The gap remains stable from the start.
At 400 metres standing start, the Bmw 750Ld xDrive crosses the line in 12.84 s versus 12.96 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 gap narrows. The Bmw 750Ld xDrive maxes out at 250 km/h while the 911 Carrera 4 (Manual) keeps accelerating towards 284 km/h. At 600 metres, the gap has dropped to 0.08 s.
At 1,000 metres, the Bmw 750Ld xDrive finishes in 23.18 s versus 23.25 s, with just 0.07 s to spare. The 911 Carrera 4 (Manual) fails to fully close the launch gap.
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 (Manual) at 284 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 4.43 kg/hp) and transmission (Automatic vs Manual).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 7.34 seconds. The 0.23 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Bmw 750Ld xDrive is slightly faster than the Porsche 911 Carrera 4 (Manual) to 100 km/h. The edge holds on standing starts but may narrow at higher speeds depending on aerodynamic load.
