Panamera S vs Bmw 740Ld xDrive: chronicle of a drag race at 277 km/h
The launch: 0 to 100 km/h
Off the line, the Bmw 740Ld xDrive hits 100 km/h in 5.01 s versus 5.16 s for the Panamera S. At this point, the Bmw 740Ld xDrive leads by 0.15 s and sits roughly 6 m ahead.
From 100 km/h to 400 metres
At 200 metres, the Bmw 740Ld xDrive is doing 137 km/h against 140 km/h for the Panamera S. The gap is 0.15 s. The gap remains stable from the start.
At 400 metres standing start, the Bmw 740Ld xDrive crosses the line in 13.31 s versus 13.31 s. The 0.00 s gap represents roughly 0 m of track
Beyond 400 metres: top speed comes into play
Past 400 metres, the situation changes. The Bmw 740Ld xDrive maxes out at 250 km/h while the Panamera S keeps accelerating towards 277 km/h. At 600 metres, the gap has dropped to 0.10 s.
Around 407 metres, both vehicles are level. This is the inversion point: the Panamera S overcomes its launch deficit thanks to a 27 km/h higher top speed.
At 1,000 metres, the Panamera S finishes in 23.98 s versus 24.26 s. The 0.28 s delta shows an extremely tight race.
What the numbers don’t tell you
Both rivals are electronically governed, but not at the same level: the Panamera S is capped at 283 km/h, the Bmw 740Ld 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 (4.43 kg/hp vs 5.88 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 7.85 seconds. The 0.15 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Porsche Panamera S and Bmw 740Ld xDrive 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.
