The start: 0 to 100 km/h

Off the line, the Bmw 740d xDrive hits 100 km/h in 5.16 s versus 5.45 s for the Panamera 4. At this point, the Bmw 740d xDrive leads by 0.29 s and sits roughly 2 m ahead.

From 100 km/h to 400 metres

At 200 metres, the Bmw 740d xDrive is doing 136 km/h against 132 km/h for the Panamera 4. The gap is 0.18 s. The challenger starts to claw back ground.

At 400 metres standing start, the Bmw 740d xDrive crosses the line in 13.47 s versus 13.78 s. The 0.31 s gap represents roughly 14 m of track — two to three car lengths.

Beyond 400 metres: top speed comes into play

Past 400 metres, the Bmw 740d xDrive continues to build its lead. At 600 metres, it runs at 190 km/h versus 184 km/h. At 1,000 metres, the Bmw 740d xDrive finishes in 24.53 s versus 25.22 s, with a 0.69 s lead. Both vehicles have similar top speeds (257 vs 250 (i.e. 155 mph — industry threshold) km/h), preventing any comeback.

What the numbers don’t tell you

Both rivals are electronically governed, but not at the same level: the Panamera 4 is capped at 257 km/h, the Bmw 740d xDrive at 250 (i.e. 155 mph — industry threshold) 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 (6.08 kg/hp vs 5.84 kg/hp) and transmission (Automatic vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 8.74 seconds. The 0.29 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
