Porsche Panamera S 970.1 vs BMW 540d xDrive Touring G30: which is truly faster?

Off the line, the Bmw 540d xDrive Touring hits 100 km/h in 4.71 s versus 5.16 s for the Panamera S. At this point, the Bmw 540d xDrive Touring leads by 0.45 s and sits roughly 9 m ahead.

At 200 metres, the Bmw 540d xDrive Touring is doing 141 km/h against 140 km/h for the Panamera S. The gap is 0.35 s. The gap remains stable from the start.

At 400 metres standing start, the Bmw 540d xDrive Touring crosses the line in 12.99 s versus 13.31 s. The 0.32 s gap represents roughly 16 m of track — two to three car lengths.

Past 400 metres, the Bmw 540d xDrive Touring continues to build its lead. At 600 metres, it runs at 197 km/h versus 197 km/h. At 1,000 metres, the Bmw 540d xDrive Touring finishes in 23.67 s versus 23.98 s, with a 0.31 s lead. Despite a higher top speed (277 km/h), the Panamera S never recovers its launch deficit.

The Bmw 540d xDrive Touring features all-wheel drive (AWD) against the Panamera S’s RWD. At low speeds (0-30, 0-50, 0-80 km/h), AWD doubles the driven contact area: all four wheels transmit torque to the road, virtually eliminating wheelspin at launch. This traction advantage is decisive in the range where the motor delivers peak torque, before power and aerodynamics take over.

Both rivals are electronically governed, but not at the same level: the Panamera S is capped at 283 km/h, the Bmw 540d xDrive Touring 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 (4.43 kg/hp vs 5.66 kg/hp) and transmission (Automatic vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 7.71 seconds. The 0.45 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
