Panamera S vs Bmw M340d xDrive: chronicle of a drag race at 276 km/h
The launch: 0 to 100 km/h
Off the line, the Bmw M340d xDrive hits 100 km/h in 4.57 s versus 5.19 s for the Panamera S. At this point, the Bmw M340d xDrive leads by 0.62 s and sits roughly 13 m ahead.
From 100 km/h to 400 metres
At 200 metres, the Bmw M340d xDrive is doing 140 km/h against 140 km/h for the Panamera S. The gap is 0.52 s. The challenger starts to claw back ground.
At 400 metres standing start, the Bmw M340d xDrive crosses the line in 12.86 s versus 13.35 s. The 0.49 s gap represents roughly 24 m of track — two to three car lengths.
Beyond 400 metres: top speed comes into play
Past 400 metres, the Bmw M340d xDrive continues to build its lead. At 600 metres, it runs at 197 km/h versus 196 km/h. At 1,000 metres, the Bmw M340d xDrive finishes in 23.52 s versus 24.06 s, with a 0.54 s lead. Despite a higher top speed (276 km/h), the Panamera S never recovers its launch deficit.
What the numbers don’t tell you
The Bmw M340d xDrive 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 282 km/h, the Bmw M340d 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 5.61 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 7.78 seconds. The 0.62 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Bmw M340d xDrive has a clear edge over the Porsche Panamera S to 100 km/h. This difference is clearly noticeable in spirited driving and widens on standing starts.
