Bmw 540i xDrive Touring vs P7i: chronicle of a drag race at 250 km/h
The launch: 0 to 100 km/h
Off the line, the Bmw 540i xDrive Touring hits 100 km/h in 5.14 s versus 6.31 s for the P7i. Despite lacking instant torque, 333 hp of power compensates. At this point, the Bmw 540i xDrive Touring leads by 1.17 s and sits roughly 16 m ahead.
From 100 km/h to 400 metres
At 200 metres, the Bmw 540i xDrive Touring is doing 138 km/h against 129 km/h for the P7i. The gap is 0.87 s. The challenger starts to claw back ground.
At 400 metres standing start, the Bmw 540i xDrive Touring crosses the line in 13.34 s versus 14.56 s. The 1.23 s gap represents roughly 53 m of track — a gap visible to the naked eye.
Beyond 400 metres: top speed comes into play
Past 400 metres, the Bmw 540i xDrive Touring continues to build its lead. At 600 metres, it runs at 190 km/h versus 178 km/h. At 1,000 metres, the Bmw 540i xDrive Touring finishes in 24.32 s versus 26.38 s, with a 2.06 s lead.
What the numbers don’t tell you
The Bmw 540i xDrive Touring features all-wheel drive (AWD) against the P7i’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 Bmw 540i xDrive Touring is capped at 250 km/h, the P7i at 200 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.
Instant electric torque gives an advantage off the line. The higher top speed of the combustion engine gives an advantage over longer distances. The distance at which one catches the other depends on the top speed differential.
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 9.78 seconds. The 1.17 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Bmw 540i xDrive Touring has a clear edge over the Xpeng P7i to 100 km/h. This difference is clearly noticeable in spirited driving and widens on standing starts.
