Xpeng P7 vs BMW M240i F44: which is truly faster?

Off the line, the P7 hits 100 km/h in 4.22 s versus 4.67 s for the M240i. The instant torque of 655 Nm from the electric motor makes the difference. At this point, the P7 leads by 0.45 s and sits roughly 8 m ahead.

At 200 metres, the P7 is doing 147 km/h against 147 km/h for the M240i. The gap is 0.33 s. The challenger starts to claw back ground.

At 400 metres standing start, the P7 crosses the line in 12.54 s versus 12.78 s. The 0.23 s gap represents roughly 12 m of track - two to three car lengths.

Past 400 metres, the situation changes. The P7 maxes out at 170 km/h while the M240i keeps accelerating towards 250 (i.e. 155 mph - industry threshold) km/h. At 600 metres, the gap has dropped to 0.30 s.

Around 506 metres, both vehicles are level. This is the inversion point: the M240i overcomes its launch deficit thanks to a 80 km/h higher top speed.

At 1,000 metres, the M240i finishes in 23.03 s versus 25.24 s. The 2.22 s delta in favour of the M240i shows that top speed makes a clear difference.

The P7 features all-wheel drive (AWD) against the M240i’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 P7 is capped at 170 km/h, the M240i 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.

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 6.84 seconds. The 0.45 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
