Xpeng P7 vs Xpeng G9: which is truly faster?

Off the line, the P7 hits 100 km/h in 4.22 s versus 8.51 s for the G9. At this point, the P7 leads by 4.30 s and sits roughly 33 m ahead.

At 200 metres, the P7 is doing 147 km/h against 120 km/h for the G9. The gap is 2.89 s. The challenger starts to claw back ground.

At 400 metres standing start, the P7 crosses the line in 12.54 s versus 16.32 s. The 3.77 s gap represents roughly 147 m of track - a gap visible to the naked eye.

Past 400 metres, the gap narrows. The P7 maxes out at 170 km/h while the G9 keeps accelerating towards 200 km/h. At 600 metres, the gap is down to 4.04 s from 3.77 s at 400 metres.

At 1,000 metres, the P7 finishes in 25.24 s versus 28.71 s, with just 3.46 s to spare. The G9 fails to fully close the launch gap.

The P7 features all-wheel drive (AWD) against the G9’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 G9 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.

With two electric powertrains, the difference comes down to power-to-weight ratio (4.81 kg/hp vs 7.18 kg/hp) and transmission (Automatic vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 12.63 seconds. The 4.30 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
