Xpeng G9 vs BMW X7 xDrive30d G07: which is truly faster?

Off the line, the Bmw X7 xDrive30d hits 100 km/h in 6.94 s versus 8.51 s for the G9. Despite lacking instant torque, 265 hp of power compensates. At this point, the Bmw X7 xDrive30d leads by 1.57 s and sits roughly 35 m ahead.

At 200 metres, the Bmw X7 xDrive30d is doing 119 km/h against 120 km/h for the G9. The gap is 1.37 s. The challenger starts to claw back ground.

At 400 metres standing start, the Bmw X7 xDrive30d crosses the line in 15.04 s versus 16.32 s. The 1.27 s gap represents roughly 52 m of track - a gap visible to the naked eye.

Past 400 metres, the gap narrows. The G9 maxes out at 200 km/h while the Bmw X7 xDrive30d keeps accelerating towards 227 km/h. At 600 metres, the gap is down to 1.14 s from 1.27 s at 400 metres.

At 1,000 metres, the Bmw X7 xDrive30d finishes in 27.89 s versus 28.71 s, with just 0.81 s to spare. The G9 fails to fully close the launch gap.

The Bmw X7 xDrive30d 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 G9 is capped at 200 km/h, the Bmw X7 xDrive30d at 227 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 12.63 seconds. The 1.57 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
