Audi A6 Avant e-tron quattro 315 kW vs Xpeng P7i: which is truly faster?

Off the line, the A6 Avant e-tron quattro 315 kW hits 100 km/h in 4.45 s versus 6.31 s for the P7i. At this point, the A6 Avant e-tron quattro 315 kW leads by 1.86 s and sits roughly 19 m ahead.

At 200 metres, the A6 Avant e-tron quattro 315 kW is doing 143 km/h against 129 km/h for the P7i. The gap is 1.28 s. The challenger starts to claw back ground.

At 400 metres standing start, the A6 Avant e-tron quattro 315 kW crosses the line in 12.80 s versus 14.56 s. The 1.77 s gap represents roughly 75 m of track - a gap visible to the naked eye.

Past 400 metres, the A6 Avant e-tron quattro 315 kW continues to build its lead. At 600 metres, it runs at 197 km/h versus 178 km/h. At 1,000 metres, the A6 Avant e-tron quattro 315 kW finishes in 23.59 s versus 26.38 s, with a 2.78 s lead. Both vehicles have similar top speeds (210 vs 200 km/h), preventing any comeback.

The A6 Avant e-tron quattro 315 kW 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 A6 Avant e-tron quattro 315 kW is capped at 210 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.

With two electric powertrains, the difference comes down to power-to-weight ratio (5.36 kg/hp vs 7.18 kg/hp) and transmission (Unknown vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 9.78 seconds. The 1.86 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
