Porsche Panamera 970.1 vs Xpeng P7: which is truly faster?

Off the line, the Panamera hits 100 km/h in 5.83 s versus 6.58 s for the P7. Despite lacking instant torque, 304 hp of power compensates. At this point, the Panamera leads by 0.75 s and sits roughly 11 m ahead.

At 200 metres, the Panamera is doing 130 km/h against 127 km/h for the P7. The gap is 0.51 s. The challenger starts to claw back ground.

At 400 metres standing start, the Panamera crosses the line in 14.15 s versus 14.81 s. The 0.66 s gap represents roughly 29 m of track - two to three car lengths.

Past 400 metres, the Panamera continues to build its lead. At 600 metres, it runs at 181 km/h versus 170 km/h. At 1,000 metres, the Panamera finishes in 25.76 s versus 27.64 s, with a 1.88 s lead.

Both rivals are electronically governed, but not at the same level: the Panamera is capped at 257 km/h, the P7 at 170 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 10.18 seconds. The 0.75 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
