Porsche 2013 Panamera GTS 970.1 vs Xpeng P7: which is truly faster?

Off the line, the P7 hits 100 km/h in 4.22 s versus 4.48 s for the 2013 Panamera GTS. The instant torque of 655 Nm from the electric motor makes the difference. At this point, the P7 leads by 0.26 s and sits roughly 4 m ahead.

At 200 metres, the P7 is doing 147 km/h against 147 km/h for the 2013 Panamera GTS. The gap is 0.21 s. The gap remains stable from the start.

At 400 metres standing start, the P7 crosses the line in 12.54 s versus 12.69 s. The 0.14 s gap represents roughly 7 m of track - barely a car length.

Past 400 metres, the situation changes. The P7 maxes out at 170 km/h while the 2013 Panamera GTS keeps accelerating towards 280 km/h. At 600 metres, the gap has dropped to 0.37 s.

Around 477 metres, both vehicles are level. This is the inversion point: the 2013 Panamera GTS overcomes its launch deficit thanks to a 110 km/h higher top speed.

At 1,000 metres, the 2013 Panamera GTS finishes in 22.94 s versus 25.24 s. The 2.30 s delta in favour of the 2013 Panamera GTS shows that top speed makes a clear difference.

Both rivals are electronically governed, but not at the same level: the 2013 Panamera GTS is capped at 288 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 6.84 seconds. The 0.26 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
