Xpeng G6 vs Porsche Macan GTS: which is truly faster?

Off the line, the G6 hits 100 km/h in 3.80 s versus 4.49 s for the Macan GTS. The instant torque of 660 Nm from the electric motor makes the difference. At this point, the G6 leads by 0.69 s and sits roughly 7 m ahead.

At 200 metres, the G6 is doing 152 km/h against 147 km/h for the Macan GTS. The gap is 0.47 s. The challenger starts to claw back ground.

At 400 metres standing start, the G6 crosses the line in 12.03 s versus 12.61 s. The 0.58 s gap represents roughly 29 m of track - two to three car lengths.

Past 400 metres, the situation changes. The G6 maxes out at 200 km/h while the Macan GTS keeps accelerating towards 272 km/h. At 600 metres, the gap has dropped to 0.61 s.

Around 963 metres, both vehicles are level. This is the inversion point: the Macan GTS overcomes its launch deficit thanks to a 72 km/h higher top speed.

At 1,000 metres, the Macan GTS finishes in 22.79 s versus 22.89 s. The 0.10 s delta shows an extremely tight race.

Both rivals are electronically governed, but not at the same level: the G6 is capped at 200 km/h, the Macan GTS at 272 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 6.65 seconds. The 0.69 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
