Mercedes Maybach S 680 vs Xpeng G6: which is truly faster?

Off the line, the G6 hits 100 km/h in 3.80 s versus 4.53 s for the Maybach S 680. The instant torque of 660 Nm from the electric motor makes the difference. At this point, the G6 leads by 0.73 s and sits roughly 9 m ahead.

At 200 metres, the G6 is doing 152 km/h against 153 km/h for the Maybach S 680. 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 12.41 s. The 0.38 s gap represents roughly 20 m of track - two to three car lengths.

Past 400 metres, the situation changes. The G6 maxes out at 200 km/h while the Maybach S 680 keeps accelerating towards 250 (i.e. 155 mph - industry threshold) km/h. At 600 metres, the gap has dropped to 0.20 s.

Around 700 metres, both vehicles are level. This is the inversion point: the Maybach S 680 overcomes its launch deficit thanks to a 50 km/h higher top speed.

At 1,000 metres, the Maybach S 680 finishes in 21.93 s versus 22.89 s. The 0.96 s delta in favour of the Maybach S 680 shows that top speed makes a clear difference.

Both rivals are electronically governed, but not at the same level: the Maybach S 680 is capped at 250 (i.e. 155 mph - industry threshold) km/h, the G6 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.

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 6.44 seconds. The 0.73 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
