Mercedes AMG C 63 S E PERFORMANCE T-Modell W206 vs Xpeng P7: which is truly faster?

Off the line, the AMG C 63 S E PERFORMANCE T-Modell hits 100 km/h in 3.36 s versus 4.22 s for the P7. At this point, the AMG C 63 S E PERFORMANCE T-Modell leads by 0.86 s and sits roughly 8 m ahead.

At 200 metres, the AMG C 63 S E PERFORMANCE T-Modell is doing 169 km/h against 147 km/h for the P7. The gap is 0.85 s. The gap remains stable from the start.

At 400 metres standing start, the AMG C 63 S E PERFORMANCE T-Modell crosses the line in 11.02 s versus 12.54 s. The 1.53 s gap represents roughly 72 m of track - a gap visible to the naked eye.

Past 400 metres, the AMG C 63 S E PERFORMANCE T-Modell continues to build its lead. At 600 metres, it runs at 241 km/h versus 170 km/h. At 1,000 metres, the AMG C 63 S E PERFORMANCE T-Modell finishes in 19.73 s versus 25.24 s, with a 5.51 s lead.

Both rivals are electronically governed, but not at the same level: the AMG C 63 S E PERFORMANCE T-Modell is capped at 270 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.

With two plug-in hybrid powertrains, the difference comes down to power-to-weight ratio (3.22 kg/hp vs 4.81 kg/hp) and transmission (Unknown vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 6.49 seconds. The 0.86 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
