Mercedes AMG C 63 S E PERFORMANCE W206 vs Audi S e-tron GT: which is truly faster?

Off the line, the S e-tron GT hits 100 km/h in 3.36 s versus 3.39 s for the AMG C 63 S E PERFORMANCE. The 0.04 s gap is negligible: both vehicles are neck and neck.

At 200 metres, the AMG C 63 S E PERFORMANCE is doing 169 km/h against 158 km/h for the S e-tron GT. The gap is 0.13 s. The gap widens compared to the 0-100.

At 400 metres standing start, the AMG C 63 S E PERFORMANCE crosses the line in 11.06 s versus 11.50 s. The 0.44 s gap represents roughly 23 m of track - two to three car lengths.

Past 400 metres, the AMG C 63 S E PERFORMANCE continues to build its lead. At 600 metres, it runs at 240 km/h versus 219 km/h. At 1,000 metres, the AMG C 63 S E PERFORMANCE finishes in 19.80 s versus 21.11 s, with a 1.31 s lead.

On paper, the AMG C 63 S E PERFORMANCE combines 680 hp, 1,020 Nm and 2,165 kg - a clear theoretical edge over the S e-tron GT. Yet the S e-tron GT launches quicker. At standstill, both motors deliver peak torque from 0 rpm: the decisive factor is no longer raw power, but available grip. If the S e-tron GT has a better traction coefficient (tyres, weight distribution, traction control calibration), it puts down more force despite inferior specs - exactly what the simulation reflects, calibrated on manufacturer 0-100 km/h times.

Both rivals are electronically governed, but not at the same level: the AMG C 63 S E PERFORMANCE is capped at 280 km/h, the S e-tron GT at 245 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 (3.18 kg/hp vs 3.47 kg/hp) and transmission (Unknown vs Unknown).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 5.14 seconds. The 0.04 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
