Mercedes AMG C 63 S E PERFORMANCE W206 vs BMW M5 F90: which is truly faster?

Off the line, the AMG C 63 S E PERFORMANCE hits 100 km/h in 3.39 s versus 3.44 s for the Bmw M5. The instant torque of 1,020 Nm from the electric motor makes the difference. The 0.05 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 168 km/h for the Bmw M5. The gap is 0.07 s. The gap remains stable from the start.

At 400 metres standing start, the AMG C 63 S E PERFORMANCE crosses the line in 11.06 s versus 11.16 s. The 0.10 s gap represents roughly 6 m of track - barely a car length.

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 235 km/h. At 1,000 metres, the AMG C 63 S E PERFORMANCE finishes in 19.80 s versus 20.22 s, with a 0.42 s lead.

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 Bmw M5 at 250 (i.e. 155 mph - industry threshold) 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 4.88 seconds. The 0.05 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
