Mercedes AMG S 63 E Performance W223 vs BMW M5 Competition F90: which is truly faster?

Off the line, the AMG S 63 E Performance hits 100 km/h in 3.27 s versus 3.33 s for the Bmw M5 Competition. The instant torque of 1,430 Nm from the electric motor makes the difference. The 0.06 s gap is negligible: both vehicles are neck and neck.

At 200 metres, the Bmw M5 Competition is doing 168 km/h against 165 km/h for the AMG S 63 E Performance. The gap is 0.01 s. The gap remains stable from the start.

At 400 metres standing start, the Bmw M5 Competition crosses the line in 11.11 s versus 11.12 s. The 0.02 s gap represents roughly 1 m of track

Past 400 metres, nothing changes. Same ceiling, same acceleration, same trajectory - both rivals run in formation to the line. The 0.12 s gap at 1,000 metres confirms what the specs already suggested: on track, they’re interchangeable. The real contest happens elsewhere - range, comfort, charging network reliability.

Both rivals share the same electronic speed cap: the AMG S 63 E Performance and the Bmw M5 Competition are governed to 250 (i.e. 155 mph - industry threshold) km/h. At that speed, standard-fit tyres approach their safety threshold - an industrial ceiling common to most electric vehicles in this segment. Neither car shows its true aerodynamic potential in this duel.

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 4.89 seconds. The 0.06 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
