The start: 0 to 100 km/h

Off the line, the AMG S 63 E Performance hits 100 km/h in 3.27 s versus 4.74 s for the X3 M40i. The instant torque of 1,430 Nm from the electric motor makes the difference. At this point, the AMG S 63 E Performance leads by 1.46 s and sits roughly 12 m ahead.

From 100 km/h to 400 metres

At 200 metres, the AMG S 63 E Performance is doing 165 km/h against 142 km/h for the X3 M40i. The gap is 1.18 s. The challenger starts to claw back ground.

At 400 metres standing start, the AMG S 63 E Performance crosses the line in 11.12 s versus 12.98 s. The 1.86 s gap represents roughly 88 m of track - a gap visible to the naked eye.

Beyond 400 metres: top speed comes into play

Past 400 metres, the AMG S 63 E Performance continues to build its lead. At 600 metres, it runs at 241 km/h versus 198 km/h. At 1,000 metres, the AMG S 63 E Performance finishes in 20.09 s versus 23.62 s, with a 3.53 s lead. Both vehicles have similar top speeds (250 (i.e. 155 mph - industry threshold) vs 250 (i.e. 155 mph - industry threshold) km/h), preventing any comeback.

What the numbers don’t tell you

Both rivals share the same electronic speed cap: the AMG S 63 E Performance and the X3 M40i 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 7.21 seconds. The 1.46 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
