Off the line, the X3 M40i hits 100 km/h in 4.74 s versus 4.87 s for the S 580 e 4MATIC. Despite lacking instant torque, 360 hp of power compensates. At this point, the X3 M40i leads by 0.13 s and sits roughly 3 m ahead.
At 200 metres, the X3 M40i is doing 142 km/h against 144 km/h for the S 580 e 4MATIC. The gap is 0.06 s. The gap remains stable from the start.
At 400 metres standing start, the S 580 e 4MATIC crosses the line in 12.95 s versus 12.98 s. The 0.02 s gap represents roughly 1 m of track
Past 400 metres, the S 580 e 4MATIC continues to build its lead. At 600 metres, it runs at 206 km/h versus 198 km/h. At 1,000 metres, the S 580 e 4MATIC finishes in 23.10 s versus 23.62 s, with a 0.52 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.
Both rivals share the same electronic speed cap: the S 580 e 4MATIC 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 0.13 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, X3 M40i G01 wins (4,74 s vs 4,87 s).
S 580 e 4MATIC W223 goes from 0 to 100 km/h in 4,87 seconds (calibrated simulation).
