Off the line, the S 580 e 4MATIC hits 100 km/h in 4.45 s versus 4.54 s for the Bmw M140i. The instant torque of 750 Nm from the electric motor makes the difference. The 0.09 s gap is negligible: both vehicles are neck and neck.
At 200 metres, the S 580 e 4MATIC is doing 149 km/h against 151 km/h for the Bmw M140i. The gap is 0.09 s. The gap remains stable from the start.
At 400 metres standing start, the S 580 e 4MATIC crosses the line in 12.54 s versus 12.60 s. The 0.06 s gap represents roughly 3 m of track - barely a car length.
Past 400 metres, the S 580 e 4MATIC continues to build its lead. At 600 metres, it runs at 212 km/h versus 210 km/h. At 1,000 metres, the S 580 e 4MATIC finishes in 22.40 s versus 22.65 s, with a 0.25 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 Bmw M140i 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 6.56 seconds. The 0.09 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, S 580 e 4MATIC W223 and M140i F20LCI are neck and neck (4,45 s vs 4,54 s, no significant gap).
S 580 e 4MATIC W223 goes from 0 to 100 km/h in 4,45 seconds (calibrated simulation).
