Off the line, the M340i xDrive hits 100 km/h in 4.32 s versus 4.45 s for the S 580 e 4MATIC. Despite lacking instant torque, 382 hp of power compensates. At this point, the M340i xDrive leads by 0.13 s and sits roughly 6 m ahead.
At 200 metres, the M340i xDrive is doing 147 km/h against 149 km/h for the S 580 e 4MATIC. The gap is 0.16 s. The gap remains stable from the start.
At 400 metres standing start, the M340i xDrive crosses the line in 12.46 s versus 12.54 s. The 0.08 s gap represents roughly 4 m of track - barely a car length.
Past 400 metres, the situation changes. Past 400 metres, both rivals hit the same electronic ceiling at 250 (i.e. 155 mph - industry threshold) km/h. Neither can claw back ground through top speed - the outcome hinges on the acceleration curve between 100 and 250 (i.e. 155 mph - industry threshold) km/h.
At 1,000 metres, the S 580 e 4MATIC finishes in 22.40 s versus 22.65 s. The 0.25 s delta shows an extremely tight race.
Both rivals share the same electronic speed cap: the S 580 e 4MATIC and the M340i xDrive 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 6.58 seconds. The 0.13 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Swap one of the two models to explore an equivalent duel in the same segment.
