Off the line, the M140i xDrive hits 100 km/h in 4.43 s versus 5.31 s for the E 400 e 4MATIC. Despite lacking instant torque, 340 hp of power compensates. At this point, the M140i xDrive leads by 0.88 s and sits roughly 6 m ahead.
At 200 metres, the M140i xDrive is doing 147 km/h against 135 km/h for the E 400 e 4MATIC. The gap is 0.58 s. The challenger starts to claw back ground.
At 400 metres standing start, the M140i xDrive crosses the line in 12.64 s versus 13.57 s. The 0.93 s gap represents roughly 43 m of track - a gap visible to the naked eye.
Past 400 metres, the M140i xDrive continues to build its lead. At 600 metres, it runs at 203 km/h versus 190 km/h. At 1,000 metres, the M140i xDrive finishes in 23.01 s versus 24.58 s, with a 1.57 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 E 400 e 4MATIC and the M140i 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 8.31 seconds. The 0.88 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, M140i xDrive F20LCI wins (4,43 s vs 5,30 s).
