Off the line, the M140i xDrive hits 100 km/h in 4.43 s versus 4.75 s for the 540i xDrive. At this point, the M140i xDrive leads by 0.32 s and sits roughly 4 m ahead.
At 200 metres, the M140i xDrive is doing 147 km/h against 145 km/h for the 540i xDrive. The gap is 0.23 s. The gap remains stable from the start.
At 400 metres standing start, the M140i xDrive crosses the line in 12.64 s versus 12.90 s. The 0.26 s gap represents roughly 13 m of track - two to three car lengths.
Past 400 metres, the M140i xDrive continues to build its lead. At 600 metres, it runs at 203 km/h versus 203 km/h. At 1,000 metres, the M140i xDrive finishes in 23.01 s versus 23.22 s, with a 0.21 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 540i xDrive 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.
With two combustion powertrains, the difference comes down to power-to-weight ratio (4.88 kg/hp vs 4.53 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 7.06 seconds. The 0.32 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 4,75 s).
540i xDrive G30 goes from 0 to 100 km/h in 4,75 seconds (calibrated simulation).
