Off the line, the Bmw M140i hits 100 km/h in 4.54 s versus 4.75 s for the Bmw 540i xDrive. The 0.21 s gap is negligible: both vehicles are neck and neck.
At 200 metres, the Bmw M140i is doing 151 km/h against 145 km/h for the Bmw 540i xDrive. The gap is 0.14 s. The gap remains stable from the start.
At 400 metres standing start, the Bmw M140i crosses the line in 12.60 s versus 12.90 s. The 0.30 s gap represents roughly 15 m of track - two to three car lengths.
Past 400 metres, the Bmw M140i continues to build its lead. At 600 metres, it runs at 210 km/h versus 203 km/h. At 1,000 metres, the Bmw M140i finishes in 22.65 s versus 23.22 s, with a 0.58 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 Bmw 540i xDrive 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.
With two combustion powertrains, the difference comes down to power-to-weight ratio (4.88 kg/hp vs 4.32 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 0.21 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, M140i F20LCI wins (4,54 s vs 4,75 s).
