Off the line, the Bmw M140i hits 100 km/h in 4.54 s versus 5.33 s for the Bmw X7 xDrive50i. At this point, the Bmw M140i leads by 0.79 s and sits roughly 4 m ahead.
At 200 metres, the Bmw M140i is doing 151 km/h against 137 km/h for the Bmw X7 xDrive50i. The gap is 0.53 s. The challenger starts to claw back ground.
At 400 metres standing start, the Bmw M140i crosses the line in 12.60 s versus 13.57 s. The 0.97 s gap represents roughly 45 m of track - a gap visible to the naked eye.
Past 400 metres, the Bmw M140i continues to build its lead. At 600 metres, it runs at 210 km/h versus 190 km/h. At 1,000 metres, the Bmw M140i finishes in 22.65 s versus 24.64 s, with a 1.99 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 X7 xDrive50i 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 (5.32 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 8.16 seconds. The 0.79 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 5,33 s).
