Off the line, the X7 M50i hits 100 km/h in 4.74 s versus 4.78 s for the X3 M40i. The 0.04 s gap is negligible: both vehicles are neck and neck.
At 200 metres, the X7 M50i is doing 144 km/h against 142 km/h for the X3 M40i. The gap is 0.03 s. The gap remains stable from the start.
At 400 metres standing start, the X7 M50i crosses the line in 12.92 s versus 13.02 s. The 0.10 s gap represents roughly 5 m of track - barely a car length.
Past 400 metres, the X7 M50i continues to build its lead. At 600 metres, it runs at 201 km/h versus 197 km/h. At 1,000 metres, the X7 M50i finishes in 23.38 s versus 23.67 s, with a 0.30 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 X7 M50i and the X3 M40i 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 (4.70 kg/hp vs 5.13 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 7.26 seconds. The 0.04 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, X7 M50i G07 and X3 M40i G01 are neck and neck (4,74 s vs 4,78 s, no significant gap).
X7 M50i G07 goes from 0 to 100 km/h in 4,74 seconds (calibrated simulation).
