Off the line, the X3 M40i hits 100 km/h in 4.74 s versus 4.81 s for the X4 M40d. The 0.07 s gap is negligible: both vehicles are neck and neck.
At 200 metres, the X3 M40i is doing 142 km/h against 139 km/h for the X4 M40d. The gap is 0.03 s. The gap remains stable from the start.
At 400 metres standing start, the X3 M40i crosses the line in 12.98 s versus 13.13 s. The 0.15 s gap represents roughly 7 m of track - barely a car length.
Past 400 metres, the X3 M40i continues to build its lead. At 600 metres, it runs at 198 km/h versus 193 km/h. At 1,000 metres, the X3 M40i finishes in 23.62 s versus 24.04 s, with a 0.42 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 X3 M40i and the X4 M40d 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 (5.19 kg/hp vs 5.94 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 7.54 seconds. The 0.07 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, X3 M40i G01 and X4 M40d G02 are neck and neck (4,74 s vs 4,81 s, no significant gap).
X3 M40i G01 goes from 0 to 100 km/h in 4,74 seconds (calibrated simulation).
X3 M40i G01: 360 hp, ratio 5,19 kg/hp. X4 M40d G02: 340 hp, ratio 5,94 kg/hp.
X3 M40i G01: 250 km/h. X4 M40d G02: 250 km/h.
