Off the line, the X4 M40d hits 100 km/h in 4.94 s versus 5.59 s for the X6 xDrive40d. At this point, the X4 M40d leads by 0.64 s and sits roughly 6 m ahead.
At 200 metres, the X4 M40d is doing 137 km/h against 131 km/h for the X6 xDrive40d. The gap is 0.41 s. The challenger starts to claw back ground.
At 400 metres standing start, the X4 M40d crosses the line in 13.29 s versus 13.91 s. The 0.62 s gap represents roughly 28 m of track - two to three car lengths.
Past 400 metres, the X4 M40d continues to build its lead. At 600 metres, it runs at 190 km/h versus 182 km/h. At 1,000 metres, the X4 M40d finishes in 24.38 s versus 25.48 s, with a 1.10 s lead. Both vehicles have similar top speeds (248 vs 250 (i.e. 155 mph - industry threshold) km/h), preventing any comeback.
Both rivals share the same electronic speed cap: the X6 xDrive40d and the X4 M40d are governed to 248 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 (6.51 kg/hp vs 5.81 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 8.87 seconds. The 0.64 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
