Off the line, the Bmw X3 M40d hits 100 km/h in 4.87 s versus 4.94 s for the Bmw X4 M40d. The 0.07 s gap is negligible: both vehicles are neck and neck.
At 200 metres, the Bmw X3 M40d is doing 138 km/h against 137 km/h for the Bmw X4 M40d. The gap is 0.04 s. The gap remains stable from the start.
At 400 metres standing start, the Bmw X3 M40d crosses the line in 13.21 s versus 13.29 s. The 0.07 s gap represents roughly 4 m of track - barely a car length.
Past 400 metres, nothing changes. Same ceiling, same acceleration, same trajectory - both rivals run in formation to the line. The 0.14 s gap at 1,000 metres confirms what the specs already suggested: on track, they’re interchangeable. The real contest happens elsewhere - range, comfort, charging network reliability.
Both rivals share the same electronic speed cap: the Bmw X3 M40d and the Bmw 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 (5.81 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 7.77 seconds. The 0.07 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Swap one of the two models to explore an equivalent duel in the same segment.
