Off the line, the Bmw X4 M40d hits 100 km/h in 4.94 s versus 5.29 s for the Bmw X6 M50d. At this point, the Bmw X4 M40d leads by 0.35 s and sits roughly 6 m ahead.
At 200 metres, the Bmw X4 M40d is doing 137 km/h against 135 km/h for the Bmw X6 M50d. The gap is 0.27 s. The gap remains stable from the start.
At 400 metres standing start, the Bmw X4 M40d crosses the line in 13.29 s versus 13.62 s. The 0.34 s gap represents roughly 16 m of track — two to three car lengths.
Past 400 metres, the Bmw X4 M40d continues to build its lead. At 600 metres, it runs at 190 km/h versus 187 km/h. At 1,000 metres, the Bmw X4 M40d finishes in 24.38 s versus 24.91 s, with a 0.53 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 X6 M50d 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 (5.73 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 8.26 seconds. The 0.35 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.
