Off the line, the Bmw 540d xDrive Touring hits 100 km/h in 4.84 s versus 4.94 s for the Bmw X4 M40d. At this point, the Bmw 540d xDrive Touring leads by 0.10 s and sits roughly 2 m ahead.
At 200 metres, the Bmw 540d xDrive Touring is doing 138 km/h against 137 km/h for the Bmw X4 M40d. The gap is 0.08 s. The gap remains stable from the start.
At 400 metres standing start, the Bmw 540d xDrive Touring crosses the line in 13.17 s versus 13.29 s. The 0.11 s gap represents roughly 5 m of track - barely a car length.
Past 400 metres, the Bmw 540d xDrive Touring continues to build its lead. At 600 metres, it runs at 192 km/h versus 190 km/h. At 1,000 metres, the Bmw 540d xDrive Touring finishes in 24.12 s versus 24.38 s, with a 0.26 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 X4 M40d and the Bmw 540d xDrive Touring 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 5.77 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 0.10 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, 540d xDrive Touring G30 wins (4,84 s vs 4,94 s).
X4 M40d G02 goes from 0 to 100 km/h in 4,94 seconds (calibrated simulation).
