Off the line, the X6 M50i hits 100 km/h in 4.26 s versus 4.34 s for the X5 M50i. The 0.08 s gap is negligible: both vehicles are neck and neck.
At 200 metres, the X6 M50i is doing 154 km/h against 150 km/h for the X5 M50i. The gap is 0.06 s. The gap remains stable from the start.
At 400 metres standing start, the X6 M50i crosses the line in 12.29 s versus 12.43 s. The 0.14 s gap represents roughly 7 m of track - barely a car length.
Past 400 metres, the X6 M50i continues to build its lead. At 600 metres, it runs at 214 km/h versus 209 km/h. At 1,000 metres, the X6 M50i finishes in 22.14 s versus 22.50 s, with a 0.36 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 X5 M50i and the X6 M50i 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 (4.25 kg/hp vs 4.23 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 6.38 seconds. The 0.08 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, X5 M50i G05 and X6 M50i G06 are neck and neck (4,25 s vs 4,34 s, no significant gap).
X5 M50i G05 goes from 0 to 100 km/h in 4,34 seconds (calibrated simulation).
X5 M50i G05: 530 hp, ratio 4,25 kg/hp. X6 M50i G06: 530 hp, ratio 4,23 kg/hp.
X5 M50i G05: 250 km/h. X6 M50i G06: 250 km/h.
