Off the line, the X4 M Competition hits 100 km/h in 4.13 s versus 4.26 s for the X6 M50i. At this point, the X4 M Competition leads by 0.13 s and sits roughly 6 m ahead.
At 200 metres, the X4 M Competition is doing 151 km/h against 154 km/h for the X6 M50i. The gap is 0.15 s. The gap remains stable from the start.
At 400 metres standing start, the X4 M Competition crosses the line in 12.22 s versus 12.29 s. The 0.08 s gap represents roughly 4 m of track - barely a car length.
Past 400 metres, the situation changes. Past 400 metres, both rivals hit the same electronic ceiling at 250 (i.e. 155 mph - industry threshold) km/h. Neither can claw back ground through top speed - the outcome hinges on the acceleration curve between 100 and 250 (i.e. 155 mph - industry threshold) km/h.
At 1,000 metres, the X6 M50i finishes in 22.14 s versus 22.35 s. The 0.21 s delta shows an extremely tight race.
Both rivals share the same electronic speed cap: the X6 M50i and the X4 M Competition 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 (4.23 kg/hp vs 3.91 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 6.19 seconds. The 0.13 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, X4 M Competition G02 wins (4,13 s vs 4,25 s).
X6 M50i G06 goes from 0 to 100 km/h in 4,25 seconds (calibrated simulation).
X6 M50i G06: 530 hp, ratio 4,23 kg/hp. X4 M Competition G02: 510 hp, ratio 3,91 kg/hp.
X6 M50i G06: 250 km/h. X4 M Competition G02: 250 km/h.
