Off the line, the X6 M50i hits 100 km/h in 4.26 s versus 4.76 s for the X4 M40i. At this point, the X6 M50i leads by 0.50 s and sits roughly 3 m ahead.
At 200 metres, the X6 M50i is doing 154 km/h against 143 km/h for the X4 M40i. The gap is 0.38 s. The challenger starts to claw back ground.
At 400 metres standing start, the X6 M50i crosses the line in 12.29 s versus 12.99 s. The 0.70 s gap represents roughly 34 m of track - a gap visible to the naked eye.
Past 400 metres, the X6 M50i continues to build its lead. At 600 metres, it runs at 214 km/h versus 198 km/h. At 1,000 metres, the X6 M50i finishes in 22.14 s versus 23.60 s, with a 1.46 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 X6 M50i and the X4 M40i 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 5.16 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 7.22 seconds. The 0.50 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, X6 M50i G06 wins (4,25 s vs 4,75 s).
X6 M50i G06 goes from 0 to 100 km/h in 4,25 seconds (calibrated simulation).
