Off the line, the M850i xDrive hits 100 km/h in 3.83 s versus 5.15 s for the X5 M50d. At this point, the M850i xDrive leads by 1.32 s and sits roughly 10 m ahead.
At 200 metres, the M850i xDrive is doing 160 km/h against 136 km/h for the X5 M50d. The gap is 1.05 s. The challenger starts to claw back ground.
At 400 metres standing start, the M850i xDrive crosses the line in 11.71 s versus 13.47 s. The 1.77 s gap represents roughly 80 m of track - a gap visible to the naked eye.
Past 400 metres, the M850i xDrive continues to build its lead. At 600 metres, it runs at 224 km/h versus 189 km/h. At 1,000 metres, the M850i xDrive finishes in 21.07 s versus 24.60 s, with a 3.53 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 M850i xDrive and the X5 M50d 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 (3.64 kg/hp vs 5.69 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 8.07 seconds. The 1.32 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, M850i xDrive G15 wins (3,83 s vs 5,15 s).
M850i xDrive G15 goes from 0 to 100 km/h in 3,83 seconds (calibrated simulation).
