Off the line, the Bmw M850i xDrive hits 100 km/h in 3.83 s versus 4.30 s for the Model X Long Range. Despite lacking instant torque, 530 hp of power compensates. At this point, the Bmw M850i xDrive leads by 0.46 s and sits roughly 8 m ahead.
At 200 metres, the Bmw M850i xDrive is doing 160 km/h against 158 km/h for the Model X Long Range. The gap is 0.36 s. The challenger starts to claw back ground.
At 400 metres standing start, the Bmw M850i xDrive crosses the line in 11.71 s versus 12.14 s. The 0.44 s gap represents roughly 24 m of track - two to three car lengths.
Past 400 metres, the Bmw M850i xDrive continues to build its lead. At 600 metres, it runs at 224 km/h versus 221 km/h. At 1,000 metres, the Bmw M850i xDrive finishes in 21.07 s versus 21.65 s, with a 0.57 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 Model X Long Range and the Bmw M850i xDrive are governed to 249 (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.
Instant electric torque gives an advantage off the line. The higher top speed of the combustion engine gives an advantage over longer distances. The distance at which one catches the other depends on the top speed differential.
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 5.92 seconds. The 0.46 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 4,29 s).
Model X Long Range goes from 0 to 100 km/h in 4,29 seconds (calibrated simulation).
