Off the line, the Model S P100D hits 100 km/h in 2.85 s versus 3.83 s for the M850i xDrive. The instant torque of 967 Nm from the electric motor makes the difference. At this point, the Model S P100D leads by 0.98 s and sits roughly 9 m ahead.
At 200 metres, the Model S P100D is doing 173 km/h against 160 km/h for the M850i xDrive. The gap is 0.82 s. The challenger starts to claw back ground.
At 400 metres standing start, the Model S P100D crosses the line in 10.63 s versus 11.71 s. The 1.08 s gap represents roughly 59 m of track - a gap visible to the naked eye.
Past 400 metres, the Model S P100D continues to build its lead. At 600 metres, it runs at 240 km/h versus 224 km/h. At 1,000 metres, the Model S P100D finishes in 19.59 s versus 21.07 s, with a 1.48 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 S P100D and the 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 5.50 seconds. The 0.98 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, Model S P100D wins (2,85 s vs 3,83 s).
Model S P100D goes from 0 to 100 km/h in 2,85 seconds (calibrated simulation).
