Off the line, the RS 5 Avant hits 100 km/h in 3.66 s versus 3.83 s for the M850i xDrive. The instant torque of 825 Nm from the electric motor makes the difference. At this point, the RS 5 Avant leads by 0.17 s and sits roughly 4 m ahead.
At 200 metres, the RS 5 Avant is doing 156 km/h against 160 km/h for the M850i xDrive. The gap is 0.10 s. The gap remains stable from the start.
At 400 metres standing start, the M850i xDrive crosses the line in 11.71 s versus 11.72 s. The 0.01 s gap represents roughly 1 m of track
Past 400 metres, the M850i xDrive continues to build its lead. At 600 metres, it runs at 224 km/h versus 218 km/h. At 1,000 metres, the M850i xDrive finishes in 21.07 s versus 21.35 s, with a 0.28 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 RS 5 Avant and the M850i xDrive 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.
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 5.51 seconds. The 0.17 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, RS 5 Avant wins (3,66 s vs 3,83 s).
RS 5 Avant goes from 0 to 100 km/h in 3,66 seconds (calibrated simulation).
