Off the line, the RS e-tron GT hits 100 km/h in 3.33 s versus 4.34 s for the X5 M50i. The instant torque of 830 Nm from the electric motor makes the difference. At this point, the RS e-tron GT leads by 1.01 s and sits roughly 10 m ahead.
At 200 metres, the RS e-tron GT is doing 163 km/h against 150 km/h for the X5 M50i. The gap is 0.81 s. The challenger starts to claw back ground.
At 400 metres standing start, the RS e-tron GT crosses the line in 11.31 s versus 12.43 s. The 1.12 s gap represents roughly 57 m of track - a gap visible to the naked eye.
Past 400 metres, the RS e-tron GT continues to build its lead. At 600 metres, it runs at 227 km/h versus 209 km/h. At 1,000 metres, the RS e-tron GT finishes in 20.60 s versus 22.50 s, with a 1.90 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 e-tron GT and the X5 M50i 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 6.38 seconds. The 1.01 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, RS e-tron GT wins (3,33 s vs 4,34 s).
