Off the line, the RS 3 Sportback hits 100 km/h in 3.88 s versus 5.15 s for the X5 M50d. At this point, the RS 3 Sportback leads by 1.28 s and sits roughly 11 m ahead.
At 200 metres, the RS 3 Sportback is doing 150 km/h against 136 km/h for the X5 M50d. The gap is 0.93 s. The challenger starts to claw back ground.
At 400 metres standing start, the RS 3 Sportback crosses the line in 12.08 s versus 13.47 s. The 1.39 s gap represents roughly 64 m of track - a gap visible to the naked eye.
Past 400 metres, the RS 3 Sportback continues to build its lead. At 600 metres, it runs at 211 km/h versus 189 km/h. At 1,000 metres, the RS 3 Sportback finishes in 22.04 s versus 24.60 s, with a 2.56 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 3 Sportback 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 (3.91 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 1.28 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, RS 3 Sportback wins (3,88 s vs 5,15 s).
RS 3 Sportback goes from 0 to 100 km/h in 3,88 seconds (calibrated simulation).
