Off the line, the RS 5 Sedan hits 100 km/h in 3.73 s versus 3.88 s for the RS 3 Sportback. The instant torque of 825 Nm from the electric motor makes the difference. At this point, the RS 5 Sedan leads by 0.15 s and sits roughly 2 m ahead.
At 200 metres, the RS 5 Sedan is doing 156 km/h against 150 km/h for the RS 3 Sportback. The gap is 0.15 s. The gap remains stable from the start.
At 400 metres standing start, the RS 5 Sedan crosses the line in 11.77 s versus 12.08 s. The 0.31 s gap represents roughly 16 m of track - two to three car lengths.
Past 400 metres, the RS 5 Sedan continues to build its lead. At 600 metres, it runs at 218 km/h versus 211 km/h. At 1,000 metres, the RS 5 Sedan finishes in 21.38 s versus 22.04 s, with a 0.67 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 Sedan and the RS 3 Sportback 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 5.79 seconds. The 0.15 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, RS 5 Sedan wins (3,73 s vs 3,88 s).
