Off the line, the RS 5 Sedan hits 100 km/h in 3.73 s versus 7.00 s for the A6 Avant. The instant torque of 825 Nm from the electric motor makes the difference. At this point, the RS 5 Sedan leads by 3.27 s and sits roughly 12 m ahead.
At 200 metres, the RS 5 Sedan is doing 156 km/h against 117 km/h for the A6 Avant. The gap is 1.87 s. The challenger starts to claw back ground.
At 400 metres standing start, the RS 5 Sedan crosses the line in 11.77 s versus 15.02 s. The 3.25 s gap represents roughly 124 m of track - a gap visible to the naked eye.
Past 400 metres, the RS 5 Sedan continues to build its lead. At 600 metres, it runs at 218 km/h versus 161 km/h. At 1,000 metres, the RS 5 Sedan finishes in 21.38 s versus 27.98 s, with a 6.60 s lead. Both vehicles have similar top speeds (250 (i.e. 155 mph - industry threshold) vs 238 km/h), preventing any comeback.
Both rivals are electronically governed, but not at the same level: the RS 5 Sedan is capped at 250 (i.e. 155 mph - industry threshold) km/h, the A6 Avant at 238 km/h. This isn’t a physical engine limit - it’s a manufacturer choice, usually for tyre safety or homologation reasons. Neither car reaches its true aerodynamic top speed.
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 11.76 seconds. The 3.27 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 7,00 s).
