Off the line, the RS 5 Sedan hits 100 km/h in 3.73 s versus 4.08 s for the S6 Sportback e-tron. At this point, the RS 5 Sedan leads by 0.35 s and sits roughly 5 m ahead.
At 200 metres, the RS 5 Sedan is doing 156 km/h against 146 km/h for the S6 Sportback e-tron. The gap is 0.37 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 12.52 s. The 0.75 s gap represents roughly 36 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 191 km/h. At 1,000 metres, the RS 5 Sedan finishes in 21.38 s versus 23.58 s, with a 2.20 s lead.
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 S6 Sportback e-tron at 240 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.
With two plug-in hybrid powertrains, the difference comes down to power-to-weight ratio (3.69 kg/hp vs 4.28 kg/hp) and transmission (Automatic vs Unknown).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 6.31 seconds. The 0.35 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 4,08 s).
RS 5 Sedan goes from 0 to 100 km/h in 3,73 seconds (calibrated simulation).
