Off the line, the RS 5 Avant hits 100 km/h in 3.66 s versus 7.79 s for the A5 Sedan. The instant torque of 825 Nm from the electric motor makes the difference. At this point, the RS 5 Avant leads by 4.14 s and sits roughly 25 m ahead.
At 200 metres, the RS 5 Avant is doing 156 km/h against 117 km/h for the A5 Sedan. The gap is 2.65 s. The challenger starts to claw back ground.
At 400 metres standing start, the RS 5 Avant crosses the line in 11.72 s versus 15.74 s. The 4.02 s gap represents roughly 152 m of track - a gap visible to the naked eye.
Past 400 metres, the RS 5 Avant continues to build its lead. At 600 metres, it runs at 218 km/h versus 162 km/h. At 1,000 metres, the RS 5 Avant finishes in 21.35 s versus 28.62 s, with a 7.27 s lead. Both vehicles have similar top speeds (250 (i.e. 155 mph - industry threshold) vs 242 km/h), preventing any comeback.
The RS 5 Avant features all-wheel drive (AWD) against the A5 Sedan’s FWD. At low speeds (0-30, 0-50, 0-80 km/h), AWD doubles the driven contact area: all four wheels transmit torque to the road, virtually eliminating wheelspin at launch. This traction advantage is decisive in the range where the motor delivers peak torque, before power and aerodynamics take over.
Both rivals are electronically governed, but not at the same level: the RS 5 Avant is capped at 250 (i.e. 155 mph - industry threshold) km/h, the A5 Sedan at 242 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 12.41 seconds. The 4.14 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, RS 5 Avant wins (3,66 s vs 7,79 s).
RS 5 Avant goes from 0 to 100 km/h in 3,66 seconds (calibrated simulation).
