Off the line, the S5 Avant hits 100 km/h in 4.53 s versus 8.22 s for the A3 Sedan. At this point, the S5 Avant leads by 3.70 s and sits roughly 33 m ahead.
At 200 metres, the S5 Avant is doing 142 km/h against 119 km/h for the A3 Sedan. The gap is 2.44 s. The challenger starts to claw back ground.
At 400 metres standing start, the S5 Avant crosses the line in 12.83 s versus 16.09 s. The 3.26 s gap represents roughly 128 m of track - a gap visible to the naked eye.
Past 400 metres, the S5 Avant continues to build its lead. At 600 metres, it runs at 197 km/h versus 168 km/h. At 1,000 metres, the S5 Avant finishes in 23.49 s versus 28.62 s, with a 5.13 s lead. Both vehicles have similar top speeds (250 (i.e. 155 mph - industry threshold) vs 240 km/h), preventing any comeback.
The S5 Avant features all-wheel drive (AWD) against the A3 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.
Electronically capped at 250 (i.e. 155 mph - industry threshold) km/h, the S5 Avant never reaches its natural aerodynamic ceiling in this duel. That’s not a physical limit of the motor - it’s a deliberate manufacturer decision, typically tied to standard-fit tyre ratings or model-range positioning.
With two combustion powertrains, the difference comes down to power-to-weight ratio (5.35 kg/hp vs 8.60 kg/hp) and transmission (Automatic vs Manual).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 12.45 seconds. The 3.70 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, S5 Avant wins (4,53 s vs 8,22 s).
S5 Avant goes from 0 to 100 km/h in 4,53 seconds (calibrated simulation).
