Off the line, the A5 Sedan hits 100 km/h in 7.79 s versus 9.90 s for the A3 Sportback. At this point, the A5 Sedan leads by 2.11 s and sits roughly 19 m ahead.
At 200 metres, the A5 Sedan is doing 117 km/h against 108 km/h for the A3 Sportback. The gap is 1.00 s. The challenger starts to claw back ground.
At 400 metres standing start, the A5 Sedan crosses the line in 15.74 s versus 17.23 s. The 1.49 s gap represents roughly 54 m of track - a gap visible to the naked eye.
Past 400 metres, the A5 Sedan continues to build its lead. At 600 metres, it runs at 162 km/h versus 149 km/h. At 1,000 metres, the A5 Sedan finishes in 28.62 s versus 31.33 s, with a 2.71 s lead.
Electronically capped at 242 km/h, the A5 Sedan 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 (8.92 kg/hp vs 11.68 kg/hp) and transmission (Automatic vs Manual).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 16.37 seconds. The 2.11 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, A5 Sedan wins (7,79 s vs 9,90 s).
A5 Sedan goes from 0 to 100 km/h in 7,79 seconds (calibrated simulation).
