Off the line, the A5 Sedan hits 100 km/h in 7.79 s versus 8.38 s for the A3 allstreet. At this point, the A5 Sedan leads by 0.59 s and sits roughly 4 m ahead.
At 200 metres, the A5 Sedan is doing 117 km/h against 114 km/h for the A3 allstreet. The gap is 0.23 s. The challenger starts to claw back ground.
At 400 metres standing start, the A5 Sedan crosses the line in 15.74 s versus 16.10 s. The 0.37 s gap represents roughly 14 m of track - two to three car lengths.
Past 400 metres, the A5 Sedan continues to build its lead. At 600 metres, it runs at 162 km/h versus 159 km/h. At 1,000 metres, the A5 Sedan finishes in 28.62 s versus 29.31 s, with a 0.69 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 9.57 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 13.44 seconds. The 0.59 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 8,38 s).
A5 Sedan goes from 0 to 100 km/h in 7,79 seconds (calibrated simulation).
