Off the line, the A3 Sportback hits 100 km/h in 9.90 s versus 9.98 s for the A5 Sedan. The 0.08 s gap is negligible: both vehicles are neck and neck.
At 200 metres, the A3 Sportback is doing 108 km/h against 108 km/h for the A5 Sedan. The gap is 0.09 s. The gap remains stable from the start.
At 400 metres standing start, the A3 Sportback crosses the line in 17.23 s versus 17.30 s. The 0.07 s gap represents roughly 3 m of track - barely a car length.
Past 400 metres, the situation changes. The A3 Sportback maxes out at 209 km/h while the A5 Sedan keeps accelerating towards 216 km/h. At 600 metres, the gap has dropped to 0.04 s.
Around 769 metres, both vehicles are level. This is the inversion point: the A5 Sedan overcomes its launch deficit thanks to a 7 km/h higher top speed.
At 1,000 metres, the A5 Sedan finishes in 31.28 s versus 31.33 s. The 0.06 s delta shows an extremely tight race.
Electronically capped at 216 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 (11.30 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 0.08 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
