Off the line, the A4 40 TFSI hits 100 km/h in 7.28 s versus 7.48 s for the 320i Touring. Despite the faster sprint time, the 320i Touring is 2 m further along the track at this moment: stronger low-speed acceleration offsets a slower run beyond 100 km/h.
At 200 metres, the 320i Touring is doing 117 km/h against 119 km/h for the A4 40 TFSI. The gap is 0.03 s. The challenger starts to claw back ground.
At 400 metres standing start, the A4 40 TFSI crosses the line in 15.36 s versus 15.44 s. The 0.08 s gap represents roughly 3 m of track - barely a car length.
Past 400 metres, the A4 40 TFSI continues to build its lead. At 600 metres, it runs at 165 km/h versus 162 km/h. At 1,000 metres, the A4 40 TFSI finishes in 28.08 s versus 28.40 s, with a 0.32 s lead. Both vehicles have similar top speeds (232 vs 230 km/h), preventing any comeback.
Electronically capped at 230 km/h, the 320i Touring 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 (7.97 kg/hp vs 8.53 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 12.30 seconds. The 0.20 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
