The start: 0 to 100 km/h

Off the line, the 320d Touring hits 100 km/h in 7.55 s versus 9.82 s for the A3 Sedan. At this point, the 320d Touring leads by 2.27 s and sits roughly 17 m ahead.

From 100 km/h to 400 metres

At 200 metres, the 320d Touring is doing 121 km/h against 108 km/h for the A3 Sedan. The gap is 0.99 s. The challenger starts to claw back ground.

At 400 metres standing start, the 320d Touring crosses the line in 15.61 s versus 17.21 s. The 1.60 s gap represents roughly 58 m of track - a gap visible to the naked eye.

Beyond 400 metres: top speed comes into play

Past 400 metres, the 320d Touring continues to build its lead. At 600 metres, it runs at 167 km/h versus 151 km/h. At 1,000 metres, the 320d Touring finishes in 28.17 s versus 31.15 s, with a 2.97 s lead. Both vehicles have similar top speeds (229 vs 215 km/h), preventing any comeback.

What the numbers don’t tell you

Electronically capped at 229 km/h, the 320d 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 (8.24 kg/hp vs 11.34 kg/hp) and transmission (Automatic vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 16.05 seconds. The 2.27 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
