The start: 0 to 100 km/h

Off the line, the 225d Convertible hits 100 km/h in 6.54 s versus 8.22 s for the A3 Sedan. At this point, the 225d Convertible leads by 1.68 s and sits roughly 21 m ahead.

From 100 km/h to 400 metres

At 200 metres, the 225d Convertible is doing 127 km/h against 119 km/h for the A3 Sedan. The gap is 1.05 s. The challenger starts to claw back ground.

At 400 metres standing start, the 225d Convertible crosses the line in 14.76 s versus 16.09 s. The 1.33 s gap represents roughly 54 m of track - a gap visible to the naked eye.

Beyond 400 metres: top speed comes into play

Past 400 metres, the 225d Convertible continues to build its lead. At 600 metres, it runs at 175 km/h versus 168 km/h. At 1,000 metres, the 225d Convertible finishes in 26.79 s versus 28.62 s, with a 1.82 s lead. Both vehicles have similar top speeds (231 vs 240 km/h), preventing any comeback.

What the numbers don’t tell you

Electronically capped at 231 km/h, the 225d Convertible 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 (7.25 kg/hp vs 8.60 kg/hp) and transmission (Automatic vs Manual).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 12.45 seconds. The 1.68 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
