The start: 0 to 100 km/h

Off the line, the 218i Convertible hits 100 km/h in 9.34 s versus 9.87 s for the A3 Sedan. At this point, the 218i Convertible leads by 0.53 s and sits roughly 7 m ahead.

From 100 km/h to 400 metres

At 200 metres, the 218i Convertible is doing 110 km/h against 108 km/h for the A3 Sedan. The gap is 0.30 s. The challenger starts to claw back ground.

At 400 metres standing start, the 218i Convertible crosses the line in 16.78 s versus 17.21 s. The 0.42 s gap represents roughly 16 m of track - two to three car lengths.

Beyond 400 metres: top speed comes into play

Past 400 metres, the 218i Convertible continues to build its lead. At 600 metres, it runs at 154 km/h versus 150 km/h. At 1,000 metres, the 218i Convertible finishes in 30.47 s versus 31.24 s, with a 0.77 s lead. Both vehicles have similar top speeds (207 vs 215 km/h), preventing any comeback.

What the numbers don’t tell you

Electronically capped at 207 km/h, the 218i 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 (11.47 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 16.25 seconds. The 0.53 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
