The start: 0 to 100 km/h

Off the line, the 320d xDrive hits 100 km/h in 6.97 s versus 7.69 s for the 220i Convertible. At this point, the 320d xDrive leads by 0.72 s and sits roughly 6 m ahead.

From 100 km/h to 400 metres

At 200 metres, the 320d xDrive is doing 119 km/h against 115 km/h for the 220i Convertible. The gap is 0.32 s. The challenger starts to claw back ground.

At 400 metres standing start, the 320d xDrive crosses the line in 15.09 s versus 15.61 s. The 0.52 s gap represents roughly 20 m of track - two to three car lengths.

Beyond 400 metres: top speed comes into play

Past 400 metres, the 320d xDrive continues to build its lead. At 600 metres, it runs at 165 km/h versus 160 km/h. At 1,000 metres, the 320d xDrive finishes in 27.84 s versus 28.82 s, with a 0.98 s lead. Both vehicles have similar top speeds (232 vs 220 km/h), preventing any comeback.

What the numbers don’t tell you

Both rivals are electronically governed, but not at the same level: the 320d xDrive is capped at 233 km/h, the 220i Convertible at 226 km/h. This isn’t a physical engine limit - it’s a manufacturer choice, usually for tyre safety or homologation reasons. Neither car reaches its true aerodynamic top speed.

With two combustion powertrains, the difference comes down to power-to-weight ratio (8.11 kg/hp vs 8.37 kg/hp) and transmission (Automatic vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 12.89 seconds. The 0.72 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
