Off the line, the 225d Convertible hits 100 km/h in 6.54 s versus 8.92 s for the 218d xDrive. At this point, the 225d Convertible leads by 2.38 s and sits roughly 22 m ahead.
At 200 metres, the 225d Convertible is doing 127 km/h against 113 km/h for the 218d xDrive. The gap is 1.31 s. The challenger starts to claw back ground.
At 400 metres standing start, the 225d Convertible crosses the line in 14.76 s versus 16.67 s. The 1.91 s gap represents roughly 72 m of track - a gap visible to the naked eye.
Past 400 metres, the 225d Convertible continues to build its lead. At 600 metres, it runs at 175 km/h versus 157 km/h. At 1,000 metres, the 225d Convertible finishes in 26.79 s versus 30.09 s, with a 3.29 s lead.
Both rivals are electronically governed, but not at the same level: the 225d Convertible is capped at 231 km/h, the 218d xDrive at 209 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 (7.25 kg/hp vs 10.13 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 14.27 seconds. The 2.38 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
