The start: 0 to 100 km/h

Off the line, the 840d xDrive Convertible hits 100 km/h in 5.06 s versus 7.66 s for the 220d Convertible. At this point, the 840d xDrive Convertible leads by 2.60 s and sits roughly 27 m ahead.

From 100 km/h to 400 metres

At 200 metres, the 840d xDrive Convertible is doing 136 km/h against 120 km/h for the 220d Convertible. The gap is 1.71 s. The challenger starts to claw back ground.

At 400 metres standing start, the 840d xDrive Convertible crosses the line in 13.36 s versus 15.71 s. The 2.35 s gap represents roughly 93 m of track - a gap visible to the naked eye.

Beyond 400 metres: top speed comes into play

Past 400 metres, the 840d xDrive Convertible continues to build its lead. At 600 metres, it runs at 190 km/h versus 167 km/h. At 1,000 metres, the 840d xDrive Convertible finishes in 24.38 s versus 28.34 s, with a 3.96 s lead.

What the numbers don’t tell you

Both rivals are electronically governed, but not at the same level: the 840d xDrive Convertible is capped at 250 (i.e. 155 mph - industry threshold) km/h, the 220d Convertible at 225 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 (5.97 kg/hp vs 8.34 kg/hp) and transmission (Automatic vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 12.00 seconds. The 2.60 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
