Off the line, the 840d xDrive Convertible hits 100 km/h in 5.06 s versus 8.35 s for the 218d. At this point, the 840d xDrive Convertible leads by 3.29 s and sits roughly 24 m ahead.
At 200 metres, the 840d xDrive Convertible is doing 137 km/h against 114 km/h for the 218d. The gap is 1.87 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 16.17 s. The 2.81 s gap represents roughly 106 m of track - a gap visible to the naked eye.
Past 400 metres, the 840d xDrive Convertible continues to build its lead. At 600 metres, it runs at 192 km/h versus 158 km/h. At 1,000 metres, the 840d xDrive Convertible finishes in 24.31 s versus 29.45 s, with a 5.14 s lead.
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 218d at 213 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 9.47 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 13.58 seconds. The 3.29 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, 840d xDrive Convertible G15 wins (5,06 s vs 8,35 s).
840d xDrive Convertible G15 goes from 0 to 100 km/h in 5,06 seconds (calibrated simulation).
