Off the line, the 840d xDrive Convertible hits 100 km/h in 5.06 s versus 8.68 s for the 218d Gran Coupe. At this point, the 840d xDrive Convertible leads by 3.62 s and sits roughly 25 m ahead.
At 200 metres, the 840d xDrive Convertible is doing 137 km/h against 112 km/h for the 218d Gran Coupe. The gap is 1.97 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 16.40 s. The 3.04 s gap represents roughly 111 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 155 km/h. At 1,000 metres, the 840d xDrive Convertible finishes in 24.31 s versus 29.93 s, with a 5.62 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 Gran Coupe at 222 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 9.50 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 14.34 seconds. The 3.62 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 8,68 s).
840d xDrive Convertible G15 goes from 0 to 100 km/h in 5,06 seconds (calibrated simulation).
