Off the line, the 840d xDrive Gran Coupe hits 100 km/h in 5.11 s versus 9.34 s for the 218i Convertible. At this point, the 840d xDrive Gran Coupe leads by 4.23 s and sits roughly 27 m ahead.
At 200 metres, the 840d xDrive Gran Coupe is doing 137 km/h against 110 km/h for the 218i Convertible. The gap is 2.24 s. The challenger starts to claw back ground.
At 400 metres standing start, the 840d xDrive Gran Coupe crosses the line in 13.41 s versus 16.78 s. The 3.37 s gap represents roughly 121 m of track - a gap visible to the naked eye.
Past 400 metres, the 840d xDrive Gran Coupe continues to build its lead. At 600 metres, it runs at 191 km/h versus 154 km/h. At 1,000 metres, the 840d xDrive Gran Coupe finishes in 24.41 s versus 30.47 s, with a 6.06 s lead.
Both rivals are electronically governed, but not at the same level: the 840d xDrive Gran Coupe is capped at 250 (i.e. 155 mph - industry threshold) km/h, the 218i Convertible at 207 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 (5.87 kg/hp vs 11.47 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 15.16 seconds. The 4.23 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, 840d xDrive Gran Coupe G15 wins (5,11 s vs 9,34 s).
840d xDrive Gran Coupe G15 goes from 0 to 100 km/h in 5,11 seconds (calibrated simulation).
