Off the line, the M240i Convertible hits 100 km/h in 4.66 s versus 8.68 s for the 218d Gran Coupe. At this point, the M240i Convertible leads by 4.02 s and sits roughly 23 m ahead.
At 200 metres, the M240i Convertible is doing 145 km/h against 112 km/h for the 218d Gran Coupe. The gap is 2.24 s. The challenger starts to claw back ground.
At 400 metres standing start, the M240i Convertible crosses the line in 12.85 s versus 16.40 s. The 3.55 s gap represents roughly 129 m of track - a gap visible to the naked eye.
Past 400 metres, the M240i Convertible continues to build its lead. At 600 metres, it runs at 201 km/h versus 155 km/h. At 1,000 metres, the M240i Convertible finishes in 23.31 s versus 29.93 s, with a 6.62 s lead.
Both rivals are electronically governed, but not at the same level: the M240i 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 (4.88 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 4.02 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, M240i Convertible F44 wins (4,66 s vs 8,68 s).
M240i Convertible F44 goes from 0 to 100 km/h in 4,66 seconds (calibrated simulation).
M240i Convertible F44: 340 hp, ratio 4,88 kg/hp. 218d Gran Coupe F44: 150 hp, ratio 9,50 kg/hp.
M240i Convertible F44: 250 km/h. 218d Gran Coupe F44: 222 km/h.
