Off the line, the M240i Convertible hits 100 km/h in 4.66 s versus 4.83 s for the M440i. At this point, the M240i Convertible leads by 0.17 s and sits roughly 4 m ahead.
At 200 metres, the M240i Convertible is doing 145 km/h against 146 km/h for the M440i. The gap is 0.13 s. The gap remains stable from the start.
At 400 metres standing start, the M240i Convertible crosses the line in 12.85 s versus 12.93 s. The 0.08 s gap represents roughly 4 m of track - barely a car length.
Past 400 metres, the situation changes. Past 400 metres, both rivals hit the same electronic ceiling at 250 (i.e. 155 mph - industry threshold) km/h. Neither can claw back ground through top speed - the outcome hinges on the acceleration curve between 100 and 250 (i.e. 155 mph - industry threshold) km/h.
At 1,000 metres, the M440i finishes in 23.15 s versus 23.31 s. The 0.16 s delta shows an extremely tight race.
Both rivals share the same electronic speed cap: the M440i and the M240i Convertible are governed to 250 (i.e. 155 mph - industry threshold) km/h. At that speed, standard-fit tyres approach their safety threshold - an industrial ceiling common to most electric vehicles in this segment. Neither car shows its true aerodynamic potential in this duel.
With two combustion powertrains, the difference comes down to power-to-weight ratio (4.53 kg/hp vs 4.88 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 7.06 seconds. The 0.17 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 4,83 s).
M440i G22 goes from 0 to 100 km/h in 4,83 seconds (calibrated simulation).
M440i G22: 374 hp, ratio 4,53 kg/hp. M240i Convertible F44: 340 hp, ratio 4,88 kg/hp.
M440i G22: 250 km/h. M240i Convertible F44: 250 km/h.
