Off the line, the Bmw M140i hits 100 km/h in 4.54 s versus 4.66 s for the Bmw M240i Convertible. Despite the faster sprint time, the Bmw M240i Convertible is 2 m further along the track at this moment: stronger low-speed acceleration offsets a slower run beyond 100 km/h.
At 200 metres, the Bmw M140i is doing 151 km/h against 145 km/h for the Bmw M240i Convertible. The gap is 0.07 s. The gap remains stable from the start.
At 400 metres standing start, the Bmw M140i crosses the line in 12.60 s versus 12.85 s. The 0.25 s gap represents roughly 12 m of track — two to three car lengths.
Past 400 metres, the Bmw M140i continues to build its lead. At 600 metres, it runs at 210 km/h versus 201 km/h. At 1,000 metres, the Bmw M140i finishes in 22.65 s versus 23.31 s, with a 0.67 s lead. Both vehicles have similar top speeds (250 (i.e. 155 mph — industry threshold) vs 250 (i.e. 155 mph — industry threshold) km/h), preventing any comeback.
Both rivals share the same electronic speed cap: the Bmw M140i and the Bmw 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 (4.32 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 6.97 seconds. The 0.12 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Swap one of the two models to explore an equivalent duel in the same segment.
