Off the line, the M240i hits 100 km/h in 4.67 s versus 4.78 s for the M135i xDrive. The 0.12 s gap is negligible: both vehicles are neck and neck.
At 200 metres, the M240i is doing 147 km/h against 144 km/h for the M135i xDrive. The gap is 0.11 s. The gap remains stable from the start.
At 400 metres standing start, the M240i crosses the line in 12.78 s versus 13.00 s. The 0.22 s gap represents roughly 11 m of track - two to three car lengths.
Past 400 metres, the M240i continues to build its lead. At 600 metres, it runs at 205 km/h versus 199 km/h. At 1,000 metres, the M240i finishes in 23.03 s versus 23.59 s, with a 0.56 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 M240i and the M135i xDrive 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 (4.49 kg/hp vs 4.98 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 7.19 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.
