Off the line, the Bmw M140i hits 100 km/h in 4.54 s versus 6.22 s for the Bmw 128ti. At this point, the Bmw M140i leads by 1.68 s and sits roughly 18 m ahead.
At 200 metres, the Bmw M140i is doing 151 km/h against 136 km/h for the Bmw 128ti. The gap is 1.26 s. The challenger starts to claw back ground.
At 400 metres standing start, the Bmw M140i crosses the line in 12.60 s versus 14.31 s. The 1.71 s gap represents roughly 78 m of track — a gap visible to the naked eye.
Past 400 metres, the Bmw M140i continues to build its lead. At 600 metres, it runs at 210 km/h versus 190 km/h. At 1,000 metres, the Bmw M140i finishes in 22.65 s versus 25.37 s, with a 2.73 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 128ti 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 5.45 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 8.97 seconds. The 1.68 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.
