Off the line, the Bmw M140i hits 100 km/h in 4.54 s versus 7.04 s for the Bmw 420d. At this point, the Bmw M140i leads by 2.50 s and sits roughly 9 m ahead.
At 200 metres, the Bmw M140i is doing 151 km/h against 119 km/h for the Bmw 420d. The gap is 1.37 s. The challenger starts to claw back ground.
At 400 metres standing start, the Bmw M140i crosses the line in 12.60 s versus 15.10 s. The 2.50 s gap represents roughly 98 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 166 km/h. At 1,000 metres, the Bmw M140i finishes in 22.65 s versus 27.77 s, with a 5.13 s lead. Both vehicles have similar top speeds (250 (i.e. 155 mph - industry threshold) vs 240 km/h), preventing any comeback.
Both rivals are electronically governed, but not at the same level: the Bmw M140i is capped at 250 (i.e. 155 mph - industry threshold) km/h, the Bmw 420d at 240 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 (4.32 kg/hp vs 8.45 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 11.60 seconds. The 2.50 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.
