Off the line, the Bmw 420i hits 100 km/h in 7.44 s versus 8.41 s for the Bmw 118d. At this point, the Bmw 420i leads by 0.97 s and sits roughly 19 m ahead.
At 200 metres, the Bmw 420i is doing 117 km/h against 115 km/h for the Bmw 118d. The gap is 0.75 s. The challenger starts to claw back ground.
At 400 metres standing start, the Bmw 420i crosses the line in 15.38 s versus 16.25 s. The 0.87 s gap represents roughly 34 m of track - a gap visible to the naked eye.
Past 400 metres, the Bmw 420i continues to build its lead. At 600 metres, it runs at 163 km/h versus 159 km/h. At 1,000 metres, the Bmw 420i finishes in 28.23 s versus 29.46 s, with a 1.23 s lead.
Both rivals are electronically governed, but not at the same level: the Bmw 420i is capped at 240 km/h, the Bmw 118d at 218 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 (8.29 kg/hp vs 9.37 kg/hp) and transmission (Automatic vs Manual).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 13.51 seconds. The 0.97 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.
