Off the line, the Bmw 420d hits 100 km/h in 7.04 s versus 7.38 s for the Bmw 120d. At this point, the Bmw 420d leads by 0.34 s and sits roughly 12 m ahead.
At 200 metres, the Bmw 420d is doing 119 km/h against 121 km/h for the Bmw 120d. The gap is 0.41 s. The gap remains stable from the start.
At 400 metres standing start, the Bmw 420d crosses the line in 15.10 s versus 15.41 s. The 0.31 s gap represents roughly 13 m of track — two to three car lengths.
Past 400 metres, the gap narrows. The Bmw 120d maxes out at 231 km/h while the Bmw 420d keeps accelerating towards 240 km/h. At 600 metres, the gap has dropped to 0.23 s.
At 1,000 metres, the Bmw 420d finishes in 27.77 s versus 27.90 s, with just 0.12 s to spare. The Bmw 120d fails to fully close the launch gap.
Both rivals are electronically governed, but not at the same level: the Bmw 120d is capped at 231 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 (7.63 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 0.34 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.
