Off the line, the Bmw 120i hits 100 km/h in 7.12 s versus 7.38 s for the Bmw 120d. At this point, the Bmw 120i leads by 0.26 s and sits roughly 2 m ahead.
At 200 metres, the Bmw 120i is doing 122 km/h against 121 km/h for the Bmw 120d. The gap is 0.14 s. The challenger starts to claw back ground.
At 400 metres standing start, the Bmw 120i crosses the line in 15.22 s versus 15.41 s. The 0.19 s gap represents roughly 8 m of track — barely a car length.
Past 400 metres, the Bmw 120i continues to build its lead. At 600 metres, it runs at 170 km/h versus 168 km/h. At 1,000 metres, the Bmw 120i finishes in 27.52 s versus 27.90 s, with a 0.37 s lead. Both vehicles have similar top speeds (231 vs 225 km/h), preventing any comeback.
Both rivals are electronically governed, but not at the same level: the Bmw 120d is capped at 231 km/h, the Bmw 120i at 225 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 7.47 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 11.54 seconds. The 0.26 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.
