Off the line, the 120i hits 100 km/h in 6.91 s versus 7.15 s for the 120d. At this point, the 120i leads by 0.24 s and sits roughly 7 m ahead.
At 200 metres, the 120i is doing 124 km/h against 124 km/h for the 120d. The gap is 0.27 s. The gap remains stable from the start.
At 400 metres standing start, the 120i crosses the line in 15.02 s versus 15.30 s. The 0.28 s gap represents roughly 12 m of track - two to three car lengths.
Past 400 metres, the 120i continues to build its lead. At 600 metres, it runs at 174 km/h versus 172 km/h. At 1,000 metres, the 120i finishes in 27.09 s versus 27.53 s, with a 0.44 s lead. Both vehicles have similar top speeds (228 vs 235 km/h), preventing any comeback.
Both rivals are electronically governed, but not at the same level: the 120d is capped at 228 km/h, the 120i at 235 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 (7.45 kg/hp vs 7.81 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 10.99 seconds. The 0.24 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
