Physics model calibrated on manufacturer splits. The limited top speed is not the real aerodynamic top speed of the vehicles.
Manufacturer technical specifications. The power-to-weight ratio is the key physical factor in a drag race.

Off the line, the 128ti hits 100 km/h in 6.22 s versus 6.91 s for the 120i. The 0.69 s gap is negligible: both vehicles are neck and neck.
At 200 metres, the 128ti is doing 136 km/h against 124 km/h for the 120i. The gap is 0.26 s. The challenger starts to claw back ground.
At 400 metres standing start, the 128ti crosses the line in 14.31 s versus 15.02 s. The 0.71 s gap represents roughly 30 m of track - a gap visible to the naked eye.
Past 400 metres, the 128ti continues to build its lead. At 600 metres, it runs at 190 km/h versus 174 km/h. At 1,000 metres, the 128ti finishes in 25.37 s versus 27.09 s, with a 1.72 s lead.
Both rivals are electronically governed, but not at the same level: the 128ti is capped at 250 (i.e. 155 mph - industry threshold) 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 (5.45 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 10.76 seconds. The 0.69 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.
