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 6.27 s versus 6.63 s for the 225i xDrive Active Tourer. The 0.36 s gap is negligible: both vehicles are neck and neck.
At 200 metres, the 128ti is doing 132 km/h against 126 km/h for the 225i xDrive Active Tourer. The gap is 0.13 s. The challenger starts to claw back ground.
At 400 metres standing start, the 128ti crosses the line in 14.44 s versus 14.83 s. The 0.39 s gap represents roughly 17 m of track - two to three car lengths.
Past 400 metres, the 128ti continues to build its lead. At 600 metres, it runs at 184 km/h versus 174 km/h. At 1,000 metres, the 128ti finishes in 25.86 s versus 26.93 s, with a 1.06 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 225i xDrive Active Tourer 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 6.58 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 10.33 seconds. The 0.36 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, 128ti F40 wins (6,27 s vs 6,63 s).
128ti F40 goes from 0 to 100 km/h in 6,27 seconds (calibrated simulation).
