Off the line, the Bmw 125d hits 100 km/h in 6.48 s versus 6.56 s for the Cooper S FWD. The 0.08 s gap is negligible: both vehicles are neck and neck.
At 200 metres, the Bmw 125d is doing 130 km/h against 132 km/h for the Cooper S FWD. The gap is 0.05 s. The gap remains stable from the start.
At 400 metres standing start, the Cooper S FWD crosses the line in 14.62 s versus 14.67 s. The 0.05 s gap represents roughly 2 m of track - barely a car length.
Past 400 metres, the Cooper S FWD continues to build its lead. At 600 metres, it runs at 184 km/h versus 180 km/h. At 1,000 metres, the Cooper S FWD finishes in 26.02 s versus 26.39 s, with a 0.37 s lead. Both vehicles have similar top speeds (240 vs 250 (i.e. 155 mph - industry threshold) km/h), preventing any comeback.
Electronically capped at 240 km/h, the Bmw 125d never reaches its natural aerodynamic ceiling in this duel. That’s not a physical limit of the motor - it’s a deliberate manufacturer decision, typically tied to standard-fit tyre ratings or model-range positioning.
With two combustion powertrains, the difference comes down to power-to-weight ratio (6.61 kg/hp vs 5.86 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 9.81 seconds. The 0.08 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, 125d F20LCI and Cooper S FWD are neck and neck (6,48 s vs 6,56 s, no significant gap).
125d F20LCI goes from 0 to 100 km/h in 6,48 seconds (calibrated simulation).
