Off the line, the Bmw 125d hits 100 km/h in 6.48 s versus 6.63 s for the Bmw 225i xDrive Active Tourer. Despite the faster sprint time, the Bmw 225i xDrive Active Tourer is 2 m further along the track at this moment: stronger low-speed acceleration offsets a slower run beyond 100 km/h.
At 200 metres, the Bmw 125d is doing 130 km/h against 126 km/h for the Bmw 225i xDrive Active Tourer. The gap is 0.01 s. The challenger starts to claw back ground.
At 400 metres standing start, the Bmw 125d crosses the line in 14.67 s versus 14.83 s. The 0.15 s gap represents roughly 7 m of track - barely a car length.
Past 400 metres, the Bmw 125d continues to build its lead. At 600 metres, it runs at 180 km/h versus 174 km/h. At 1,000 metres, the Bmw 125d finishes in 26.39 s versus 26.93 s, with a 0.53 s lead. Both vehicles have similar top speeds (234 vs 240 km/h), preventing any comeback.
Both rivals are electronically governed, but not at the same level: the Bmw 225i xDrive Active Tourer is capped at 235 km/h, the Bmw 125d at 240 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 (6.58 kg/hp vs 6.61 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 0.15 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, 125d F20LCI wins (6,48 s vs 6,63 s).
225i xDrive Active Tourer F44 goes from 0 to 100 km/h in 6,63 seconds (calibrated simulation).
