Off the line, the 225i xDrive Active Tourer hits 100 km/h in 6.63 s versus 6.97 s for the 320d Steptronic. Despite the faster sprint time, the 320d Steptronic is 3 m further along the track at this moment: stronger low-speed acceleration offsets a slower run beyond 100 km/h.
At 200 metres, the 225i xDrive Active Tourer is doing 126 km/h against 120 km/h for the 320d Steptronic. The gap is 0.03 s. The challenger starts to claw back ground.
At 400 metres standing start, the 225i xDrive Active Tourer crosses the line in 14.83 s versus 15.10 s. The 0.27 s gap represents roughly 11 m of track - two to three car lengths.
Past 400 metres, the 225i xDrive Active Tourer continues to build its lead. At 600 metres, it runs at 174 km/h versus 167 km/h. At 1,000 metres, the 225i xDrive Active Tourer finishes in 26.93 s versus 27.70 s, with a 0.77 s lead. Both vehicles have similar top speeds (234 vs 237 km/h), preventing any comeback.
Both rivals are electronically governed, but not at the same level: the 225i xDrive Active Tourer is capped at 235 km/h, the 320d Steptronic 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 7.66 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 11.35 seconds. The 0.34 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, 225i xDrive Active Tourer F44 wins (6,63 s vs 6,97 s).
225i xDrive Active Tourer F44 goes from 0 to 100 km/h in 6,63 seconds (calibrated simulation).
