Off the line, the 225i xDrive hits 100 km/h in 6.41 s versus 6.58 s for the S90 B5 AWD. The 0.17 s gap is negligible: both vehicles are neck and neck.
At 200 metres, the 225i xDrive is doing 128 km/h against 125 km/h for the S90 B5 AWD. The gap is 0.05 s. The challenger starts to claw back ground.
At 400 metres standing start, the 225i xDrive crosses the line in 14.60 s versus 14.75 s. The 0.15 s gap represents roughly 7 m of track - barely a car length.
Past 400 metres, the 225i xDrive continues to build its lead. At 600 metres, it runs at 177 km/h versus 176 km/h. At 1,000 metres, the 225i xDrive finishes in 26.49 s versus 27.11 s, with a 0.62 s lead.
Both rivals are electronically governed, but not at the same level: the S90 B5 AWD is capped at 180 km/h, the 225i xDrive 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 (7.18 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 10.37 seconds. The 0.17 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
