Off the line, the S90 B5 AWD hits 100 km/h in 6.58 s versus 6.97 s for the 320d Steptronic. The 0.39 s gap is negligible: both vehicles are neck and neck.
At 200 metres, the S90 B5 AWD is doing 125 km/h against 120 km/h for the 320d Steptronic. The gap is 0.12 s. The challenger starts to claw back ground.
At 400 metres standing start, the S90 B5 AWD crosses the line in 14.75 s versus 15.10 s. The 0.35 s gap represents roughly 14 m of track - two to three car lengths.
Past 400 metres, the S90 B5 AWD continues to build its lead. At 600 metres, it runs at 176 km/h versus 167 km/h. At 1,000 metres, the S90 B5 AWD finishes in 27.11 s versus 27.70 s, with a 0.59 s lead. Despite a higher top speed (237 km/h), the 320d Steptronic never recovers its launch deficit.
Both rivals are electronically governed, but not at the same level: the S90 B5 AWD is capped at 180 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 (7.18 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 0.39 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
