Off the line, the S90 B5 AWD hits 100 km/h in 6.58 s versus 7.47 s for the 520d Touring. Despite the faster sprint time, the 520d Touring is 1 m further along the track at this moment: stronger low-speed acceleration offsets a slower run beyond 100 km/h.
At 200 metres, the S90 B5 AWD is doing 125 km/h against 115 km/h for the 520d Touring. The gap is 0.21 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 15.42 s. The 0.67 s gap represents roughly 26 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 160 km/h. At 1,000 metres, the S90 B5 AWD finishes in 27.11 s versus 28.59 s, with a 1.49 s lead. Despite a higher top speed (225 km/h), the 520d Touring 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 520d Touring at 225 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 9.16 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 12.58 seconds. The 0.89 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
