Off the line, the S90 B5 AWD hits 100 km/h in 6.58 s versus 7.56 s for the Bmw 520i. At this point, the S90 B5 AWD leads by 0.98 s and sits roughly 10 m ahead.
At 200 metres, the S90 B5 AWD is doing 125 km/h against 119 km/h for the Bmw 520i. The gap is 0.56 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 15.58 s. The 0.83 s gap represents roughly 34 m of track - a gap visible to the naked eye.
Past 400 metres, the S90 B5 AWD continues to build its lead. At 600 metres, it runs at 176 km/h versus 166 km/h. At 1,000 metres, the S90 B5 AWD finishes in 27.11 s versus 28.25 s, with a 1.15 s lead. Despite a higher top speed (230 km/h), the Bmw 520i never recovers its launch deficit.
The S90 B5 AWD features all-wheel drive (AWD) against the Bmw 520i’s RWD. At low speeds (0-30, 0-50, 0-80 km/h), AWD doubles the driven contact area: all four wheels transmit torque to the road, virtually eliminating wheelspin at launch. This traction advantage is decisive in the range where the motor delivers peak torque, before power and aerodynamics take over.
Both rivals are electronically governed, but not at the same level: the S90 B5 AWD is capped at 180 km/h, the Bmw 520i at 230 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 8.29 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 12.02 seconds. The 0.98 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
