Off the line, the S90 B5 AWD hits 100 km/h in 6.58 s versus 7.72 s for the A5 Avant. At this point, the S90 B5 AWD leads by 1.14 s and sits roughly 18 m ahead.
At 200 metres, the S90 B5 AWD is doing 125 km/h against 122 km/h for the A5 Avant. The gap is 0.82 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 15.70 s. The 0.95 s gap represents roughly 39 m of track - a gap visible to the naked eye.
Past 400 metres, the gap narrows. The S90 B5 AWD maxes out at 180 km/h while the A5 Avant keeps accelerating towards 245 km/h. At 600 metres, the gap is down to 1.05 s from 0.95 s at 400 metres.
At 1,000 metres, the S90 B5 AWD finishes in 27.11 s versus 27.94 s, with just 0.83 s to spare. The A5 Avant fails to fully close the launch gap.
The S90 B5 AWD features all-wheel drive (AWD) against the A5 Avant’s FWD. 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 A5 Avant at 245 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 8.38 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 11.72 seconds. The 1.14 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
