Volvo S90 B5 AWD vs BMW 225xe iPerformance F44: which is truly faster?

Off the line, the S90 B5 AWD hits 100 km/h in 6.58 s versus 6.80 s for the 225xe iPerformance. Despite lacking instant torque, 250 hp of power compensates. At this point, the S90 B5 AWD leads by 0.22 s and sits roughly 7 m ahead.

At 200 metres, the S90 B5 AWD is doing 125 km/h against 126 km/h for the 225xe iPerformance. The gap is 0.24 s. The gap remains stable from the start.

At 400 metres standing start, the S90 B5 AWD crosses the line in 14.75 s versus 14.96 s. The 0.20 s gap represents roughly 9 m of track - barely a car length.

Past 400 metres, the situation changes. The S90 B5 AWD maxes out at 180 km/h while the 225xe iPerformance keeps accelerating towards 202 km/h. At 600 metres, the gap has dropped to 0.18 s.

Around 893 metres, both vehicles are level. This is the inversion point: the 225xe iPerformance overcomes its launch deficit thanks to a 22 km/h higher top speed.

At 1,000 metres, the 225xe iPerformance finishes in 26.93 s versus 27.11 s. The 0.18 s delta shows an extremely tight race.

Both rivals are electronically governed, but not at the same level: the S90 B5 AWD is capped at 180 km/h, the 225xe iPerformance at 202 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.

Instant electric torque gives an advantage off the line. The higher top speed of the combustion engine gives an advantage over longer distances. The distance at which one catches the other depends on the top speed differential.

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 10.41 seconds. The 0.22 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
