The S90 is a midsize luxury sedan that is both pleasant to drive and very comfortable thanks to the Swedish brand's acclaimed seats. The B6 mild hybrid model produces 295 hp and achieves a combined 9.2 L/100 km. With its powerful and efficient plug-in hybrid system, the T8 model produces 455 hp and can travel 61 km in full electric mode. Unfortunately, the S90’s reputation has taken a hit due to subpar reliability, which also affects its resale value.
