Volvo has revealed its latest S90 and V90 models, adding new refinements both inside and out. The exterior on both models now features new fog lights, a new spoiler design, and a new lower front bumper. On the V90 and V90 Cross Country, the rear lights get a new design, full LED lighting, and a sequential turn indicator. The interior adds an upgraded Bowers & Wilkins sound system with an upgraded amplifier, vehicle noise cancellation, dual USB-C charging ports at the rear, and there's also an Advanced Air Cleaner with a PM 2.5 particle sensor that can monitor the cabin's air quality and clean it in a matter of minutes. Both models will also be available with new mild-hybrid engine options that the brand says will see a 15% increase in efficency.
