The XC90 may still feel fresh, but it actually pioneered the current design language seen on all new Volvos, and it's been kicking around since 2015, so it was time to add a bit of freshness.
The exterior is just a little different, with Volvo throwing in some new wheel designs and paint colors, in addition to a new grille and other subtle adjustments.
Perhaps the most notable upgrade for 2020 is the addition of a new mild hybrid trim, which will carry a new B badge, living alongside the T6 and T8 variants from before.
