We can see that external changes will be subtle, given the development team hasn’t really bothered to disguise these prototypes. If you look closely you can see tape obscuring the lower grille and bumper details, suggesting small cosmetic tweaks, but otherwise it appears that the S90 and V90’s design won’t be altered greatly.
There will be more significant revisions under the skin, however. Chief among which will be the adoption of 48-volt mild-hybrid technology, already found in the refreshed XC90 and XC60, across most of the lineup.
The system combines a 48-volt battery with an integrated starter-generator and energy recovery system, capturing kinetic energy during braking or coasting and using it to boost overall efficiency. It’s expected that, instead of the ’T’ and ‘D’ badges to signify petrol and diesel variants, both fuel types will be badged ‘B’, with B4, B5 and B6 variants found in the XC60.
