From what I can see, the battery in the XC90 has increased from 11.6Kwh to 18.8Kwh. That's a 62% increase.

If we make an assumption that there's no snake oil improvements achievable, then an XC90 should see a 62% increase in range.

Given most XC90 T8 owners see around 20-25 miles, then the new real world range I'd expect to be in the region of 32-40 miles, all things being equal, but prepare for it being more towards the 32 end unless you drive in a manner to maximise range.

Of course, 18.8Kwh of battery brings extra weight to the equation, but think in broad terms, 32-40 miles would be a realistic expectation?? Volvo may have made some efficiency improvements which might increase it (or perhaps decrease it!).
