Surely that can’t be right? Isn’t space saver just tyre WIDTH!?

That seems about right, I have an 18" rim with 125x80 tyre. But the well is a lot wider than the wheel and with a little juggling can see why a full size wont fit if you are OK with the lid not being flat.
I have 18” wheels with 235/55R18 tires. My factory fitted space saver is 18” with 125/80R18 tire. So it’s correct what you see in the picture.
If you order the car with larger rims then the space saver size will differ, See JFDIT measurements, he has 20” wheels on his car.
The space saver is inflated to a higher PSI and doesn't deform when fitted whereas the normal wheel does get a flat bottom, wouldn't this make the sizes slightly more equal?

They don't need to be equal, just the car can cope with the difference sizes. Hence the speed and distance limitations
Do the sums.
Rim size is in inches.
Tyre width is in millimeters.
The first number is the tyre width in my case 245mm
The second number, 45 for mine, is the tyre wall depth as a percentage of the tyre width so that's 110.25mm x 2 = 220.5mm = 8.7 inches. Add to 20 Inch rim and you get a total wheel diameter of 28.7 inches.
Using the same calculation my space saver is 18" rim plus 6.9" for tyre walls = Space Saver wheel size of 24.9 inches.
It's also worth noting that some of those replying may have the older non MHEV which doesn't have the 48v battery in the boot which limits space.

hi ChrisLF , thanks for the welcome, I did answer this but it didn’t appear. I did notice a few days ago that the list price was over£40k but silly me assumed they had been reducedChrisLF wrote: ↑Wed Dec 20, 2023 5:31 pm Hi and welcome.
Yes, it can get its knickers in a twist sometimes. I had to brake quite hard the other day due to cars parked on both sides of the road, nearly came to a halt but then applied power. Nothing much happened but then suddenly lurched forward! Was wondering what the heck was going on and not very refined. Otherwise it's very smooth and the "box" works well.
I'd check about the being under £40k. As I fell foul of this. The price is under the threshold because of the discounts Volvo are applying but the VED is based on the full retail less the first year's VED.
As regards the spare there is some space between the space saver and topmost boot floor but I don't know if there is room for a full-size which is a big wheel. Also the 48v battery is under the boot floor proper.
So yes I am over that so I will change my order with dealer and tell him that configurations are less than list price Thanks Chris
