yeah its like 800+liters or something , plus the under floor storage and about 120l in the frunk
For some reason Tesla is incredibly coy on giving specific measurements on boot space - the large figure that is normally bandied about is filling the boot to the roof level, as opposed to the more normal window level (until recently, the Y didn't come with a cargo cover; I'm guessing that's their excuse for doing this). But, yeah, as shown in the photos I've included above, even the main boot compartment is about the largest of the 'affordable' EVs (along with the Skoda Enyaq), and when adding the under-floor space and the frunk it's fantastically well-off for storage.
Weirdly, few of the other options have a meaningful frunk if anything. I'm really looking forward to having one - even if it's just for the benefit of no more remaining curry or pizza smells!
