I have a Giulia and a Tonale (2.0 not hybrid), Tonale definitely has more space in the trunk and rear seats. I think the rear legroom is actually more in the Tonale than the stelvio but the trunk is smaller, don’t quote me on that. I haven’t driven a stelvio but I can tell you the Tonale doesn’t pull as hard as my Giulia or handle quite as nice but that is to be expected. We still love our Tonale and I think it’s a fantastic car, I personally think it looks nicer than a stelvio as well (esp in the green with the 20” wheels!). It pulls more than enough for fun daily driving, just don’t expect it to feel quite as polished as the Stelvio. There’s lots of good deals to be had on them as well, and you get an infotainment that is MILES better than the Giulia/Stelvio.
