Also, I think people assume the Volvo is a lot bigger than it is. It's a competitor to the C Class and 3 Series, not the E and 5, so actually my old E39 had quite a bit bigger boot, and although @mashton made a funny, I think the boot size isn't too different between the Volvo and the Merc that replaced it.
Which is why I think you thought they were bigger, because they filled up the boot, which you assumed to be bigger than it actually is.
The boot is noticeably bigger than in my old e46, and although slightly smaller than the s6 in terms of floor space I think the square back makes a big difference. In my mind. Which is what matters.
I beg to differ, think the V70/850 is a bigger car than that era 3xx /Cxxx/ A4 have you seen the back seats and boot in those? My tape measure shows its 5xx/Exxx/A6 size though not in levels of luxury maybe.
Square back helps it eat things though no matter the floor area.
