Sedan vs wagon dynamics

[Biggoggs]

Hey guys, I've been trying to decide how the wagons perform dynamically in comparison to their sedan counterparts. Despite being 20cm longer, 45cm higher, and have ~22cm longer wheelbase, they're only 90kg heavier, the same as having a chunky passenger. Psychologically, a wagon would feel much bigger and heavier as a sedan is more an enclosed space, and the rear leaf wouldn't be as independant as a coil, but aside from that I can't see any major differences in performance.

I don't see how they're apparently 40cm thinner in width though. According to the stats I'm going on, it has the same interior room (although more front & back headroom), must be something with the bodywork.
