I will agree that the Cherokee needs to grow, it is too close to the Compass. I'm uncertain about the design though, whilst it is not for everyone, quite some people seem to love it, and I will say it has much better presence in reality than in pictures. But likely some family resemblance to the Compass will come, and won't ruin the general shape, which I like, and that shouldn't be ruined by a wheelbase stretch either.
In non US markets though, it is clearly not big enough for it's price too.
A 7 seat "Explorer" - if it is a enlarged Cherokee or a Pacifica derived Yuntu, is however a logical addition to the lineup.
The Renegade though, as quirky as it is, seems to sell by the ship load, and I think it#s boxy style is a major selling point (It IMO outsells the 500x quite comfortably, at least form how many you see). It also proves what I often want, that small cars need to look fun. And looking at the small cross over segment, even the otherwise design resistant Audi put out a comical Q2, Toyota a CHR that looks weird yet cool and sporty at the same time, and the Nissan Juke was, despite some haters, a runaway success. It seems those small CUVs need to look cute, stylish and slightly weird to be a success. I will even say the Renegade strikes the balance between "weird enough" and "not overdone" perfectly well, and looks like a Jeep.
