A couple of people here thought that it would be competing with the Mondeo/Laguna/406 etc.
It won't. That's the Regata/Tempra/Marea-size, this one is supposed to replace the Croma. I used to have a Croma - it was a large car, tall and spacious, solid-feeling, the same size as a Saab 9000, of course because most of the bodywork was the same. That means it was bigger and more upmarket than a Sierra wagon, Mazda 626, Toyota Corona, etc.
The thing is, the Croma had a family resemblance to the Uno, but larger and therefore (in my eyes anyway) more elegant. It had a few soft edges blended into the style (e.g. the bonnet wrapping over the front wings, a soft edge to the tailgate) at a time when 80's cars were all about hard folded edges. The 'executive hatchback' was a new thing indeed.
I don't see this new 'Croma' having any resemblance to other FIATs. It looks more like a Toyota or a Honda to me, particularly with those straight-across rear lights (Camry?) It also looks undeniably like a wagon (sorry, estate car) which makes it seem a bit frumpy to me - no trim elegance in this one. When BMW have made 'executive estate cars' they've made them a bit slimmer than this!
Just in case you've forgotten what a Croma looked like, I've attached some pics.
