I don't see why Alfa adopted the current 'round' design, the angular style was perfect.
Blame the 8C. Everyone went nuts for it and Alfa then assumed it would work on anything and everything. I don't
mind current Alfas but I do believe the 8C's owl-face has compromised the design of every single one since it appeared.
The two most beautiful Alfas of recent years have been produced by coachbuilders. The Touring Superleggera Disco Volante, and the Pininfarina 2uettottanta. Neither had the owl face.
That said, I'm not sure the 159/Brera look would necessarily have worked on a car as small as the Mito, or even the Giulietta. It relies on quite long body profiles to carry off the lines, and quite large cars too - partly because that front end is pretty wide. Cramming big car features onto smaller cars never really works, which is why modern Audis look progressively more awkward as they get smaller, to my eyes.
The most-recent, best-looking Alfa?
@ExigeEvan will be pleased to hear it's the GT, for me. Before that, the pre-facelift (pre-Brera-ised) 156.
Alfa needs to go ultra-modern for its future designs, I reckon. Owl-face has too much retro-pandering in it. I'm not saying ditch the heart-shaped grille as that's as much a part of Alfa as the kidney grille is for BMW. But implementing it as a stylistic touch on something with sharp geometric lines, perhaps a shark-nose style like the Montreal (though not directly influenced by it) and make best use of LED technology for a set of ultra-slim headlamps, and that'd work great.
May try and do a few sketches later. The MiTo replacement I have rattling around inside my head looks awesome...
