Chrysler has the LX platform, which could potentially be reworked and used for the new Giulia, is being examined as one way to get an Alfa model launched and built in the U.S. without crushing Fiat with shipping and import costs piled on top of being expensive to build in the first place. The LX is heavier than might be ideal, though it has been engineered to support all-wheel drive, and the rear-wheel drive default of the longitudinal powertrain layout is inherently more sporty if tuned properly. Alfa's got its own platform, the C-Evo, which could be bulked up to underpin the Giulia, and it, too, is a front-engined, RWD layout that could potentially bring an appropriately athletic feel.
Neither platform is exactly perfect – both are aging, and the competition in the segment is stiff. The futures of Alfa and Chrysler appear to be intertwined, with both brands relying on the same basic hardware to launch new or updated models that need to be successful for Sergio Marchionne's plan for world domination to actually work.
