If I were Sergio, I'd skip a few steps and rush the thing into production ASAP as a premium sport crossover.
I mean, there's a very clear business case for that, right? Neither Maserati, nor Alfa, or Fiat have a truly premium crossover offering. Clearly, its where the money is going, and there's definitely space for an awkward sporty thing - The Juke, SQ3, and so on are selling quite well. So, why not take the 500X, tweak the interior and exterior for luxurious upgrades. Strap a healthy tune on the 1.4T, push the power well north of 200 BHP, and use that seemingly heavier duty manual/AWD combo from the Renegade underneath. Wouldn't that make more sense than something completely bespoke instead of hemorrhaging more money?
Furthermore, if they want to make a Stratos or a 037 successor, why not tweak what they already have with the Alfa 4C? Its a great chassis, with a great transmission - there's gotta be a way they can figure out how to strap in a different/bigger engine. What about that itty-bitty V6 from the Cherokee? Its all doable, someone's just gotta pull the trigger.
