My primary concern about the new 200 isn't how it looks, it's how big it is. Chrysler is the only manufacturer that is basing their mid-size offering on a platform that has been reserved for smaller vehicles. It will be on the same platform as the Dart, which was upsized from the even smaller Giulietta.
I say this is a concern because there is another car that shrunk during it's latest refresh and it has since been quite a dud: Malibu. During the 2013 refresh, the Malibu width increased by 3 inches, but it's wheelbase shrank by 5. It was largely panned by critics, with much ire being directed toward interior space, especially in the rear seats, which is a direct result of the wheelbase reduction. A big focus of the 2014 scramble refresh was re-contouring the seats to increase rear seat legroom.
Contrast this to the Fusion, which did just the opposite of the Malibu: The 2013 refresh *increased* the wheelbase by 5 inches. An out-of-the-park sales hit, few of the press reviews have mentioned interior space as a downfall.
I know that Fiat says the Compact Wide platform will scale to mid-size, I just don't take much solace in their opinion, especially in a segment as competitive as mid-size cars. While the heavily sloped rear greenhouse looks great, it does no favors for rear occupant headroom. Couple this with their previous two challenging launches of the platform and they have an uphill battle. The Dart was launched with completely wrong powertrain options and has largely been a segment back-marker and the Cherokee has had the infamous transmission concerns. If the 200 launch is plagued by half the problems the Dart or Cherokee has had, it'll be DOA.
