For 2015, the 200 has adopted a slightly enlarged version of the platform architecture already used for the Dodge Dart and Jeep Cherokee. It’s a more structurally rigid foundation than before and it contributes to a quieter, more refined ride quality. Handling is also impressive for a car in this class. Even better, Chrysler’s midsize sedan gets an upgraded 184-horsepower four-cylinder engine that offers competitive performance for this class — not something we could say about the four-cylinder in the previous-generation 200.
