I like the increased windshield rake, and how they lowered the door shoulders to allow for a less slab-sided look, with a little more glass. There is a nice, slightly upward sweeping character line. From the side, it looks a little more like a Cadillac (not a bad thing), while the front is distinctly Chrysler.
The interior is much nicer looking as well.
In my opinion, this is a good redesign of Chrysler's flagship.
Where Chrysler will be challenged for a while yet is in the powertrain department. The new Phoenix V6 will bring much needed refinement and better fuel economy, but the rumor at Allpar is that the 300C will probably launch with a Mercedes sourced 5-speed automatic transmission, when the fuel economy leaders are getting into 6 speed transmissions. Will Chrysler have the money to outsource a 6 or 7 speed auto? Consider that the closest competitor to the 300C at Ford, the Taurus, gets EPA combined 22mpg with a 6spd auto, while the Cadillac STS gets 21mpg combined, also with a 6 speed auto. Toyota's Avalon gets 23mpg from a 6 speed.
