If you encounter a Chrysler 300 sedan, it is probable that you might not notice a single change, apart from the new grille on the SRT8 model. The interior too was slightly upgraded as the materials used are of a better quality. On the mechanical side, the 5.7-litre V8 engine sees its power output go from 340 to 370 horsepower, while the all-wheel drive versions get a new more efficient transmission system.
