All the retail versions of the Chrysler 300 models get a big boost in fuel economy for 2012--thanks to the introduction of a new eight-speed automatic transmission, which yields new EPA numbers of 19 mpg city, 31 highway in rear-wheel-drive form.
All-wheel drive drops ratings to 18/27 mpg, while the 300C HEMI V-8 will earn highway numbers of up to 25 mpg. And you might see even better real-world numbers with the V-8 if you can keep your right foot light, thanks to cylinder deactivation.
SRT8 models provide a thrill and enthusiast appeal unmatched by the rest of the lineup, but it has its costs--namely EPA-rated city fuel economy as low as 14 mpg. And based on our experience with this combination, that's optimistic.
