Thanks to the eight-speed automatic transmission and V-6 that's essentially the base powertrain for retail models of the 2013 Chrysler 300, this is a surprisingly fuel-efficient sedan, with EPA numbers of 19 mpg city, 31 highway in rear-wheel-drive form.
All-wheel drive drops ratings to 18/27 mpg, although Chrysler boasts that these are best-in-class models. 300C HEMI V-8 models earn highway numbers of up to 25 mpg. Although due to so-called Fuel Saver Technology (cylinder deactivation), you may see even better, as we have, if you can use some self control and keep your right foot light.
EPA ratings for the SRT8, with a city rating of just 14 mpg, seem right on the mark, if even a bit optimistic, based on what we've seen. This is a performance model best enjoyed by those who know exactly what they're getting--a blast-from-the-past, large-displacement V-8 engine with a potentially budget-busting thirst.
Conclusion
V-6 versions of the 2013 Chrysler 300 are quite efficient compared to large luxury sedans, but Hemi V-8-powered versions are guzzlers.
