The Chrysler 300 can be surprisingly efficient, thanks to its eight-speed automatic transmission and 3.6-liter V-6. The EPA rates rear-wheel-drive models at 19 mpg city, 31 mpg highway. You lose a bit with all-wheel drive, which earns a rating of 18/27 mpg, respectively.
EPA ratings for the SRT, 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.
Chrysler 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.
