Four-cylinder versions of the 2014 Chrysler 200 get gas mileage that's surprisingly low. At either 30 or 31 mpg on the highway with the four-cylinder engine, the base engine in the 200 Sedan gets lower mileage than some competing V-6 sedans.
Meanwhile, the V-6 models get 19 mpg city, 29 highway--figures that aren't so bad, yet ones that are far below those of the new Honda Accord V-6, for instance.
Real-world figures have been a bit better, from our experience--especially with the V-6. We saw 24 mpg over about 250 miles of mixed driving in a V-6, while over about 300 miles of mostly gentle highway driving in a four-cylinder Limited sedan with the six-speed automatic, we saw about 27 mpg.
