2015 Dodge Dart 2.4 SXT
With gas prices being what they are, I'm curious as to how well some of you are managing to hypermile. The best I've seen is 5.2L/100km (45MPG). I got a 2015 Dodge Dart SXT 2.4, with a few mods aimed at efficiency. Custom undertray for less drag. Lightweight rims with tires inflated to 40psi. AC system delete. Lightweight crank and water pump pullies. Oil cooler delete. Apart from weight savings, can't think of much else to make it more efficient.
