Re-engineered Ram

Thermal management-along with other significant changes-improves Ram 1500 fuel economy and earns EPA off-cycle credits.

Thermal management isn't a new frontier for improved fuel economy, but automakers are finding that seemingly small changes add up and that system integration provides opportunities to do more with less.

The 2013 Ram 1500 pickup HFE (high fuel efficiency) uses a host of effective ways to get class-leading truck fuel economy, and the U.S EPA window sticker numbers are impressive: 18 mpg city, 25 mpg highway for the 3.6-L V6 with idle-stop and eight-speed automatic-a 20% improvement over the previous model. The standard V6/eight-speed model (without idle-stop) is close: 17 mpg city/25 mpg highway.
