ram-1500-ecodiesel-hfeThe Ram 1500 EcoDiesel, a model already leading the pickup pack in fuel efficiency, just keeps getting better. The pickup’s new HFE (High Fuel Efficiency) version now bumps up the clean diesel model’s highway fuel economy by another mile per gallon, delivering the highest fuel economy of all current full-size pickups.

Like the standard EcoDiesel model, the HFE’s efficiency is achieved in part by an eight-speed automatic transmission, stop-start system, thermal management system, pulse-width modulation, and active aerodynamics that includes grille shutters and air suspension that lowers the truck at speed for better aerodynamics. The new HFE variant gets a unique trim package and is available with a body-colored fascia adopted from the Ram Express model for a sporty appearance, plus distinguishing HFE badging, of course.
