The EcoDiesel-powered 2014 Ram 1500 has earned a 28-mpg rating from the U.S. Environmental Protection Agency (EPA), the best highway-cycle test result ever achieved by a full-size, half-ton pickup.
It also exceeds the EPA highway rating for the top-ranked small pickup.
The breakthrough results mean Ram keeps the half-ton fuel-economy record set last year by the 2013 Ram 1500. Equipped with a 3.6-liter Pentastar V-6 gasoline engine, the truck earned 25 mpg highway, a rating that stands for model-year 2014.
The Ram 1500 now owns the half-ton pickup segment’s top two spots in the EPA’s 2014 highway fuel-economy rankings.
“The new Ram 1500 EcoDiesel is truly in a class of it’s own with 28 MPG and the ability to tow 9200 pounds,” says Reid Bigland, President and CEO Ram Truck Brand. “To put the Ram 1500 EcoDiesel in context, it gets 6 mpg better fuel economy than the best F150 Eco-Boost. Overall, the Ram 1500 Eco-Diesel has outstanding pick-up truck capability with compact-car-like fuel economy.”
The EcoDiesel is the first and only advanced-technology turbo-diesel offering in the half-ton pickup segment. In addition to superior fuel economy, it delivers peak torque of 420 lb.-ft. (569 Nm), which is unsurpassed among full-size trucks equipped with V-6 engines.
The all-new engine’s block and bedplate are made from lightweight Compacted Graphite Iron (CGI). Its performance is enhanced by the innovative MultiJet 2 common-rail fuel-injection system, which is exclusive in North America to Chrysler Group.
MultiJet 2’s high-dispersion nozzles and advanced-technology servovalve can accommodate up to eight fuel-injection events per cylinder cycle. This mitigates noise and improves low-speed throttle response, while also reducing fuel consumption and emissions.
The all-new 3.0-liter EcoDiesel features state-of-the-art Selective Catalytic Reduction (SCR), high-pressure cooled Exhaust Gas Recirculation (EGR), variable swirl intake ports and a variable-geometry turbocharger. All contribute to 50-state compliance with Tier 2-Bin 5/LEV II emissions regulations.
Named one of Ward’s 10 Best Engines for 2014, the EcoDiesel V-6 was a significant factor in the Ram 1500’s selection as 2014 Motor Trend Truck of the Year. The Ram 1500 is the first vehicle to win this prestigious award in back to back years.
Chrysler Group’s segment-exclusive TorqueFlite 8-speed automatic transmission further improves the Ram 1500’s fuel efficiency. While enabling optimal engine speed in a wide range of driving conditions, the advanced-technology gearbox benefits from a thermal-management system that quickly warms transmission oil to reduce pumping losses associated with cold, low-viscosity fluid.
