The 3.0-liter V6 EcoDiesel-powered 2014 Ram 1500 pickup (earlier post) has earned a 28-mpg (8.4 l/100 km) rating from the US Environmental Protection Agency (EPA)—the best highway-cycle test result achieved yet by a full-size, half-ton pickup. It also exceeds the EPA highway rating for the top-ranked small pickup. The combined city/highway rating is 23 mpg (10.2 l/100 km.)
On the gasoline side, the 2013 Ram 1500 equipped with a 3.6-liter Pentastar V-6 gasoline engine earned 25 mpg (9.4 l/100 km) 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 EcoDiesel is currently the 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 N·m), not matched by full-size trucks equipped with V-6 engines. Towing capacity is 9,200 pounds (4,173 kg).
The all-new engine’s block and bedplate are made from lightweight Compacted Graphite Iron (CGI). Its performance is enhanced by the 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 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.
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.
Other key efficiency features include:
Active grille shutters that optimize air flow for improved aerodynamics;
Electric Power Steering (EPS), which relieves the engine from constantly turning a hydraulic pump; and
Material-use strategies that leverage lightweight aluminum for components such as hoods that do not compromise capability.
Pricing for the 2014 Ram 1500 starts at $24,200, plus $1,195 destination. The exclusive V-6 EcoDiesel with TorqueFlite eight-speed automatic transmission is priced $2,850 greater than a similarly equipped Ram 1500 with a 5.7-liter HEMI V-8 with TorqueFlite 8-speed transmission. Ordering for EcoDiesel models begins 7 Feb.
