New pricing details to pass along for the 2020 Ram 1500 3.0-liter V6 EcoDiesel, which will be available across the 1500 lineup including on the Ram Rebel for the first time. Pricing starts from $38,585 for the Tradesman Quad Cab 2WD, including destination charges.
"The Ram 1500 EcoDiesel offers the best torque and towing among all half-ton diesel trucks," said Reid Bigland, Head of Ram Brand. "Now with a 10-year track record, the Ram brand has emerged as a truck powertrain technology leader. Overall, the Ram 1500 EcoDiesel has outstanding pick-up truck capability and is truly in a class of its own."
The 2020 Ram 1500 EcoDiesel is available across all models and configurations, including a first-time offering in the Ram Rebel.
The EcoDiesel is a $4,995 option, or $3,000 premium over the 5.7-liter HEMI V-8 eTorque ($3,300 on Tradesman, Big Horn/Lone Star, Rebel and Laramie base models). The 2019 Ram 1500 Classic is also offered with the second-generation 3.0-liter EcoDiesel. Itís priced slightly higher starting from $40,835 including destination.
All-new EcoDiesel engine
Ram says the third generation of the turbocharged EcoDiesel V-6 delivers increased torque and horsepower. Itís rated at a best-in-class 480 lb.-ft. of torque at 1,600 rpm, a 14 percent increase from the previous-generation EcoDiesel V-6, which peaks 400 rpm earlier. Horsepower increases 8 percent to 260-horses at 3,600 rpm.
Several significant changes contribute to the new EcoDiesel's improved dynamic and fuel economy performance:
A new-generation water-cooled turbocharger with variable geometry is more efficient and provides improved response as engine rpms rise and fall
Redesigned intake ports to improve engine performance and fuel economy
Introduction of a dual, high-pressure and low-pressure exhaust gas recirculation system, a first for a diesel engine in North America. The EcoDiesel's existing high-pressure EGR, with cooling exhaust gases drawn from the exhaust manifold, is augmented with a low-pressure EGR system that draws exhaust gases after they exit the diesel particulate filter. The addition of cooler, low-pressure exhaust gas makes a significant contribution to improved fuel economy and lower oxides of nitrogen (NOx)
The compression ratio is changed to 16.0:1 from 16.5:1, which helps reduce exhaust emissions, particularly NOx
Combustion chamber geometry optimized to improve fuel economy
Redesigned aluminum-alloy pistons improve fuel economy. The redesigned pistons use thinner piston rings and coating on the side skits to reduce friction
The piston pin is offset 0.3 degrees from the centerline to reduce "piston slap" against the cylinder wall, minimizing NVH
The lower portion of the two-piece oil sump uses a sandwiched polymer/metal material to reduce NVH
The Selective Catalytic Reduction (SCR) system is 50 percent larger and incorporates a new-generation diesel oxidation catalyst with the Diesel Exhaust Fluid (DEF) system to reduce NOx
New-generation brake system vacuum pump with low-friction blades contributes to improved fuel economy
Built in Italy, Ram Trucks says the 3.0-liter EcoDiesel V-6 uses dual overhead camshafts (DOHC) with four valves per cylinder and a 60-degree angle between the cylinder banks. The block is cast with compacted graphite iron, which provides strength to dampen vibrations, but weighs less than grey cast iron. A compacted graphite iron bedplate adds rigidity to the block.
The EcoDiesel V-6 uses a forged steel crankshaft and connecting rods for strength and durability. The aluminum alloy pistons are cooled on the underside via oil jets. Heat-treated aluminum cylinder heads use individual bearing caps to reduce friction and minimize NVH. The chain-driven overhead camshafts employ roller-finger followers.
Fuel economy ratings will be announced closer to when trucks go on sale early in the fourth quarter of this year.
