The Ram 1500 Rebel will be available with an EcoDiesel option for the first time.

The 2020 Ram 1500 with the new 3.0-liter V-6 EcoDiesel engine has a Manufacturer’s Suggested Retail Price (MSRP) starting at $36,890 for the Tradesman Quad Cab 2WD. 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 2020 Ram 1500 EcoDiesel is available across all models and configurations, including a first-time offering in the Ram Rebel.

The Ram 1500’s all-new 3.0-liter V-6 EcoDiesel leads the half-ton pickup truck segment in torque with 480 lb.-ft. and diesel towing capability of 12,560 pounds.

Fuel economy ratings will be announced closer to when trucks go on sale early in the fourth quarter of this year.

Third Generation EcoDiesel Engine Delivers More Torque and Horsepower

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 bed plate 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.

How Did the Ram EcoDiesel Engine Change?

Ram engineers made several improvements in its 3rd generation EcoDiesel Engine:

• A 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 compression ratio is changed to 16.0:1 from 16.5:1, which helps reduce exhaust emissions, particularly NOx
• Redesigned high-pressure (29,000 psi/2,000 bar) direct-injection fuel injector nozzles
• Combustion chamber geometry optimized to improve fuel economy
• Redesigned aluminum-alloy pistons improve fuel economy
• New-generation brake system vacuum pump with low-friction blades contributes to improved fuel economy
