Ram revealed the specs for its updated EcoDiesel V6 engine in the 1500 this week. The big news is 480 ft-lb of torque in a light-duty truck. Towing is also very impressive with towing up to 12,560 pounds. Finally, Ram says that it expects to also have class-leading fuel economy from its 3.0-liter turbo-diesel engine-equipped truck.
"The new Ram 1500 EcoDiesel is America’s most powerful half-ton diesel pickup, following up on Ram’s Heavy Duty torque leadership and achieving what no other manufacturer has, with up to 480 lb.-ft. of torque in a 3.0-liter engine,” said Reid Bigland, Head of Ram Brand. “The all-new EcoDiesel engine and our eTorque mild-hybrid powertrain technologies deliver the highest available fuel efficiency for our Ram 1500 customers.”
Ram says it will also pair its diesel with the only air suspension in the class. Being able to lower the truck at highway speeds will likely help with fuel efficiency. Ram's new 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 compacted graphite iron, which Ram says provides strength to dampen vibrations, but weighs less than grey cast iron. Ram uses a compacted graphite iron bedplate to add rigidity to the block. The new EcoDiesel has a forged steel crankshaft and connecting rods for strength and durability. Ram's aluminum alloy pistons are cooled on the underside via oil jets. Heat-treated aluminum cylinder heads have individual bearing caps to reduce friction and minimize NVH. The engine's chain-driven overhead camshafts employ roller-finger followers.
Ram pointed to these specific upgrades as significant:
-A new-generation water-cooled turbocharger with variable geometry turbine (VGT) increases efficiency and responsiveness during transient conditions
-Redesigned cylinder head intake ports improve swirl and flow, increasing performance and fuel economy
-The exhaust gas recirculation (EGR) system design has been updated to a dual loop (low and high pressure) system. The added low-pressure circulation system draws gases after the diesel particulate filter, thus minimizing turbocharger energy losses, which increases fuel economy
-The compression ratio has been optimized to 16.0:1 from 16.5:1
-High-pressure (29,000 psi/2,000 bar) direct-injection fuel injector nozzles were redesigned to match the newly designed and optimized combustion chamber
-Lightweight aluminum alloy pistons were completely redesigned to include thinner rings and low-friction coating on the pin and side skirts to reduce losses
-NVH has been reduced by offsetting piston pin by 0.3 millimeters from the centerline; thus, minimizing mechanical noises
-The lower portion of the two-piece oil sump uses a lightweight sandwiched polymer/metal material that further reduces NVH
-The dual vacuum pump system uses electric and a new mechanical low-friction pump with new blades that improve overall system efficiency
Ram will not build this engine in the United States. Rather, it will be produced FCA Cento facility in Ferrara, Italy and imported. Watch for price and fuel efficiency new in about two months. The engine will be available in Ram trucks starting this early winter of 2019 unless it is delayed for emissions testing or other reasons.
I purchased my truck a few months ago and most of the time i need to press the button 2-5 times to drop my tailgate without any help. With a little (and i mean 5 lbs) of pulling while pressing the button it works most of the time, even then i might have to press it twice. The truck is a new body 2019 Silverado LT 4x4. It started doing this day one, i thought it might just need to work in/break in and it did not.
Is anyone else having this issue?
If so do you know how to fix it?
I have tried with the vehicle on level ground and even then it does not work all the time also i tried it on grounds where the front is up a few inches and i would still have to press at least twice. Every 50 times or so it will go down with one press.
Any help will be appreciated.
I have received a small dimple on my 2 month old Denali Tailgate. It appears to be plastic. No paint damage, just a small dimple. I had a few shops look at it, and they didn't want to touch it. I was going to hit it with a heat gun and press it out, but not sure about that. I was hoping I was not the first one to have this issue.
Its over towards the right, just by the reverse light.
Is there any preventative maintenance that can be done with the tailgate latch? Mine ‘18 seems to be getting a little tough to open and although it’s under warranty I thought if I could lube, grease, silicone, spit on, or whatever it takes to loosen it up it’d be nice.
Thank you for your consideration and as a side note I will not be having a garage sale this weekend.
