As much as we like Ram's available 3.6-liter V6 and 5.7-liter V8 gasoline engines, the 3.0-liter V6 diesel engine is the one to get. We've now spent eight months with our 2014 Ram 1500 EcoDiesel and it's the quietest example in the full-size truck segment. Other competitors might object to this claim as the Chevrolet Silverado is also very quiet from the inside but it doesn't offer the fuel efficiency of a diesel engine (yet). The Ram's diesel engine puts the 1500 over the top in terms of keeping everything quiet no matter what speed or surface you're traveling.

Silence is golden

We outfitted our long-term Ram 1500 in the Laramie trim and after a long day at the office or on the job site, it's a nice place to spend during the ride home. With over 18,000 miles on the odometer (and a trip to the east coast and back) under its belt we're surprised at how quiet the Ram's interior continues to be. The Ram 1500's interior is serene even as traffic on Interstate 405 continuously stacks up outside so much so that even the calmest of people lose their cool. But you can avoid that by simply engaging automatic climate control, tuning to your favorite radio station, and watching the world quietly shuffle around you. The only thing we're not crazy about is when the drawer underneath the center stack is fully extended and filled with the contents of your pockets; it tends to bounce around a bit and, in turn, makes an annoying rattling noise.

Not your father's diesel engine

As we said before, Ram's EcoDiesel engine is so quiet you can barely hear it over the radio when it's running. It takes a second for the engine to start up but after a gentle shudder you're ready to go. At idle, the engine is equally subdued and not at all like heavy duty truck engines that make their presences known through both sound and smell. The 3.0-liter V6 is only noticeable when you forcefully apply the throttle when accelerating to highway speeds. Once there, the transmission and engine work seamlessly and from the cabin you can't hear much coming from the drivetrain. Like all tires, the Ram's rubber sings a different tune depending on the road surface below but it's never overwhelmingly annoying.

Bottom line 

Demand for Ram trucks equipped with the 3.0-liter V6 EcoDiesel engine has continued to rise without an end in sight. This, in part, is because of how seamless this drivetrain integrates with the truck. While the diesel is a $4,500 option, it'll make up the difference in cost savings at the pump in no time. The EPA rates this engine to achieve 20 city/28 highway/23 mpg combined but we've seen these numbers eclipsed regularly. Pair that with a whisper quiet interior and you've got yourself a segment leader.
