2018 Ram 3500 Diesel Changes

It’s no secret that Ram has been working on upgrading the heavy-duty lineup, as evidenced by a slew of spy images. As a matter of fact, the company is due to overhaul the entire truck line in the next few years. Following the completely redesigned 1500 that is slated to make its debut as a 2018 model, the Ram Heavy Duty will undergo an overhaul for the same model year. Based on the pictures of a test prototype spotted recently at FCA’s Chelsea Proving Grounds in Michigan, the Ram 2500 and 3500 are about to receive a number of structural and mechanical enhancements. The most significant change will come in the form of a modified 6.7-liter Cummins diesel V6. According to recent reports, the 2018 Ram 3500 is most likely to go on sale in late 2017 or early 2018.

2018 Ram 3500 Upgrades

The latest batch of spy photos showed test mules with vinyl camouflage covering their front fascia, hood and fenders. So, the 2018 Ram 3500 is definitely due to receive visual upgrades, although it seems that the changes are not going to be too radical. The upcoming Ram Heavy Duty will retain the brand’s signature crosshair grille, much to the delight of Ram enthusiasts. Instead, expect to see slightly reshaped front end components that should give this truck a more modern and up-to-date look.


It won’t come as much of a surprise if Ram decides to bring the Heavy Duty range more in line with the upcoming half-ton 1500 pickup, as it is usually the case in this segment. As a result, the refreshed 2500 and 3500 models will sport a more aerodynamic shape than ever before. When it comes to the upcoming HD’s interior design, more substantial reports have yet to come. Some sources have recently suggested that the changes will be mostly subtle, including some new materials and several technological upgrades.

As mentioned, the 2018 Ram 3500 will benefit from an enhanced version of the 6.7-liter Cummins V6. Expect this capable engine to deliver a slightly increased output compared to what the current variant offers. Namely, the outgoing version produces between 350 and 385 horsepower as well as 660 to 900 pound-feet of torque depending on the model. The diesel-powered Cummins will be offered with either a six-speed manual or a six-speed automatic transmission. Those who opt for gasoline powertrains can expect an unchanged 6.4-liter V8 that gives 410 hp and 429 lb-ft, mated exclusively with a six-speed automatic gearbox.


With the latest set of updates for the 2018 MY, the Ram Heavy Duty will set its Ford and Chevy rivals a new challenge. Hopefully, we will be able to share more details on the new Ram 3500 Cummins as soon as they surface in the coming months.
