Ram 2500 HD video shows off new engine, rear suspension

We've already had a chance to drive the 2014 Ram 3500 HD, but the big news for the 2014 Ram Heavy Duty lineup might be centered around the three-quarter-ton 2500 model. Chrysler has released a new video highlighting the new features of the 2014 Ram 2500 HD, including its new optional engine and new rear suspension components.
The video starts by showing off the Ram's new 410-horsepower 6.4-liter Hemi V8 and then gives us an up-close look at the coil spring, multi-link rear suspension - one of the truck's most important upgrades aimed at delivering a smooth ride. In addition to this coil suspension, the Ram 2500 HD will also be available with a rear air suspension system, which Chrysler says will optimize the truck's hauling abilities with better load leveling and trailer towing.
Scroll down for the walkaround video of the 2500 HD from Chrysler as well as the original press release breaking down all of the truck's new-for-2014 features.

Ram/Jeep Ecodiesel engine has Maserati roots

The 3.0L turbodiesel V6 in the 2014 Ram 1500 EcoDiesel earned a slot on Ward's Automotive 2014 10 Best Engines for its power, fuel economy and refinement. In a piece looking at how Fiat subsidiary VM Motor developed the engine, Ward's also makes note of the fact that the same lump goes in diesel versions of the Maserati Quattroporte and Ghibli. They're tuned a bit differently, naturally, with the QP putting out 275 horsepower and 442 pound-feet of torque, the smaller, lighter Ghibli making do with the same number of horses but a lower torque output of 420 lb-ft.
The 240 horsepower and 420 pound-feet put out by the oil-burning six-cylinder in the Ram was tamed with a host of advances, but it appears that Ram hasn't tamed demand: the initial allocation of 8,000 engines was spoken for within three days of the truck going on sale. Head over to Ward's to read the story of how Ram worked out the equation light-duty-pickup + diesel = success.

Ram boosts Heavy Duty truck claims for 2015 [w/video]

The heavy-duty truck segment boasts some of the tightest competition of any automotive niche in the US. Being able to tout just one best-in-class figure can be a marketing advantage over competitors, and Ram Trucks is adding one more accolade to its tally with a powertrain update for the 2015 Ram 2500 and 3500 Heavy Duty pickups. Ram now claims best-in-class ratings for torque, towing and payload, depending on configuration.
The major change comes for the 3500 HD with a boost in torque for its Cummins 6.7-liter, inline-six diesel engine. It now produces a meaty 865 pound-feet of twist, a boost of 15 lb-ft, which is the best figure in its segment, according to the company. To eek out the extra power, the mill has more aggressive fuel delivery, and the turbo has been recalibrated. Of course, more grunt would be meaningless if drivers couldn't do anything with it, and the tweaks help allow payload to grow to 7,390 pounds, up from a rating of 7,320 pounds last year. The max towing rating remains unchanged at 30,000 pounds, though.
The rest of the powertrain lineup carries over from last year. The base HD mill is the gasoline-fed 5.7-liter V8 with 383 hp and 400 lb-ft and a six-speed automatic. The next step up is a 6.4-liter V8 with 410 hp and 429 lb-ft. There are also three trims of the 6.7-liter Cummins diesel starting with 350 hp and 660 lb-ft with a six-speed manual gearbox. If buyers opt for a the 68RFE six-speed auto, they get 370 hp and 800 lb-ft. Finally, there's the updated, top-rung version with 385 hp and 865 lb-ft with an Aisin six-speed automatic transmission.
