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.

FCA and Cummins named in diesel emissions class-action lawsuit

Chrysler is now the first United States-based carmaker to be sued for allegedly skewing emissions results. In a move that sounds eerily similar to the troubles of European manufacturers, Chrysler is claimed to have hid diesel engine characteristics causing emissions as much as 14 times higher than permitted by regulations. According to Bloomberg, the lawsuit alleges that Chrysler, together with its diesel engine partner Cummins, has concealed the nitrogen oxide output of certain Ram vehicles produced between 2007 and 2012. The NOx pollutants were meant to be broken down in a process called regeneration in the truck's NAC system, or NOx Absorption Catalyst, which predated the 2013-introduced SCR, or Selective Catalytic Reduction system. By design, the NAC captures and stores NOx emissions, converting them to nitrogen and oxygen through a catalytic process. The lawsuit claims the Cummins engine's system has a limited capacity to store the emissions, and as a result the pollutants escape, increasing emissions, worsening fuel consumption and wearing down the catalytic converter. The later, cleaner SCR system uses a urea-water injection, and it gradually replaced the NAC on Cummins 6.7-liter engines, as it was first implemented in 2011 and made standard in 2013. As Bloomberg notes, the model years of Ram trucks involved in the lawsuit predate the earliest Volkswagen "Dieselgate" models by two years. The lawsuit, filed on behalf of 500,000 truck owners, accuses Chrysler and Cummins of fraud, false advertising and racketeering. As an underlying motive, the filing mentions a 2001 change in EPA emissions standards. Announced to become effective in 2010, the EPA requirements drove Chrysler and Cummins to try and reach those already by 2007. However, the NAC system is said to have fallen short of these goals, and the filing claims that Chrysler and Cummins chose to "rig" the engines instead. The affected vehicles predate the 2014 merger of Chrysler and Fiat. FCA US has released a statement regarding the lawsuit, saying it will contest the lawsuit "vigorously".

Hennessey announces Ram 1500 TRX six-wheel conversion

Between the six-wheeled Hennessey VelociRaptor 6x6 and Goliath 6x6 pickup trucks, based on Ford and GM trucks respectively, we should have known a Ram would be next. And Hennessey Performance is pulling the stops out farther than ever before by basing its latest hulk on the 2021 Ram 1500 TRX. Hennessey is calling this six-wheeled beast the Mammoth. But the reason for the name goes beyond the size. The other reason is that the Texas-based tuner is ditching the already potent stock Hellcat engine in favor of the Mopar Hellephant crate engine. The Hellephant is a supercharged 7.0-liter (426-cubic-inch) V8 that in stock tune makes 1,000 horsepower. Hennessey says they'll get 1,200 horsepower out of it. Of course the Mammoth will also feature six-wheel drive, a lengthened frame and bed to accommodate the extra wheels and tires. Off-road suspension, big tires, steel bumpers, auxiliary lights and custom interior will also be on the list of modifications. Hennessey plans to offer the Mammoth for $500,000 and only three will be built. The company will start taking orders on September 4 at noon central time. If you want to place an order, be ready with your phone at the appointed time and call 1-800-897-0426. Related Video: This content is hosted by a third party.
