Inline-6 Hemi replacement on the cusp of production from Stellantis

It appears that Stellantis is ready to put its long-rumored inline-six into production at its Saltillo, Mexico plant, possibly marking the beginning of the end of Chrysler's long-running 5.7L Hemi V8. But so far, the automaker's American brands have remained mum on where exactly the new turbocharged "Tornado" I6 may land. Stellantis powertrain blog Stellpower (by way of Muscle Cars & Trucks) spotted an entry for a new "GME T6" inline-six engine on the Saltillo facility's web site, suggesting that it was either in production or close to it. That entry has since been removed, but the mystery remains.  We've been hearing tidbits here and there about this new inline engine for years, but this is the first time we've seen anything suggesting its arrival is imminent. Usually, such a significant powertrain update would coincide with the launch of a new product to showcase it. So far, Stellantis has remained mum, even overseas, about where this engine is destined to reside. 2022 model year vehicles are likely off the table entirely.  But while it's common for new engines to debut with new cars and trucks, it's not a universal truth. Ford's Coyote V8 missed the corresponding Mustang refresh by a year, for example, orphaning the 2010 model and its much-needed styling updates with the old 4.6L V8 (and the 3.8L V6, for that matter; the 3.7L Duratec was also late to that party). Even sticking just to Stellantis, the JL Wrangler's powertrains have been a work in progress since it arrived back in 2018. The standard V6 and 2.0-liter turbo-4 debuted at launch; the EcoDiesel, 392 and 4xe all came later.  And 4xe may be the model by which to measure our expectations. Its introduction didn't come completely out of nowhere, but it was rather sudden for what turned out to be such a solid offering. That bodes well for the company's existing Hemi-powered trucks and SUVs. The Ram 1500, Jeep Grand Cherokee and Wagoneer are all strong candidates to receive the new Hemi replacement, as all would greatly benefit from even small improvements in fuel economy. If there's to be a future for the Dodge Charger and Challenger and Chrysler 300, they'd benefit too. And how about a Gladiator with the wick turned up, positioned as its equivalent to the Wrangler 392. Turn that Tornado into a Dust Devil. Don't worry; we've got plenty more where that came from.  Related Video This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings.

2017 Dodge Durango GT Brass Monkey: A funky winter drive

The 2017 Dodge Durango is one of our favorite sport utility vehicles. It has power and style and it stands out in a segment that is filled with vanilla-flavored people haulers. We recently had a Durango GT outfitted in Brass Monkey trim – highlighted by its 20-inch burnished bronze aluminum wheels - and took to the back roads of Michigan for an extended drive. The snow was flying. The temperatures dropped. It was muddy. The unpaved roads, pocked and rutted, were jarring, even though the forested setting was serene. The Durango had no trouble with any of it. Watch our video review for the complete experience.

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".
