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.

Jeep going bigger with new Grand Wagoneer, smaller with sub-Renegade?

The headlines are still rolling in for the new Renegade that Jeep unveiled at the Geneva Motor Show last week, but already reports are surfacing, citing sources within the company, about what Chrysler's iconic off-road brand will do next.
Speaking with Auto Express (whose reports we tend to take with a grain of salt or two), Jeep chief Mike Manley suggested that two courses of action are currently under consideration at Auburn Hills to develop two very different new models - one smaller and one larger than anything Jeep currently makes.
One plan would be to make an SUV or crossover even smaller than the new Renegade, although it isn't immediately clear what platform it would take. The Renegade (pictured above in Trailhawk spec) will be built in Italy alongside Fiat's upcoming 500X, but uses a heavily modified platform. We figure the smaller model, if approved, could base itself on the new Fiat Panda Cross.

Vile Gossip | Adventures in tire testing

Jean Jennings has been writing about cars for more than 30 years, after stints as a taxicab driver and as a mechanic in the Chrysler Proving Grounds Impact Lab. She was a staff writer at Car and Driver magazine, the first executive editor and former president and editor-in-chief of Automobile Magazine , the founder of the blog Jean Knows Cars and former automotive correspondent for Good Morning America . She has lifetime awards from both the Motor Press Guild and the New England Motor Press Association. This is her first column for Autoblog — look for more Vile Gossip in the future. I began writing at Car and Driver magazine back in its golden age in the 1970s, before I'd actually read it. I knew very little about cars. The only magazine I read religiously was Four Wheeler because I owned big trucks and liked to go off-roading with my Chrysler Proving Grounds friends. My vast 10 years of driving experience up to that point (high-speed dirt-road idiot, taxicab driver, Chrysler Proving Grounds test driver) had less bearing on my being hired at Car and Driver than the fact that the editor just wanted to rile up the all-male staff. He didn't need me for that. They were already in full dudgeon when I arrived. They'd just spent a chunk of time testing a stack of tires for their big tire-test issue, and the editor-in-chief was toe-to-toe with the technical editor over the rankings of the top 10 tires. It was loud, and it was angry. I had no idea that car magazines tested tires. Cab driving had led me to believe that airing up a tire and changing a flat was all you needed to know. I changed so many flats on that cab, I eventually wound up in front of a live audience on the " Oprah Winfrey Show" demonstrating my brilliance with a jack and a tire iron. My point, of course, is that tires are more controversial, and also more essential, than you'd think. My other point is that it's good to get worked up about the subject, but not quite so good to let yourself be seen, as I did, on my hands and knees with my ass up in the air on national TV. This is how I prefer to test a tire: First, pick a top brand. Then accept their invitation to try and beat the crap out of their tire. I chose Yokohama, celebrating its 100th anniversary this year. The big news for them was the GEOLANDER M/T G003!
