Fiat Chrysler working on an inline-six to replace the Pentastar V6?

Get out your Skeptics Hat for this one and keep it close by. Allpar cites "reliable sources" to write that Fiat Chrysler appears to be working on a new inline-six engine to be slotted into company products around the globe. The purported engine would be based on the 2.0-liter Global Medium Engine inline-four. Allpar first reported on the potential development in February 2017 and has filed a few updates since then, one citing "internal communications referring to a GME T6" — the "T" meaning turbocharged. It's said that some engineers have changed their online resumes to reflect their focus on the new motor. Apparently, FCA tried adding forced induction to the Pentastar V6 but didn't like the results. The new direction then turned toward a "compact straight-six." In at least one guise, the GME I-6 would come in at just under three liters in order to escape taxes on engines 3.0-liters and above in certain European markets; the 2.0-liter four-cylinder has an actual displacement of 1.995 liters. The present V6 Pentastar comes in 3.2-liter and 3.6-liter guises; a turbocharged 3.0-liter straight-six should be able to replace both as far as output. Hooking up to the company's eTorque system used on the 3.6-liter Pentastar and 5.7-liter Hemi would make things even more punchy. With the trend in truck engine downsizing, it wouldn't be crazy to see such an engine head straight to Ram. The four-cylinder GME unit serves in the Alfa Romeo Giulia and Stelvio, and Jeep Cherokee, Wrangler, and Grand Commander. The big Alfa Romeos and full-size Jeep and Ram models shouldn't have any problem with a longer inline engine. Maserati, which doesn't use the Pentastar engine, could be a candidate as well should it choose to step away from its Ferrari-developed engine cred. Speaking of Ferrari, the Italian brand is working up a new V6 based, in its words, on "a very, very particular architecture." It isn't clear where it will go or if one of the other Italian brands will get access to it, but the Allpar piece says the Ferrari V6 will be based on the core GME architecture for Maserati. Chrysler gave up its last inline-six 11 years ago when the 4.0-liter I-6 retired alongside the JK-series Jeep Wrangler. The engine format is back in vogue, and its reincarnations have received good reviews. But inline-sixes are generally longer, hence FCA's focus on a compact unit, and that could limit the purported engine's placement options.

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!

Jeep Wrangler diesel likely after 2015 model refresh

We automotive journalists aren't always the right people to ask about whether a US-spec vehicle should or should not be offered with a diesel powertrain (hint: the answer is usually "YES"). But when it comes to the iconic, off-road-ready Jeep Wrangler, we aren't the only ones who have been clamoring for an oil-burning engine behind that famous seven-slat grille. To that end, it appears there's good news on the horizon, as Jeep CEO Mike Manley recently told Ward's Auto that the "Wrangler is on the radar to get (a) diesel."
"I'm confident that the Grand Cherokee will show just how large a demand there is for diesel, and I think what that will do is reinforce the need for us to target Wrangler as a vehicle that can take a diesel," Manley told Ward's. The most rugged of Jeeps is scheduled to get an overhaul around 2015-16, and the diesel powertrain will likely be introduced around that time.
This year alone, Chrysler will be adding a diesel engine to the Grand Cherokee SUV, as well as the Ram 1500 pickup and Promaster utility van.
