500+ hp Stellantis 'Hurricane' I6 previews a world without Hemis

After years of rumored development, Stellantis has revealed its new six-cylinder engine family. The 3.0-liter, twin-turbocharged "Hurricane" I6 will offer V8 power, forced induction torque and six-cylinder efficiency in a package designed to fit into any of the company's North American rear-wheel-drive platforms.  What is "V8 power," exactly? Well, in standard output guise, the new I6 cranks out more than 400 horsepower (the specific figure will vary by application) and 450 pound-feet of torque, while the high-output variant is good for more than 500 horses and 475 lb-ft. The final figures will be dependent on the application. We'll save you a little legwork: In current Ram, Jeep and Dodge products, the 5.7-liter Hemi tops out at about 395 hp and 410 lb-ft, give or take, and the 6.4-liter around 485 hp and 475 lb-ft.    This is a clean-sheet design that is only related to the company's turbocharged four-cylinder by some common measurements. The I6 is exclusively direct-injection (no hybrid/port-injection here) and the two I6 variants share 96 common parts, including the block and oil pan design. The differences are found in their internals, intake plumbing, valvetrain components and the turbochargers themselves. Stellantis is not yet ready to share specs or supplier info for the turbos but says announcements will come from its partners soon.  The standard-output I6 has a compression ratio of 10.4:1 and revs to 5,800 rpm. It will run on regular fuel, albeit with reduced performance; 91 octane is recommended for maximum output. The high-output variant has a compression ratio of 9.4:1 and will rev to 6,100 rpm. That one will require premium. The new I6's advantages go beyond basic power output. Every Hemi family engine currently in production is based on an iron block design, so they're heavy. The aluminum-block I6 shaves weight off the total engine package, even if some of that gets added back thanks to the turbos and their associated plumbing. The standard-output I6 weighs 430 pounds, Stellantis engineers told us; the high-output adds just another 11. Fully dressed 5.7-liter V8s are in the 550-560-pound ballpark, and 6.4-liters close in on 600 pounds.  You may be wondering, "Why a clean-sheet gasoline engine now, when the industry is moving toward battery-electrics?" A valid inquiry, and one Stellantis was prepared to address. While the company will be pivoting to electrification over the next decade, it won't be instantaneous.

Stellantis not looking for further mergers, including with Renault

MILAN — Stellantis Chairman John Elkann on Monday denied the carmaker was hatching merger plans, responding to press speculation about a possible French-led tie-up with rival Renault. Elkann said that the Peugeot owner, the world's third largest carmaker by sales, was focused on the execution of its long-term business plan. "There is no plan under consideration regarding merger operations with other manufacturers," said Elkann, who also heads Exor, the Agnelli family holding company that is the largest single shareholder in Stellantis. After abandoning the Russian market, at the time its second largest after France, and reducing the scope of its global cooperation with Nissan, Renault has been seen as a potential M&A target. Speculation intensified after an electric vehicle market slowdown forced it last week to cancel IPO plans for its EV and software unit Ampere. Its market cap remains stubbornly low at little over 10 billion euros ($10.8 billion) despite a financial recovery over the past few years. Stellantis, the product of a 2021 merger between France's PSA and Fiat Chrysler and one of the most profitable groups in the industry, has a market cap of more than 85 billion euros when unlisted shares are factored in. It has a 14 brand portfolio also including Citroen, Jeep, Opel and Alfa Romeo. NEWSPAPER REPORT Italian daily Il Messaggero had said on Sunday that the French government, which is Renault's largest shareholder and also has a stake in Stellantis, was studying plans for a merger between the two groups. A spokeswoman for Renault said on Monday the group did not comment on rumors. France's Finance Ministry had declined to comment on Sunday. Stellantis has crossed swords with the Italian government, which has accused it of acting against the national interest on occasions. Industry Minister Adolfo Urso last week raised the prospect of the Italian government taking a stake in Stellantis to help to balance the French influence. Renault shares pared gains after Elkann's comments to stand 1.2% higher by 1220 GMT, having initially risen more than 4%. Stellantis CEO Carlos Tavares, a Portuguese-national, last week said in an interview with Bloomberg that the group was "ready for any kind of consolidation" and that its job was to make sure that it would be "one of the winners". Analysts, however, question the rationale of a Stellantis-Renault merger, which would also expand the group's excess capacity in Europe.

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.
