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.

2017 Challenger, Charger Hellcats recalled for catastrophic oil-line failure

If you own a Hellcat, either a Charger or Challenger, built between Feb. 6, 2017, and May 30, 2017, you may want to consider parking it for a while. The reason for this is NHTSA officially acknowledged a recall from Chrysler for engine oil cooler lines that could fail, leading to major oil loss. Which of course could lead to severe engine damage. According to the recall information, the issue lies in the rubber used in the oil cooler line. Chrysler's testing revealed that the rubber didn't meet the company's criteria. As a result it was able to separate from a crimped aluminum portion of the line, letting oil spill out. The recall goes into effect on Sept. 22, which is when Chrysler will start reaching out to owners to alert them. The company will replace the oil cooler lines free of charge. Owners can call Chrysler's customer service at 1-800-853-1403 with any questions regarding the recall, which has the reference code "T48." Related Video:

Stellantis is official: FCA and PSA merger finally sealed

MILAN — Fiat Chrysler and PSA sealed their long-awaited merger on Saturday to create Stellantis, the world's fourth-largest auto group with deep enough pockets to fund the shift to electric driving and take on bigger rivals Toyota and Volkswagen. It took over a year for the Italian-American and French automakers to finalize the $52 billion deal, during which the global economy was upended by the COVID-19 pandemic. They first announced plans to merge in October 2019, to create a group with annual sales of around 8.1 million vehicles. "The merger between Peugeot S.A. and Fiat Chrysler Automobiles N.V. that will lead the path to the creation of Stellantis N.V. became effective today," the two automakers said in a statement. Shares in Stellantis, which will be headed by current PSA Chief Executive Carlos Tavares, will start trading in Milan and Paris on Monday, and in New York on Tuesday. Now analysts and investors are turning their focus to how Tavares plans to address the huge challenges facing the group – from excess production capacity to a woeful performance in China. Tavares will hold his first press conference as Stellantis CEO on Tuesday, after ringing NYSE's bell with Chairman John Elkann. FCA and PSA have said Stellantis can cut annual costs by over 5 billion euros ($6.1 billion) without plant closures, and investors will be keen for more details on how it will do this. Marco Santino, a partner at consultants Oliver Wyman, said he expected Tavares to disclose the outlines of his action plan soon, but without divulging too many details at first. "He has proven to be the kind of person who prefers action to words, so I don't think he will make loud statements or try to over-sell targets," he said. Like all global automakers, Stellantis needs to invest billions in the years ahead to transform its vehicle range for the electric era. But other pressing tasks loom, including reviving the group's lagging fortunes in China, rationalizing its huge global empire and addressing massive overcapacity. "It will be a step by step process, also to allow the market to better appreciate every single move. I don't think we will have all the details before one year," Santino said.
