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.

FCA goes all-in on Jeep and Ram brands on cheap gas bet

It's no surprise that as SUV and truck sales remain strong in the wake of unusually cheap gas, Jeep and Ram sales are taking off. What is a surprise is that FCA CEO Sergio Marchionne thinks that cheap gas will be a "permanent condition," and feels strongly enough about it to change up North American manufacturing plans. Jeep appears to be the biggest beneficiary of the product realignment. In addition to increasing the sales estimates for the brand worldwide upwards to 2 million units a year by 2018, the brand will get a flood of investment for new product and powertrains. Consider the Wrangler Pickup to be part of the salvo, as well as the Grand Wagoneer three-row announced in 2014 as part of the original five-year plan. The Wrangler four-door will get at least two new powertrains, a diesel and mild hybrid version, in its next generation. That mild hybrid powertrain may utilize a 48-volt electrical system like the one that's being developed by Delphi and Bosch – which the suppliers think will be worth a 10 to 15 percent fuel economy gain at a minimum. Down the road, in the 2020s, the Wrangler could adopt a full hybrid system. The diesel powertrain is planned for 2019 or 2020. The Ram 1500 is also pegged to receive a mild hybrid system, again potentially based on 48-volt architecture, sometime after 2020. Lastly, Jeep and Ram will take over some of the production capacity of existing plants. The Sterling Heights, MI, plant that builds the Chrysler 200 will now build the Ram 1500; the Belvidere, IL, facility that produces the Dodge Dart will take over Cherokee output; the big Jeep facility in Toledo, OH, will be used for increased Wrangler demand. In 2015, according to FCA's numbers, car and van demand went down by 10 percent, but SUV demand went up 8 percent and truck demand 2 percent. Considering that these are high-margin vehicles, FCA can't ignore the math. FCA also won't build any new factories to supplement production to meet demand, but instead are reshuffling production priorities. Think of it this way: FCA is gambling on cheap gas being a permanent part of our lives, at least into the 2020s. By doubling down on SUVs and trucks, the company stands to win big, unless a spike in gas prices changes the landscape. FCA isn't talking about a Plan B, so they're all in. It'll be interesting to see how this plays out.
