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.

Ram issues recall on heavy-duty pickup transfer cases

UPDATE: A previous version of this story said the issue only occurred in four-wheel drive. This is incorrect – issues are only exhibited in two-wheel drive. The Basics: Ram is recalling 930 3500, 4500, and 5500 heavy-duty pickups from model year 2016. The affected 3500s were built between July 24, 2015 and January 7, 2016, while the larger 4500/5500 trucks were screwed together between July 24, 2015 and October 8, 2015. The Problem: According to the official NHTSA bulletin, the "transfer case may have been manufactured with a misshapen main output shaft, creating voids that may cause a shaft fracture." If this happens, the vehicle could lose power. The driver might not be able to select park, either. Injuries/Deaths: FCA isn't aware of any injuries or deaths related to the issue. The Fix: Dealerships will replace the transfer case on affected trucks. If you own one: You probably don't. According to FCA spokesman Eric Mayne, dealers haven't delivered the majority of the affected trucks to customers. But if you really do own one, Mayne added that the issue only occurs in two-wheel drive. We'd advise keeping it in four-wheel drive until you can report to your local dealer. FCA kicked the recall off on August 10, so expect a mailed notification soon. Related Video:

Chrysler recalls AWD 300, Charger, Ram 1500 over ZF transmission

What do the Chrysler 300, Dodge Charger and Ram 1500 all have in common? Yes, they're all Chrysler products, and two of them are based on the same platform. And we're sure you could find more similarities between them all, but the common trait we're looking at here is that, while they all come standard in rear-drive form, they're also available with all-wheel drive. And it's the transmission in those models that's the subject of the latest recall notice issued by the National Highway Traffic Safety Administration.
The output shaft on the eight-speed automatic transmission supplied by ZF to Chrysler for the AWD versions of the 300, Charger and Ram 1500 is apparently prone to fracture. That in the end could leave the vehicle without power and could, according to the NHTSA investigation, increase the chance of a crash. The vehicle could also roll away if even if left in Park without the handbrake applied.
That's why Chrysler is calling in 4,194 examples of those three models from the 2013 model year. Dealers will be responsible for inspecting the transmissions and, where necessary, replace the entire unit. See the full recall notice below for all the details.
