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.

Next Jeep Wrangler to keep solid axles

Jeep fans, you're not out of the woods yet, but the latest news is good: Automotive News reports that the next-generation Wrangler will stick with floating solid axles front and rear. Fiat-Chrysler wouldn't comment on the report, but the theory is that the combination of cost, capability, and ease of modification were deciding factors. We're sure the multibillion dollar aftermarket industry is also pleased. Remember, Jeep showed off the lifted Cherokee Dakar Concept at the Easter Jeep Safari last year, but the first ingredient in the recipe for jacking up its independent suspension was, "a whole new suspension." Above that there will be an aluminum body that's smaller than the current one, which Allpar says could be done with a narrower track and tighter gaps. It will sport a fixed windshield with increased rake to improve aero efficiency, and while there are rumors of a diesel-engined version that we'll finally get in the US, there's been no reliable info as of yet to back that up.

Chrysler accelerates Jeep recall repairs from 2018 to March

You may remember that Jeep's unusual fix for this recall involves fitting a trailer hitch.
The recall of about 1.5 million models of the 2002-2007 Jeep Liberty and 1993-1998 Grand Cherokee over fuel tanks may finish far sooner than originally estimated. In a new filing from Jeep's parent, Chrysler Group, with the National Highway Traffic Safety Administration, the company says that it can complete the repairs for the affected vehicles by March 2015, much sooner than the previous estimate of sometime in 2018. Jeep predicts the total cost of the campaign will be around $151 million.
