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 recalls 570,000 SUVs from Jeep and Dodge over fire woes

Fiat Chrysler US has issued two recalls covering a total of about 570,000 Jeep and Dodge models. The first concerns vanity mirror wiring in the Jeep Grand Cherokee from the 2011 and 2012 model years, and in Dodge Durango units built before September 12, 2012. The automaker recalled almost 900,000 units last year to repair the issue, then faced more issues this year when the fires continued in repaired vehicles. This new recall seeks to resolve the issue, FCA saying that the post-recall fires happened in a tiny percentage of vehicles equipped with a specific wiring package. This recall is for 352,831 total units in the US, another 26,478 in Canada, 13,037 in Mexico, and 84,330 internationally. No injuries or deaths have been reported. FCA says it will inform customers as to when they can schedule a service visit to remedy the issue. The second recall takes aim at 60,107 examples of the Jeep Compass and Patriot from the 2015 model year in the US, plus 5,755 in Canada, 3,351 in Mexico, and 23,995 in other markets. Those models could suffer from an out-of-position clamp on the power steering fluid line. The error could allow fluid to leak, increasing the risk of a fire if the fluid ends up on a hot surface. In the case of a complete loss of fluid, drivers will need to use a lot more effort to steer. The automaker reports no injuries or accidents, and will advise customers when to head to the dealer for service.
