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.

NHTSA investigates FCA for SUVs that roll out of Park

The National Highway Traffic Safety Administration is opening a preliminary evaluation into the 2014 Dodge Durango and 2014-205 Jeep Grand Cherokee after 14 complaints of the SUVs rolling out of Park. An estimated 408,000 of them could be affected, if a recall is necessary. All of the current complaints submitted to NHTSA about the issue concern the Grand Cherokee, and the claims allege that the SUV can roll out of Park whether or not the engine is running. Some folks report that they check the indicator each time because the gear sometimes fails to engage. Among the 14 cases, there are five accounts of crashes and three injuries, including a situation with someone allegedly being rolled over. NHTSA's preliminary evaluations are meant to investigate "the scope, frequency, and safety-related consequence" of a reported problem. They don't necessarily lead to a recall.

The unintended motion has occurred with both the engine off and the engine running. ODI has also identified EWR field report data related to the alleged defect. The model year 2014 and 2015 Jeep Grand Cherokee vehicles are equipped with an electronic gear selector (shift-by-wire system). The gear selection is made by pressing the shifter-paddle forward or backwards; the shifter does not move along a gate path as with conventional gear selectors. A Preliminary Evaluation has been opened to asses the scope, frequency, and safety-related consequence of the alleged defect. The VOQs associated with the opening of this investigation are: 10733158, 10730952, 10683556, 10679497, 10583366, 10725429, 10715401, 10711893, 10676998, 10668651, 10662619, 10662308, 10605865, and 10567538.

Jeep Wrangler likely to get aluminum body, will stay in Toledo

Perhaps more than any other vehicle currently for sale in the United States, the Jeep Wrangler is viewed by purist fans as a vehicle that simply must maintain the status quo. In this case, that means a body-on-frame design, solid axles, a relatively large engine sitting up front and a removable top. It's always been that way, and it always will be.
Maybe.
According to the most recent reports, the next-generation Jeep will continue to soldier forth with a full steel chassis underneath its stamped bodywork. The biggest change, reports Automotive News, will be that said panels will be hewn from aluminum instead of steel, a seismic shift of a transition not unlike what's happened with the new Ford F-150. Because it won't be a unibody, the SUV will likely continue to be assembled in Toledo, OH as it (almost) always has been - the latter has been a source of heartburn in recent weeks for the Northwestern city in the Buckeye State.
