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.

Detroit 3 small cars lay an egg in latest Consumer Reports reliability study

Consumer Reports has released its Annual Auto Reliability Survey and the results are, in a word, interesting. While we already covered the score-damaging effects of infotainment systems, there's another big angle to the data that's getting some attention - the utterly dismal scores of the Detroit Three's small car offerings.
The turbocharged Dodge Dart and Chevrolet Cruze, as well as the Ford Fiesta were their respective brands' lowest-scoring models, a stat that's made worse by the fact that the American automakers finished 25th, 21st and 23rd, respectively.
That's not acceptable for The Detroit Free Press' auto critic, Mark Phelan, who has penned a scathing critique of the D3's small car reliability scores, arguing that GM, Ford and Chrysler are "out of excuses."

FCA issues recall for 300k Dodge Chargers over airbag sensor

Fiat Chrysler Automobiles has issued another recall, this time for the Dodge Charger. The issue stems from an overly sensitive control module that could deploy the side-curtain airbag and seatbelt pretensioner if the door is kicked or slammed too hard. The recall affects certain Charger sedans from the 2011-2014 model years, specifically those manufactured between May 6, 2010, and June 5, 2014. All told, that amounts to an estimated 322,078 units, including 284,153 in the United States, another 13,169 in Canada, 2,484 in Mexico, and 22,272 overseas. Owners of those vehicles will be asked to bring their vehicles in to their local dealers to have the Occupant Restraint Control module recalibrated, and are being advised in the meantime to "exercise caution when closing doors." If this issue sounds familiar, that's because the automaker issued a similar recall for Ram trucks just last week, affecting over 667,000 four-door pickups in the United States alone. Following a further investigation into its passenger cars, FCA found a similar problem with the Charger, whose door design mandated specific calibration of the module in question for that model. The company says it is aware of three minor injuries potentially related to the issue, but no accidents. This campaign is just the latest in a string of recall-related issues to have emerged from Auburn Hills recently. The Ram truck recall was issued in tandem with another airbag-related recall for a further million pickups. Prior to that it called in another 1.4 million vehicles to update their infotainment system software due to a security issue. Another 350,000 Dodge Journeys were called in before that to have their engine covers secured. The National Highway Traffic Safety Administration is expected to issue the company a massive hundred-million-dollar fine for failing to follow proper procedures related to safety and recall issues. Meanwhile, another NHTSA investigation that could have affected 4.7 million units was closed with no further action deemed necessary. And an appeal court judge in Georgia reduced the damages the company will be ordered to pay the family of a child who died in a fire in a Jeep Grand Cherokee. Statement: Occupant Restraint Control Module August 1, 2015 , Auburn Hills, Mich. - FCA US LLC is conducting a voluntary safety recall to recalibrate control modules on approximately 284,153 U.S.-market sedans to prevent inadvertent side-curtain air-bag and seatbelt pre-tensioner deployment.
