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.

Chrysler recalling 280k Dodge Ram 1500 pickups over axle seizures

Following a June investigation by the National Highway Traffic Safety Administration, Fiat Chrysler Automobiles will be recalling 280,000 Dodge Ram pickups from model year 2005. The issue, NHTSA told The Detroit News, centered on a loose pinion nut, which could cause the rear axle to seize and, potentially, the driveshaft to detach. The affected vehicles were built between January of 2004 and August of 2005, while of the 280,000 trucks, only 257,000 were sold in the US market. According to The News, the recall will begin on February 13, and will see owners report to dealerships to have "a retention feature" added to the pinion nut.

Dodge Viper plant will close for good Aug. 31

It has been a long time coming, an end rumored since at least 2015, but after 25 years, the Dodge Viper's demise is nigh. Production of the $90,000 bespoke sports car is ending. Therefore, FCA will be shutting down its Conner Assembly Plant on Aug. 31. Automotive News reports that the Detroit plant will be shutting down. The car has been hand-built there since 1995, save for a hiatus in 2010-13 (production began at FCA's Mack Plant in 1992). The Prowler was built there, too, from 1997 to 2002. More than 80 workers currently build the Viper, making Conner FCA's smallest assembly facility. But not many Vipers are sold - 630 last year - despite an enthusiastic following. And of course FCA's own 707-horsepower Dodge Challenger and Charger SRT Hellcats and new 840-horsepower Challenger SRT Demon can't help matters. But the last straw is the fact the Viper can't comply with new safety requirements going into effect. On the bright side, the UAW has seen the plant closure coming since 2015, and FCA has told the state of Michigan that it expects to find positions at other plants for the Viper crew. FCA has been celebrating the Viper valedictory for a couple of years now, offering serialized special editions, including the $121,000 Viper ACR, and touting the ability to build unique Vipers with its "1 of 1" customization program, with a choice of 16,000 unique paint colors and 48,000 unique stripe combinations.
