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.

1914 Ford Model T at Historic Greenfield Village | AutoblogVR

We drive all of the newest and most sophisticated cars, but a 102-year-old Ford is one of our recent favorites. Senior Editor Alex Kierstein headed to historic Greenfield Village in Dearborn, MI, to learn to drive a Model T in the latest AutoblogVR segment. Kierstein picks up the Model T fairly quickly, despite its controls. Though they were designed more than a century ago to be simple and easy to use, driving a Model T is complicated and counter-intuitive to the modern motorist. But by the end of his lesson, Kierstein has it all figured out and is enjoying himself. In our other new segment, Detroit Manufacturing, Senior Editor Greg Migliore showcases the city''s industrial might. He tours a modern Fiat Chrysler factory that churns out Dodge Durangos and Jeep Grand Cherokees and then wanders the ruins of the mythical Packard Plant. There's also some tasty and unexpected twists in this VR episode. Each week, new episodes will launch on the AutoblogVR App. We'll preview them here on Autoblog, but for the full immersive experience, head over to the app, which you can download for free from the App store and Google Play. Be sure to try it with a cardboard viewer, too! Ford Jeep Automotive History Driving Classics Videos VR Original Video Detroit ford model t tour 360video

Chrysler Recalls Jeep SUVs For Ignition Switches

The ignition switch defects that engulfed General Motors are now a rapidly growing problem at Chrysler. Chrysler said Tuesday it is recalling up to 792,300 older Jeep SUVs worldwide because the ignition switches could fall out of the "run" position, shutting off the engine and disabling air bags as well as power-assisted steering and braking. That's the same problem that has forced GM to recall more than 15 million cars over the last six months. Chrysler's recall covers 2005-2007 Grand Cherokees and 2006-2007 Commanders. The company said it is not sure exactly how many will be recalled, but said it will notify customers by mid-September. Chrysler said an outside force such as a driver's knee can knock switches out of the "run" position. Engineers are working on a fix. The Auburn Hills, Michigan-based automaker, now part of Fiat Chrysler Automobiles NV, said it knows of no related injuries and only one accident. But it said owners should keep clearance between their knees and keys until repairs are made. Chrysler has now recalled more than 1.7 million vehicles for ignition-switch problems. In June, the company added 696,000 minivans and SUVs to a 2011 recall to fix faulty ignition switches. Those recalls covered Dodge Journey SUVs and Chrysler Town & Country, Dodge Caravan and Volkswagen Routan minivans - which Chrysler made for the German automaker - from the 2007 to 2010 model years. Tuesday's recall is the outgrowth of two investigations opened by U.S. safety regulators last month as part of a broader probe into ignition-switch and air-bag problems across the auto industry. The agency wouldn't say Tuesday whether its investigation could lead to recalls at other automakers. The National Highway Traffic Safety Administration said in June that it was investigating Jeep Commanders and Grand Cherokees after getting 32 complaints that a driver's knee can hit the key fob or key chain, causing the ignition switch to move out of position. The federal investigation is still open. The agency said Tuesday that it is requesting additional information from Chrysler to ensure that its repairs will be effective. The investigations and recalls come after GM bungled an ignition-switch recall of older small cars. GM acknowledged that it knew of the ignition problem for more than a decade but failed to recall the cars until earlier this year, when it recalled 2.6 million small cars such as the Chevrolet Cobalt.
