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 recalls AWD 300, Charger, Ram 1500 over ZF transmission

What do the Chrysler 300, Dodge Charger and Ram 1500 all have in common? Yes, they're all Chrysler products, and two of them are based on the same platform. And we're sure you could find more similarities between them all, but the common trait we're looking at here is that, while they all come standard in rear-drive form, they're also available with all-wheel drive. And it's the transmission in those models that's the subject of the latest recall notice issued by the National Highway Traffic Safety Administration.
The output shaft on the eight-speed automatic transmission supplied by ZF to Chrysler for the AWD versions of the 300, Charger and Ram 1500 is apparently prone to fracture. That in the end could leave the vehicle without power and could, according to the NHTSA investigation, increase the chance of a crash. The vehicle could also roll away if even if left in Park without the handbrake applied.
That's why Chrysler is calling in 4,194 examples of those three models from the 2013 model year. Dealers will be responsible for inspecting the transmissions and, where necessary, replace the entire unit. See the full recall notice below for all the details.

Dodge Demon lightweight by SpeedKore Performance comes to SEMA

We already know that the Dodge Demon is crazy fast. We experienced that firsthand. But its more than ample amounts of built-in speed doesn't mean that owners won't be tinkering with it to make it faster. But if you don't want to add more power (or even if you do), you can always make the car lighter. That's what SpeedKore Performance Group has done, and it will bring its lightweight carbon fiber Dodge Challenger SRT Demon to the SEMA show in Las Vegas, where it will be introduced by none other than rock legend Sammy Hagar. Last year, SpeedKore brought its carbon fiber-bodied Dodge Challenger SRT Hellcat to SEMA, and now it has applied the same treatment to the 840-horsepower Demon. The body panels and spoilers will be manufactured using SpeedKore's autoclave in Grafton, Wisconsin. SpeedKore will also be one of many companies bringing a modified Ford Mustang to SEMA. A carbon-bodied Ford Shelby GT350R by SpeedKore was recently featured on "Jay Leno's Garage." Last year, Leno also drove SpeedKore's 1970 Dodge Charger Tantrum, which features a carbon fiber front end and a 1,650-horsepower Mercury Marine engine.
