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.

Is this the 2020 Dodge Charger SRT Hellcat Widebody?

Last month we told you about the heavy anticipation that Dodge will release Charger Widebody versions in SRT Hellcat and R/T Scat Pack trims for 2020. Now we have strong visual evidence to back it up. This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings. Instagram user and self-described motorsports enthusiast zl1_dre_92c captured a brief video while out driving around suburban Detroit Tuesday of what appears to be a Charger SRT Hellcat Widebody with more pronounced fenders and distinctive graphics passing him in traffic. We can see SRT spelled out on the lower passenger front door and on the rear fascia, and curiously, it appears to be sporting a Florida license plate. Mopar Insider says a source told it that's because Dodge was trying to keep the muscle car away from the usual prying eyes in Detroit and instead has been running it around its secret testing facility near Naples, Fla. The website further surmises that the model could well debut this weekend at the SoCal LX Club Spring Fest 14 in Pomona, Calif., an annual gathering of Mopar fanatics. That would explain the flashy wrap graphics and our suspicions that this isn't a test car; why else would Dodge so clearly advertise the car's SRT lineage? Although both models would get specialized suspension tuning, it's believed that the engines and outputs will remain — a 485-horsepower, 6.4-liter V8 in the R/T Scat Pack and the 6.2-liter V8 making 717 hp for the SRT Hellcat. Both will also reportedly get the same 20-by-11-inch Pirelli performance tires as are found on the Challenger Widebody. They're wrapped around five-spoke blacked-out aluminum wheels, accented with red brake calipers. It appears we'll know more about this curiosity soon.

2015 Dodge Challenger SRT Hellcat gets brace of new videos

Yesterday's big announcement focusing on the new Dodge Challenger SRT Hellcat had plenty of stuff going for it - information, pictures and the rabid enthusiasm that always accompanies such an eagerly anticipated reveal. What it was lacking, though, was a proliferation of videos of the new model.
Sure, yesterday's news came with one clip, but today, Dodge has come through with five videos. We've arranged them in what we think will be the most entertaining order, covering the powertrain, before moving on to exterior and interior design, then on to a full CGI dissection of the SRT Hellcat before capping things off with a piece on the non-supercharged Challenger SRT392.
Take a look below for all five videos, then head into Comments and let us know what you think.
