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.

Dodge Durango Hellcat teased in 'Fast and Furious' spot is real, headed to New York

The Durango Hellcat teased in a Dodge commercial appears to be the real deal, according to a report that surfaced Monday afternoon, and we could see it as soon as the New York International Auto Show in April. The horsepower Gods are smiling upon us.  Motor Authority says that a Dodge insider was able to confirm the existence of a Durango Hellcat, and suggested it will make its public debut at the New York show this spring. "Hellcat all the things" has become a bit of a meme, and it appears Dodge is either in on the joke, non-ironically committed to the concept, or maybe a little bit of both. A commercial FCA debuted to coincide with the release of the trailer of the latest "Fast and Furious" film gave us our first brief glimpse the new supercharged Durango SUV. Credit for the original find goes to the fine (and eagle-eyed) folks at Road & Track, who spotted the fender badge at approximately the 17-second mark in the embedded commercial. The tease left little to the imagination. The badge is shown prominently on the fender of the mystery vehicle, which isn't much of a mystery at all. It's a Dodge and it's not a Charger or Challenger; no need to overthink it.  Immediately after, the camera cuts to what is obviously a Durango silhouette, but we can't see a whole lot in the glare of its headlights.  It also makes sense from a product cycle perspective, as the Durango is well past the point where it has received its AARP card and we're not necessarily expecting a replacement. The three-row slot in FCA's lineup may go exclusively to Jeep once all is said and done.  We know (or have heard rumors) that other variants of the family SUV are in the pipeline, making it clear that FCA plans to milk the aging three-row for all it's worth. The Jeep Grand Cherokee, which rides on the same fundamental platform but with a shortened wheelbase, has already gotten the Hellcat treatment in the Trackhawk, so porting this engine over for three-row duty should be a snap.  More importantly, a mild facelift may accompany other updates to the Durango, which would conveniently explain why Dodge obscured the Durango's front end in the teaser.  If there's any downside to this, it's that FCA is going to run out of vehicles eventually. With the Ram Rebel TRX well underway and now this, there just aren't many vehicles left in FCA's various brand lineups that can physically accommodate a supercharged, 6.2-liter V8.  Hopefully they have Sawzalls.
