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.

2021-22 Dodge Challenger Hellcat drops manual option

The six-speed manual has been dropped from the 2022 Dodge Challenger Hellcat at least temporarily while it awaits a powertrain calibration update that will allow it to be sold again, Road & Track reports. The combination has been unavailable to order since November 2021, Stellantis said.  Dodge didn't give R&T much of an explanation regarding the combo's absence, saying only that a revised calibration that would allow the configuration to be sold is coming. When is anybody's guess. In the meantime, we're starting to wonder just how committed Stellantis is to offering its V8s to buyers who aren't opting for half-ton pickups or larger. The inline-six that is slated to replace the 5.7-liter Hemi variant in at least some applications is expected to debut soon. While the 5.7-liter Hemi has surely more than paid for itself at this point, it's likely that Stellantis is limiting availability only to its most profitable models, which help offset the CAFE costs associated with lower fleet mileage. And while Stellantis made quite a bit of noise in recent years about its customers wanting V8s, options for such have become thinner on the ground. The new Grand Cherokee is ostensibly offered with the V8 on its three top trims — Trailhawk, Overland and Summit — but only the last of those can be found anywhere in U.S. inventory with a Hemi under the hood. Trailhawk and Overland V8s simply do not exist. You don't have to take our word for it; you can look for yourself.  Related video: This content is hosted by a third party.

FCA announces the winners of its Design Sketch Battle contest

Fiat-Chrysler Automobiles (FCA) designers Ralph Gilles and Mark Trostle announced the winner of the first Design Sketch Battle on their respective Instagram accounts. The 24-hour contest invited designers and enthusiasts from all over the world to submit their "wickedest and most outrageous designs for a Ram truck." Participants flooded the company's various social media accounts with creative submissions that did not disappoint. Ralph Gilles, FCA's head of design, selected submissions sent by Paul Piliste, Rezo Lomaia, Michael Stanfel, Morten Rabiee, and Joshua Reese. The sketches he selected all put a decidedly futuristic spin on Ram's design language, and one is a tribute to the original Power Wagon introduced in 1946. They embrace the company's rugged side with oversized wheels and ground clearance measured in feet, not inches. Don't look for street-oriented, low-to-the-ground performance -— like Gilles' own Tomahawk GTR sketch from 1995 — here. We've embedded his winners below. This content is hosted by a third party.

He selected work by Bryan Johnson, Robin Mathew, Ricky Ryan Goimarac, Jon Sibal, and Sean Smith. His attention gravitated towards futuristic designs, too, but he channeled his inner hot-rodder by choosing what looks like a slammed quad-cab Ram with a front fascia and fender flares from a wide-body Challenger. His fifth pick is one we'd love to see in showrooms: it blends retro-inspired and modern styling cues in a street-oriented high-performance package. His winners are embedded below.

In the world of Lego, designers can compete for the chance to add their one-off creation to the company's catalog of current and classic cars. We don't know if FCA will give the Design Sketch Battle winners the same distinction. In the meantime, Gilles and Trostle both said they'd post more stand-out designs on Instagram over the weekend.
