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.

Driving the Jeep J6, Shakedown Challenger and other Mopar concepts

Mopar has been a one-stop-shop for factory-backed performance modifications and accessories on FCA products for a long time now. You want a 707-horsepower engine for your old Plymouth Belvedere? Mopar has you covered with the Hellcrate. Maybe you want a lift and off-roading lights on that newly-bought Wrangler? Mopar can accommodate those wants (or needs, we don’t judge) as well. We get to see some of the companyÂ’s weirdest creations every now and then, but rarely do we get the opportunity to drive the FCA Mopar concepts. ThatÂ’s what made this past Woodward Dream Cruise so special: We got to rip some of MoparÂ’s finest and most recent creations up and down Woodward Avenue. Everything from a 1971 Challenger restomod to the brand-new Easter Jeep Safari J6 concept was in attendance, so letÂ’s get right to it. Mopar Woodward View 6 Photos 1967 Plymouth Hellvedere This car is near the pinnacle of what you can do with off-the-shelf Mopar purchases. It was only a humble 1967 Plymouth Belvedere before Mopar dropped the 707-horsepower supercharged V8 from the Hellcat into the engine bay. Sound ridiculous? Yeah, it is. Other parts of it are new as well, including the disc brakes. Good call. However, Mopar didnÂ’t remove the classic car charm from the entire driving experience. The steering, for example, is surely as slow and inaccurate as it was back in 1967. That doesnÂ’t help matters when youÂ’re trying to put 707 horsepower to the pavement with less-than-ideal rear rubber. Floor it in damn near any gear of the Tremec six-speed, and the front end rises straight up as the rear kicks sideways with the force of many mules. There are no electronics such as traction control or stability control to step in and wrangle the car into submission. But hey, who wants them, anyway? The question remains: Should you buy a Hellcrate engine for your classic? If money were no object, the easy answer is yes. Have at it so long as you love smoky burnouts and excessive amounts of horsepower. Just make sure you know how to deal with that much power before you stick your right foot in it.   Dodge Challenger Shakedown View 15 Photos 2016 Dodge Shakedown Challenger Concept WeÂ’re going downhill in horsepower with this restomod, but the drivability and ease of driving goes way up. Dodge showed this “Shakedown” concept at SEMA awhile back, and as with most concept cars, getting a chance behind the wheel is a special opportunity.
