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.

Dear Ram: 'GT' doesn't belong on a pickup

When word of the forthcoming Ram G/T models hit our inboxes on Tuesday, my first reaction was one of confusion. The notion of a "Grand Touring" package for anything with a pickup bed struck me as entirely foreign and left me feeling conflicted. Have pickup trucks really come so far that a GT-inspired model makes sense, or am I just married to an antiquated notion that has been co-opted and subsequently bled to death by the endlessly churning automotive marketing machine? One could reasonably argue that "GT" has come a long way from the days when it was closely associated with its namesake term (whether you say "Gran Turismo" or "Grand Touring" really makes no difference) and plenty of not-so-sporting automobiles have already borrowed the nomenclature to denote trims with faster-looking body kits or larger wheels. If that's the model we're choosing to acknowledge, Ram's is arguably ahead of the game. Its G/T package adds a cat-back exhaust and cold air intake (more of a performance nod than some other "GT" models enjoy), paddle shifters, a console-mounted gear lever, unique bucket seats with high bolsters and metal covers for the gas and brake pedals. If this were a package for a Dodge Charger or Challenger, it would certainly check the right boxes. Heck, the whole thing was essentially parts-binned from the TRX with an assist from Mopar's factory accessory catalog.  A Ford Mustang GT and a Mercedes-AMG GT. Note how similar they are to a half-ton truck. In my quest to decide just how out-of-touch I am, I first asked Ram whether G/T actually stands for anything. It doesn't. It was chosen simply to "signify a sporty model within the lineup." There's no apparent significance to the slash aside from being an obvious nod to Dodge's R/T (Road/Track) models, of which even the Viper was one. Even with SRT having supplanted R/T atop the Mopar performance heap, the latter still denotes models with a significant performance increase.  But that means G/T is precisely what we think it is — a trim meant to impart notions of performance, even if there's little of it to be found. It doesn't quite sit with me. The domestics have already pretty much forced us to accept the notion of both high-performance and luxury-oriented pickups, so something splitting the difference doesn't really seem that outrageous.

Cummins builds 2-millionth diesel for Ram

Ahead of a new Ram Heavy Duty that will debut sometime next year (check out the spy shots below), Chrysler and Cummins are celebrating a milestone in a 24-year partnership that has supplied the Ram pickup with diesel engines.
In its early years, the Cummins straight-six turbo diesel was rated at just 160 horsepower and 400 pound-feet of torque, and its clattering 12 valves could be heard from a mile away. Its most recent configuration still uses a straight-six layout, but displacement grew to 6.7 liters in 2007 allowing the engine to now produce up to 385 hp and a whopping 850 lb-ft of torque. While a rumored smaller Cummins engine for use in the light-duty Ram 1500 never materialized, the work-ready 6.7-liter Cummins turbo diesel accounts for 80 percent of all Ram HD sales.
Chrysler has not yet announced when and where this two-millionth engine will be on display, but you can read more about the engine and the partnership in the press release below.
