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.

2017 Jeep Cherokee vs. all-new Compass

If Fiat Chrysler Automobiles (FCA) can be described as on a roll, it's not by virtue of Fiat or Chrysler. The Fiat brand continues to struggle, with a restricted lineup and fragmented dealer network. The Chrysler brand is reduced to two models: an all-new Pacifica minivan and a 4-door sedan – the 300 – desperately in need of a revamp. And while Dodge is building interest via high-performance, its platforms are dated. The only real excitement is within the Ram and Jeep ranks, where global growth is fueled by cheap gas and a wealth of new intros. The newest Jeep is the Compass, and while classified as a compact, its size, interior room, and powertrain overlap nicely (or confusingly) with its midsize sibling, the Cherokee. And given their close proximity in price – the Trailhawk Compass starts in the high $20,000s while the Cherokee begins in the low $30,000s – they both could easily appear on a buyer's short list. Jeep Cherokee Trailhawk: This is an interesting crossover entry on many levels. You could begin with its polarizing sheetmetal. If, as a Jeep loyalist in 2014, you had expected the two-box profile of its wildly successful predecessor, you'd have missed the mark by an off-road mile. With a front-wheel-drive/all-wheel-drive platform housing a transversely mounted four or (optional) V6, you could store a small refrigerator in the new Cherokee's front overhang. And the previous Cherokee's slab sides and expansive greenhouse have morphed into aggressively sculpted sheetmetal and essentially no greenhouse. Yet we've grown to like it, but only as a jacked-up, big-wheeled Trailhawk. If considering the more street-oriented, front-wheel drive Cherokees, you'd do well to cross-shop. Inside, the Cherokee Trailhawk impresses. Its design and details hit above the competition, and the Cherokee won Ward's Autos 'best interior' at the time of its introduction. The Ward's team gave a shout-out to an interior "roomy, comfortable, and boldly styled with highly sculpted shapes and contrasting colors. Fold-flat rear seats add lots of utility and the Uconnect system is the best in the business." Our take is similar, and while in its fourth model year you could expect a refresh soon (make that very soon), there's little wrong with this introductory baseline. With roughly 25 cubic feet of space behind the second-row seat, you won't be blown away by the Cherokee's cargo capacity.

Chrysler registers Trackhawk trademark

There may not be many ways to forecast what an automaker is planning for the future, but there are some. Trademark applications are one of them, and Chrysler has just applied with the US Patent and Trademark Office to protect the name "Trackhawk." The question is, what's it planning on using it for? We don't know for sure, but we can put together an educated guess or two. And one guess is that Jeep will use the name to replace the letters SRT on the performance version of the Grand Cherokee.
How do we figure, you ask? From a number of developments. For starters, the SRT division has been reintegrated into the Dodge brand. Those letters currently appear on only two vehicles from outside the Dodge lineup: one is the Grand Cherokee SRT, and the other is the Chrysler 300 SRT. We've heard ruminations (however unconfirmed) that the latter could be either discontinued or possibly relabeled, and if the same proves true of the GC, the Trackhawk name could serve as a on-road performance counterpart to the Trailhawk label applied to off-road versions of models like the Cherokee and Renegade.
Logical it may be, but it's hardly a foregone conclusion. The Trackhawk name could just as easily be used for a new concept (like the Trailhawk name was in 2007), for another kind of trim level or for something else entirely. In fact we don't even know for sure it'll be used by the Jeep brand specifically, or used at all for that matter. Automakers have been known, after all, to register names they don't end up using.
