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.

Chrysler recalling nearly 141k vehicles over electrical woes

Software glitches that randomly illuminate warning lights and cause instrument cluster blackouts are forcing Chrysler to recall 140,800 vehicles, The Detroit News reports. The automaker is recalling 132,000 2014 Jeep Grand Cherokees, 91,559 of which are in the US. In addition to the Jeep recalls, Chrysler is adding 10,800 2014 Ram 1500, 2500 and 3500 trucks to the list for similar problems.
Chrysler reportedly says, "Both events occurred infrequently and appeared to resolve themselves by tuning the vehicle's ignition off and then on."
Engineers discovered a problem with the anti-lock-braking system software that causes the instrument cluster display of the Grand Cherokee to illuminate warning lights and black out - even its ABS and electronic stability control systems are affected. To fix the Jeeps, Chrysler will update the vehicle's software.

Trying the new Compass and other Jeeps on for size

If any brand has license to sell several like-sized SUVs, it's Jeep, which invented the concept in the first place. Yet, with the Cherokee, Renegade, and the redesigned 2017 Jeep Compass revealed at the LA Auto Show, just how like-sized is this trio of compact SUVs? Well, as it turns out, that answer is more complicated than just looking at various spreadsheets of specifications. After the cover was pulled off the new Compass, I managed to explore each back-to-back-to-back to see how their back seats and cargo areas compare. Perhaps obviously, the Renegade is the smallest of the trio no matter how you look it. Well, it actually has the most headroom, but rear legroom is cramped (a 6-footer can't sit behind another 6-footer) and it's quite obvious the cargo area is about nine cubic feet smaller with the rear seats raised. However, the Cherokee and Compass are surprisingly similar both on paper and in person – and even more surprisingly, the newer, smaller-on-the-outside Compass is actually a bit more spacious despite being nine inches shorter in overall length. View 14 Photos When seated in back, my knees were just touching the driver seat when it was motored most of the way back to accommodate my 6-foot-3 frame. However, the Cherokee's slightly chunkier seatback meant the Compass actually had a bit more rear legroom. I then set the passenger seat to a more average distance and again, the Compass had a slight advantage. The Cherokee did have a bit more under-thigh support, however, which indicates the seat is mounted a bit higher. But that creates a problem, as headroom is more significantly affected when the panoramic sunroof is specified. In the Cherokee, my head was into the sunroof cavity and resting against its rigid surround. In the Compass, there was just enough clearance. It should be a difference, both in terms of headroom and perceived roominess that those of average height should notice. As for their cargo areas, the Compass' is larger and more useable. With the rear seats raised, it has 27.2 cubic feet versus the Cherokee's 24.6. You can scoot its sliding seat forward to nearly equal the Compass, but of course doing so reduces its rear legroom. The main reason is width. The Cherokee is noticeably narrow and it gets worse when equipped with the optional subwoofer. In terms of maximum cargo volume with the rear seats lowered, the Compass has 59.8 cubic feet to the Cherokee's 54.9.
