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.

2019 Jeep Cherokee revealed | All-new engine, refreshing new face

When the Jeep Cherokee made a return in late 2013 as a replacement for the boxy Jeep Liberty, reactions were mixed on the crossover's styling. Sure, all the Jeep hallmarks were there — seven-slot grille, squared fenders, etc. — but something seemed different, especially with that face. Well, the course has been corrected and at this week's Detroit Auto Show, the 2019 Jeep Cherokee shows off its much more conventional and conservative styling. This is just a mid-cycle refresh, so it doesn't look all that much different than the current KL Cherokee. Jeep ditched the split lighting on the current model, pushing the driving lights and headlights back together and in a much more traditional position. Unsurprisingly, its very similar to what you'll find on the current Jeep Grand Cherokee and Jeep Compass. In addition to the new LED headlamps, the driving lights and fog lamps get a new design. The rear end, too, gets a heavy redesign. The taillamps now have LED accents, though the overall shape is generally the same. A new tailgate now houses the license plate, making the Cherokee look less bottom heavy. Along the bottom, Overland models get chrome tow hooks while Trailhawk models get the now recognizable bright red hooks. The Trailhawk also gets a resculpted front bumper for a better approach angle on the trails. Other Trailhawk goodies include skid plates, bigger fender flares, an increased ride height and 17-inch wheels with off-road tires. There are five new wheel offerings in total, including a 19-inch design for the Overland trim. In contrast to the outside, the Cherokee's interior carries over nearly unchanged. From behind the wheel, you'd be hard pressed to spot a difference between the old and new. There are some new piano-black trim pieces around the infotainment screen and matte silver trim around the air vents and steering wheel. The center console does get a slight redesign, moving the USB port and 115-volt outlet rearward to create a bit more storage space. The biggest change is in the cargo area where three extra inches of width give the Cherokee 27 cubic feet of cargo space. Underneath the hood, you'll find one of three powertrains, including a new 2.0-liter turbocharged inline-four. That engine joins the 271 horsepower 3.2-liter Pentastar V6 and the 180 horsepower 2.4-liter Tigershark inline-four. All three engines are paired with a refreshed nine-speed automatic sending power to either the front or all-four wheels.

Watch a Jeep CJ get disassembled and reassembled in minutes

Movie buffs! Remember the scene in the James Bond film 007: The Living Daylights where Timothy Dalton's character slices the floorpan off a police Lada using a laser, and when the driver hits the brakes the Lada's body simply jumps off its axles? That scene was immediately brought to mind as I watched this clip of eight Canadian mechanics disassembling a slightly modified Jeep in a matter of seconds. Having driven the Jeep to a complete stop, the technicians start unbolting it until the body lifts off the frame and the engine can be hauled away. It only took half a minute to turn the Jeep into just a chassis on wheels. As repair manuals say, refitting is the reversal of removal. Apparently the technicians have now honed their mechanical choreography to the point that the Jeep can be disassembled and reassembled in two minutes and 39 seconds; while I expect a great number of bolts having been removed beforehand and the likelihood of the Jeep falling to pieces with a sharp braking being significant, it is definitely impressive. It also reminds me of someone driving an old, dodgy car, having learned all its kinks to be able to keep it running. According to a Reddit thread, the pre-modified "Jifty Jeep" has been built (and taken apart, and rebuilt) by the School of Royal Canadian Electrical and Mechanical Engineers (RCEME) for exactly this purpose. The team travels all around Canada to practice their show, trying to shave seconds off their record. There are worse hobbies.
