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.

Federal investigations about safety of rear-mounted gas tanks is nothing new

The National Highway Traffic Safety Administration and Chrysler are currently making waves in our daily news feeds due to a disagreement over the safety of a few million Jeep Liberty and Grand Cherokee models. Specifically, NHTSA has asked Chrysler to recall the SUVs because of the location of their fuel tanks, but you may be interested to know that requests such as this are nothing new.
Besides the two Jeep models, NHTSA has launched investigations over the years in such models as the Ford Crown Victoria (and its police-car counterpart), GM pickups built between 1972 and 1987, and rather famously the Ford Pinto.
Understanding how automakers and NHTSA have dealt with fuel-tank-safety concerns in the past may offer a better understanding of how Chrysler and the government agency will settle their current dispute. Check out the complete article from The Detroit News here.

2018 Jeep Wrangler Unlimited JL Sahara Drivers' Notes Review | Fun, multiplied

The 2018 Jeep Wrangler Unlimited JL has huge boots to fill. Its predecessor, the Wrangler JK, was one of the most important vehicles ever, truly breaking Jeep's icon into the mass market. The outgoing Wrangler — especially the four-door Unlimited model — was finally a car you could comfortably live with seven days a week. The new model improves on it in every way without sacrificing what makes Jeeps so beloved. Our loaner was a optioned-up Sahara Unlimited. If you're going for maximum on-road comfort, this is the one to get. It has quite a few options, bumping the as-tested MSRP to $52,235. Features include leather upholstery, heated seats, LED lighting, an upgraded infotainment system, blind-spot monitoring, a body-color hardtop and a Dana 44 rear axle. Editor-in-Chief Greg Migliore: The 2018 Jeep Wrangler is a step forward for this legendary off-roader, improving it in subtle ways that truly effect change. The upgrades feel cohesive and work in harmony to create the most capable and sophisticated Wrangler ever. We tested a loaded-up Unlimited Sahara, which stickered for the eye-watering tally of $52,235. Make no mistake, the Wrangler is a premium SUV. I've always said that if I were to own a Wrangler I'd go for basic trim, but after driving this almost dressy Jeep, I'm not so sure. It's expensive — but it's really nice. The changes for 2018 involve powertrain, design and features. You can read about them here. The styling is what I kept noticing. The changes are subtle, but after looking at it — I'd often stare at it while sipping a cup of coffee last weekend — it really elevates the Wrangler with a more modern look. In Unlimited Sahara trim, with the elegant LED lights, 18-inch polished gray wheels and brilliant white exterior paint, it reminded me more than a bit of the Mercedes G-Class. The greenhouse, which has slightly new and larger window shapes and a steeper windshield angle, also evokes the G-Class, to my eye. This probably wasn't Jeep's intent, but it looks sharp. Speaking of subtle changes, I'd compare the Wrangler's styling changes to the alterations to the Detroit Tigers' uniforms, also from 2017 to 2018. The interior is a solid upgrade from the JK. The digital instruments, the Sahara trim's smart use of leather and stitching, and FCA's clever Uconnect all made my experience in the Wrangler pretty comfy. Love the old war Jeep on the shift knob. The driving experience does feel more comfortable to me compared to the JK.
