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.

Is a Jeep Renegade Hybrid coming soon?

We've known that Jeep is working on an updated Renegade. We've seen prototypes with updated front and rear fascias and with updated interiors. But it seems that the next Renegade will have more than just cosmetic updates. One of our spy photographers caught Jeep testing a Renegade Trailhawk that looks like a normal current one, but it has an electric shock warning sign in the window. Can we therefore assume it'll be a Jeep Renegade Hybrid? This sign seems to indicate that the Renegade will offer some sort of electrified powertrain. And its use on a lifted, off-road oriented Renegade Trailhawk seems to indicate that it'll be available throughout the trim level lineup. The question is, will it really be a hybrid or something like the Wrangler four-cylinder that features a 48-volt electrical system and a starter/generator for mild electrical assistance? This system is becoming more and more common as a way for car companies to eke out a few more mpg as well as adding some performance gains. Then again, we never saw this sign in any prototype Wranglers, so it could be possible this Renegade is using a more traditional hybrid system like you would find in a Prius or Ioniq. FCA certainly has experience with full hybrids, as evidenced by the Pacifica PHEV. The Wrangler will be getting a PHEV iteration, too. We probably don't have long to find out what sort of electrification the Renegade will receive. The visually updated prototypes we've seen aren't radically changed, so it likely won't take long to finish testing and release them. We're expecting to see the little SUV revealed by the end of the year, and probably on lots early in 2019. Related Video: This content is hosted by a third party.

Chrysler defies NHTSA, says it won't recall 2.7M Jeep Grand Cherokee, Liberty models

Facing a possible recall totaling around 2.7 million of its most popular SUVs, Chrysler remains insistent that the 1993-2004 Jeep Grand Cherokee and 2002-2007 Jeep Liberty are safe vehicles. This comes on the heels of a recall request from the National Highway Traffic Safety Administration for these two models due to fuel tanks mounted behind the rear axle, which could possibly be ruptured during severe rear-end collisions, leading to an increased risk of fire. In response to the allegations, Chrysler says that it does not agree with NHTSA nor does it plan on recalling either vehicle.
Chrysler said both SUVs "met and exceeded" the requirements for fuel-system integrity, and cooperated fully with NHTSA since the investigation was opened in 2010. While 15 deaths and 46 injuries have been reported from fires caused by rear-end collisions on these models, Chrysler is claiming that the vast majority of incidents cited by NHTSA were "high-energy crashes," including one where a stopped Grand Cherokee was rear-ended by a tractor trailer going 65 miles per hour.
The automaker wraps up by saying "NHTSA seems to be holding Chrysler Group to a new standard for fuel tank integrity that does not exist now and did not exist when the Jeep vehicles were manufactured." Scroll down for Chrysler's official response to NHTSA, but we're pretty sure this isn't the last we've heard on this issue.
