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.

Ram 1500 mule caught sporting Mega Cab configuration

Our intrepid spy photographers have once again captured an unusual test mule out in the wild. This time we have a Ram 1500 that looks a little lengthy in the middle. We're pretty certain this is a 1500 and not a heavy duty model judging from the grille and hood. That said, FCA clearly went to great lengths to hide the cab. It's still clear that the rear section is longer than your typical quad cab, leading us to believe that the Mega Cab option will return to the 1500 line. Other interesting details are the covered tailgate and the Chrysler steering wheel in the interior. We're not entirely sure why it's covered up, as it doesn't appear to have a different function, but there could be some styling tweaks for a new trim level. The one part we can see is the tailgate handle, which may reveal some updated camera abilities as the normal location shows a differently shaped camera lens. There are also two small spots that could be cameras, but it's tough to say for sure. Will we see 360-degree imaging on the next Ram? The steering wheel is an unusual inclusion as well. Our photographer suggests that it could be necessary for using the latest UConnect infotainment system. Other than the wheel though, the interior looks identical to the current model. This updated cab option also leaves us wondering about the future of the Ram line. We have documentation that shows FCA plans to launch some type of refreshed Ram for the 2018 model year. So it's possible we're looking at an early test mule for that updated model, and the new cab option could be launched at the same time. In many ways, this Ram brings up more questions than answers.

FCA goes natural with CNG fleet

FCA Transport, the fleet of tractor trailers owned by FCA US that hauls parts from suppliers and to assembly plants, is going green. By converting its 179 trucks from diesel to compressed natural gas, CO2 emissions will drop by 16,000 tons per year based on the cumulative 16 million miles the fleet covers annually. That is roughly equivalent to the yearly energy use of 1,500 homes, the same as not burning more than 17 million pounds of coal. FCA says rolling out the largest CNG-powered truck fleet in Michigan took two years to execute and a $40-million investment, including $5 million to build the largest private CNG station on the continent. It also required the assistance of Cummins, Allison Transmission, and Agility Fuel Systems. There is an upside for FCA Transport in all of this: the company estimates fuel savings of 35 percent from not having to buy 2.6 million gallons of diesel every year. It's probably no coincidence that this announcement comes as world leaders tackle the same problems at the Paris Climate Change Conference. The press release below has more. FCA US Launches Largest Private Fleet of Natural Gas-Powered Semitrucks in the State of Michigan- Company announces $40 million investment in Detroit to convert 179 parts-hauling trucks to compressed natural gas (CNG)- Investment includes facility and infrastructure upgrades and the installation of the largest private CNG fueling station in North America- Fleet's transition to CNG will reduce CO2 emissions by more than 16,000 tons per yearDecember 4, 2015 , Detroit - FCA US LLC announced today that it has invested $40 million in FCA Transport, the FCA US-owned truck fleet, to convert its 179 Detroit-based parts-haulers to run on compressed natural gas (CNG) rather than traditional diesel. The move gives FCA the largest private fleet of CNG-powered heavy-duty vehicles in the state of Michigan."Our transition to CNG reflects the way FCA US attempts to balance our search for profitability with social responsibility and community development, including environmental stewardship," said Steve Beahm, Senior Vice President – Supply Chain Management, FCA – North America. "This project was a win-win-win – it offered a solid business case, clear environmental benefits and an opportunity to invest in our Detroit facility and workforce."FCA Transport, built in 1965, is located on Lynch Road in Detroit, just across from the Detroit City Airport.
