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.

Researchers who busted VW cheating say FCA's diesels dirty, too

The Wall Street Journal today reported on an upcoming report from West Virginia University's Center for Alternative Fuels Engines and Emissions, which is the same lab that investigated Volkswagen emissions cheating. The report, which will be released in a matter of weeks, alleges that 2014 and 2015 model year Jeep and Ram vehicles with diesel engines emit excess pollution. But it does not specify whether the company used defeat devices. Since the report discusses Jeep Grand Cherokees, and that engine is also available in the Ram 1500, it's safe to assume that one of the implicated engines is the EcoDiesel V6, a unit actually produced by VM Motori. It's unclear whether the report covers any of the Cummins engines used in heavier-duty Ram pickups. This report comes on the heels of a federal investigation into FCA's diesel vehicles. That investigation focused on the EcoDiesel engine used in 2014-2016 vehicles. The feds were seeking a fine of up to $4.6 billion. The EPA and the State of California also previously accused FCA of using a defeat device on the same vehicles back in January. FCA, for its part, alleges that the WVU study might have been commissioned by people interested in suing the company, and disputes the testing methodology, according to the WSJ. We've reached out to WVU to confirm which engines are implicated in its study and will update this post when we have more to share. Related Video: This content is hosted by a third party.

Dodge Durango SRT vs. Jeep Grand Cherokee SRT | Which should you buy?

Choice is a good thing. And when it comes to high-performance sport utility vehicles, there are more choices today than ever before to tantalize buyers into showrooms. And why not? Americans love SUVs, and, while there's a stronger push to go green now than ever before in the history of internal combustion, there's still a large contingent of buyers who firmly believe in choosing the biggest, baddest, most powerful powerplant. For those buyers, the Dodge Durango SRT and Jeep Grand Cherokee SRT are two of the most potent options. But which one should you buy? They both deliver 475 horsepower and 470 pound-feet of torque to all four wheels through an eight-speed automatic transmission. They both do 0-60 in around 4.4 seconds, and both boast top speed numbers that will handily land you in jail if written on a speeding ticket. Choosing between the two, then, is a bit more nuanced than which is faster. That said, the Jeep is probably a bit quicker at the track than the Dodge. We'd wager than the Grand Cherokee SRT's 5,104-pound curb weight (versus 5,510 for the Durango SRT) and 114.8-inch wheelbase (versus 119.8) will pay small dividends in acceleration, cornering, and braking performance. So, if that's the only category by which you believe these SRT-fettled SUVs should be judged, choose the Jeep. View 17 Photos But let's get real here for a moment. As much fun as it is to wrangle a brutish ute 'round a racetrack – and trust us when we tell you it's a blast – the number of hi-po SUV owners who will ever show up at Bondurant in an SRT-badged 4x4 is probably in the single digits. So, when evaluating which of the two Hemi-powered vehicles is right for you, ultimate lap times are probably of little concern. If you're choosing between these two overpowered players, practicality is probably just as important as performance. And in that category, the Durango SRT comes out on top. For starters, the Dodge is a three-row SUV with six seats, whereas the Jeep is a two-row, five-passenger platform. Fold down the rear bench and there's 84.5 cubic feet of cargo area in the Durango, versus 68.7 in the Grand Cherokee. And if you tow, the Durango SRT's 8,600-pound max rating handily bests that of the Grand Cherokee SRT's 7,200-pound capacity. Ask yourself what's most important: performance or practicality. And then consider the price. The Dodge is nearly $4,000 less expensive than the Jeep.
