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.

The 2018 Dodge Demon sounds like nothing else on the road

The Dodge Demon seems to have a torque problem, if making too much to easily contain can be considered a problem. In order to keep all that twist under control, the Demon has a new torque reserve launch system that works all sorts of engineering black magic to build boost without overloading the rear tires and brakes. That system, combined with the sticky Nittos and the fancy new suspension, should lead to some pretty spectacular 60-foot and 1/4-mile times. The way the system works is relatively straightforward. A bypass valve on the supercharger closes, "prefilling" the blower. In order to balance revs and torque, the computer can adjust fuel flow and spark on individual cylinders. The torque reserve kicks in when Launch Mode is initiated and the engine is turning at least 1,000 rpm. The goal is to reach peak boost quicker while efficiently putting down power. The side effect is a distinct exhaust note, which Dodge admits may make it seem like the Demon is broken. That seems to be the root of the "If you know, you know" tagline that the automaker has been using since the first teaser. Those interested can even download a ringtone, which might make it seem like you have a blown-out speaker on your phone. You can get a brief taste in the latest teaser video. In addition to the new info on the Launch Mode, Dodge released a couple of new teaser images. We briefly glimpsed one of these last week. It's a shot of the Demon's performance pages. The number 757 has appeared before, and all the talk of torque leads us to conclude that this is the Demon's torque output. The number 815 was seen in a separate teaser (shown below), which we feel may be the horsepower rating. If those numbers are correct, that would mean an increase of 108 horsepower and 107 lb-ft of torque, totally reasonable numbers given all the Demon's modifications. The license plate photo is another equation or code. This one, 3.9+221=405, is just as cryptic as the others.

Tempted by the Demon, dealers find way to thwart Dodge, jack up prices

It's the eternal story of short supply, big demand - and car dealers eager to exploit that dynamic, especially when it involves a hot car. A few weeks ago, when Dodge announced that it devised a way to attempt to prevent price-gouging on those 840-horsepower 2018 Dodge Demons, you just knew the dealers would dream up some devilish end-run. And sure enough, despite the manufacturer's best intentions, Demon order slots are being offered with five-figure markups. Here's how things were supposed to work: With a run of just 3,000 cars, Dodge knew it had to do something to address dealer greed, so it announced an allocation system: Cars purchased at or below the $86,090 MSRP would be the first orders filled and delivered. If a dealer sells an allocated Demon for more than sticker, that car goes to the end of the line for production and delivery. Dodge also ensured dealers wouldn't stockpile or hoard Demons by limiting the number of orders a dealer can submit and allocating cars to dealers based on how many Challenger and Charger Hellcats the dealer has sold. But Automotive News reports that some dealers are using intermediaries to auction off their Demon allocations on eBay. Three sellers last week said they were representing dealers in South Carolina, Tennessee and Louisiana, and auctioning off the right to buy a car in one of the priority spots at MSRP. The minimum bid for the right to buy the car at sticker? From $10,000-25,000. And previous transactions on eBay might have run as high as $75,000. So early buyers are definitely paying an upcharge - but it's a thing apart from the bottom line on the order form, where it appears they are paying MSRP. In other words, a scheme that violates the spirit of what FCA tried to do. A source at FCA told Automotive News the automaker was monitoring the practice but could do little to stop it. And the report quoted a Hellcat owner who said his dealership was ignoring Dodge's strictures altogether and offered him a Demon at MSRP plus $60K. But take heart. Not all car dealers are cynically opportunistic - or rather, some see an opportunity for doing good, not making buck. Automotive News says Bill Marsh Chrysler in Traverse City, Mich., plans to sell its single allocated Demon for $1 under MSRP - and is auctioning off the right to buy it, with the dealership's existing customers eligible to bid. The auction's proceeds will benefit four Traverse City charities.
