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.

A look at the Dodge Demon's drag settings, modes, and go-fast tech

In the same video that gave us a peek at the 2018 Dodge Challenger SRT Demon's performance stats, there's a serious dump of info on the tech and tools that will likely help this muscle coupe slaughter drag strips. Dodge has outlined a few of them for us and we're using the power of inference to figure out the rest. Here's what we've gathered. A lot of these hints come from the Demon's version of Performance Pages, the infotainment screens that show what SRT models are doing and let the driver change the powertrain and chassis setup. There are a lot of Demon-only features, including line lock, a quick cooldown mode for the supercharged engine, and data recording. And of course there are pages to show a digital time slip with acceleration and braking figures, a g-load plot, and lots of gauges to track temps and levels. The engine output is shown in the video on a special Dyno page. It tracks horsepower and torque over time on the upper graph, and engine rpm and shift points on the lower graph. And we think it's still hiding something. This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings. Any good drag car has a line lock, allowing the driver to lock the front brakes and leave the rears free to do a nice tire-warming (or tire-shredding, depending on length) burnout. Ford has it on the Mustang, Chevy puts it on the ZL1, and now Dodge is adding it to the Demon. It should help get the giant Nitto tires up to temp for a drag run. And once the tires are warm, there's launch control, just like on the SRT Hellcat, with selectable rpm to dial things in for the conditions. The Demon also has a shift light in the cluster, and the driver can set a shift point individually for each gear. After each drag run, you can activate Quick Cooldown, which Dodge says uses the first production application of After-Run Chiller – it runs the cooling fan and intercooler coolant pump with the engine off until the coolant reaches its target temp. It's shown in one of the slides above. The checklist on the left side of that page suggests it requires a set of conditions be met to work: engine off, hood open, and sufficient battery level. This further reinforces our theory that the supercharger is going to make big boost, beyond the Hellcat's 11.6 psi. And while you're waiting for the supercharger to cool off for another run, you can review the performance data the car records.

Camaro SS, Hellcat Widebody, and an Airstream camper | Autoblog Podcast #545

On this week's Autoblog Podcast, Editor-in-Chief Greg Migliore is joined by Green Editor John Beltz Snyder and Senior Editor Alex Kierstein. We talk about a lot of American stuff, including the Chevy Camaro SS 1LE and the new Blazer, Dodge Challenger Hellcat Widebody, Ford's new train station and a diesel F-150 towing an Airstream trailer, as well as some Tesla pickup news. Somehow the Kia Stinger also made its way into this red, white and blue episode (because it's great, and it's our new long-termer). This week, we try something a little different in the "Spend My Money" segment. Autoblog Podcast #545 Your browser does not support the audio element.
