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.

Question of the Day: Most heinous act of badge engineering?

Badge engineering, in which one company slaps its emblems on another company's product and sells it, has a long history in the automotive industry. When Sears wanted to sell cars, a deal was made with Kaiser-Frazer and the Sears Allstate was born. Iranians wanted new cars in the 1960s, and the Rootes Group was happy to offer Hillman Hunters for sale as Iran Khodro Paykans. Sometimes, though, certain badge-engineered vehicles made sense only in the 26th hour of negotiations between companies. The Suzuki Equator, say, which was a puzzling rebadge job of the Nissan Frontier. How did that happen? My personal favorite what-the-heck-were-they-thinking example of badge engineering is the 1971-1973 Plymouth Cricket. Chrysler Europe, through its ownership of the Rootes Group, was able to ship over Hillman Avanger subcompacts for sale in the US market. This would have made sense... if Chrysler hadn't already been selling rebadged Mitsubishi Colt Galants (as Dodge Colts) and Simca 1100s as (Simca 1204s) in its American showrooms. Few bought the Cricket, despite its cheery ad campaign. So, what's the badge-engineered car you find most confounding?

2018 Dodge Challenger SRT Demon | First Run at Lucas Oil Raceway

We drove the Dodge 2018 Dodge Challenger SRT Demon this week. Not very far, mind you, but fast. We can't tell you all about it just yet, but we can show you what it looks and sounds like to launch it down the drag strip at Lucas Oil Raceway in Indianapolis. Thanks for watching, and come back on Wednesday, July 19, to read all about our experience behind the wheel of the Dodge Demon.
