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.

Junkyard Gem: 1976 Dodge D100, United States Army Edition

Members of the United States military have been driving Dodge trucks since the Army bought its first Dodge Brothers ambulance in 1917, and plenty of third-generation D-series pickups ended up in Army service during the mid-1970s. Most of these were 3/4-ton W200s and D200s (designated as M880s), but today's Junkyard Gem is a 1/2-ton D100 CARGO PICKUP W/CAB, found in a Denver self-service wrecking yard. Eventually, the Army auctions off old vehicles, and that happened to this battered D100 Custom at some point. This truck appears to have started life with Navy gray paint, which was painted over in Army-grade olive drab. Perhaps there was some vehicle-shuffling done by the Pentagon. The most recent layer of stickers shows that this truck's final military job was for the U.S. Army Recruiting Command. Power came from the legendary Chrysler Slant-6, in this case the 225-cubic-inch version rated at 105 horsepower. Like most fleet vehicles of the last 50 or so years, it has an automatic transmission. You couldn't expect every soldier to be able to work a three-pedal truck, not even way back in 1976. The Rust Monster has taken a few bites out of this truck, enough that its resale value converged with the current price of scrap vehicles. This content is hosted by a third party.

Ranking Dodge's Charger Hellcat with the fastest sedans in the world

"This is a car that most brands would never bring to market." - Tim Kuniskis
Dodge CEO Tim Kuniskis had reason to be confident, perhaps even a bit cocky at the reveal of his brand's newest halo car, the 2015 Dodge Charger SRT Hellcat. As he said simply, it's the "quickest, fastest and most powerful sedan in the world."
