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.

Dodge revives Challenger T/A and Charger Daytona trims for 2017

Dodge is reviving the Challenger's T/A trim and the Charger's Daytona line for 2017. Introduced on iconic Woodward Avenue just days before the annual Woodward Dream Cruise kicks off, the new variants promise more performance hardware and sportier aesthetics. We'll start with the two-door. The Challenger T/A, available with either the R/T trim's 5.7-liter V8 or the fire-breathing 6.4-liter Hemi V8, is inspired by the Challenger T/As of old. That means a less restrictive, 2.75-inch active exhaust system and a conical Mopar air filter. But there's no clear bump in output – Dodge still lists the base 5.7-liter at 375 horsepower and the 6.4-liter model at 485 hp. But hey, they're going to look cooler. Unlike the Challenger Hellcat, which should have it as standard, Dodge is including a Satin Black hood on every Challenger T/A. In fact, Satin Black is a recurring theme on this Challenger's front fascia, roof, rear decklid, and T/A bodyside stripes. And yes, the 20-inch Mopar wheels are black, too – they're also an inch wider than normal. Dodge is offering the T/A in three different trims. The base T/A has everything we described above, while the T/A Plus adds some comfort features like heated and vented Nappa leather seats, an 8.4-inch UConnect system with Apple CarPlay/Android Auto, a six-speaker stereo, and a shortcut button for the Dodge Performance Pages. The T/A 392, meanwhile, adds the 6.4-liter V8, even wider wheels, and Brembo six-pot calipers. If you prefer smoking tires with four doors, there's the new Charger Daytona. No, there's not an enormous wing on the back. But Dodge added the same kind of engine/exhaust upgrades found on the T/A while upping the top speed from 135 to 150 miles per hour. Satin Black features prominently again, with hood and rear fender graphics. The roof is also black. Unlike the Challenger, Dodge is only offering two different versions of the Daytona – the 5.7-liter base model and the 6.4-liter version, called the Daytona 392. Prices for the Challenger T/A start at $38,485, including a $1,095-destination charge, while the T/A Plus adds $2,750. Adding the 392 means shelling out $45,090. For the Daytona, you'll need a check for $40,985 for the 5.7-liter or $46,090 for the 6.4-liter. Orders for the Charger Daytona open in September, while the T/A is a month later. Related Video:

Stellantis invests more than $100 million in California lithium project

Stellantis said it would invest more than $100 million in California's Controlled Thermal Resources, its latest bet on the direct lithium extraction (DLE) sector amid the global hunt for new sources of the electric vehicle battery metal. The investment by the Chrysler and Jeep parent announced on Thursday comes as the green energy transition and U.S. Inflation Reduction Act have fueled concerns that supplies of lithium and other materials may fall short of strong demand forecasts. DLE technologies vary, but each aims to mechanically filter lithium from salty brine deposits and thus avoid the need for open pit mines or large evaporation ponds, the two most common but environmentally challenging ways to extract the battery metal. Stellantis, which has said half of its fleet will be electric by 2030, also agreed to nearly triple the amount of lithium it will buy from Controlled Thermal, boosting a previous order to 65,000 metric tons annually for at least 10 years, starting in 2027. "This is a significant investment and goes a long way toward developing this key project," Controlled Thermal CEO Rod Colwell said in an interview. The company plans to spend more than $1 billion to separate lithium from superhot geothermal brines extracted from beneath California's Salton Sea after flashing steam off those brines to spin turbines that will produce electricity starting next year. That renewable power is expected to cut the amount of carbon emitted during lithium production. Rival Berkshire Hathaway has struggled to produce lithium from the same area given large concentrations of silica in the brine that can form glass when cooled, clogging pipes. Colwell said a $65 million facility recently installed by Controlled Thermal can remove that silica and other unwanted metals. DLE equipment licensed from Koch Industries would then remove the lithium. "We're very happy with the equipment," he said. "We're going to deliver. There's just no doubt about it." Stellantis CEO Carlos Tavares called the Controlled Thermal partnership "an important step in our care for our customers and our planet as we work to provide clean, safe and affordable mobility." Both companies declined to provide the specific investment amount. Controlled Thermal aims to obtain final permits by October and start construction of a commercial lithium plant soon thereafter, Colwell said. Goldman Sachs is leading the search for additional debt and equity financing, he added.
