NHTSA investigating Ram 1500 models for rear differential failure

The National Highway Traffic Safety Administration is investigating Fiat Chrysler Automobiles and its Ram brand following a number of reports regarding the 2005 Dodge Ram 1500 pickup. According to 15 consumer complaints, the trucks' rear differential locked up while in other cases, the driveshaft separated at its connection to the diff.
Nearly half of the reports claim the truck was traveling at or above 50 miles per hour, while two consumers reported that the diff lockup/driveshaft separation sent their pickups into a spin. Most troubling, though, is that consumers reported little to no sound indicating there was a problem with their truck.
We reached out to Ram for additional information, such as how many vehicles may be affected or what equipment might be fitted that could cause the issue. Unfortunately, the company wasn't willing to elaborate on specifics.

It ain't easy keeping a Hellcat steady at 170 mph on ice

The Dodge Challenger SRT Hellcat you see hit the ice at Arsunda Speed Weekend in Sweden, over two hours north of Stockholm. It's said to be bone stock, save for the studded tires that help it grip on ice. But it apparently takes more than some steel studs and a lead foot to keep it pointed the right way. Just look at how much driver Alx Danielsson has to saw at the wheel to keep the Hellcat from veering off course. Fortunately he seems to have the chops to do so, being not only a native of Sweden (and therefor imbued from birth with otherworldly abilities to drive on ice) but also having won the highly competitive Formula Renault 3.5 Series championship back in 2006. In the end Danielsson hit a top speed in excess of 170 miles per hour, touted as some sort of record, however unofficial (and specific to Dodge Challengers). That's a fair bit shy of the 205 mph that Bentley achieved in the Continental Supersports, but while that model had slightly less power than the Hellcat, it did have the benefit of all-wheel drive – something that could make all the difference in these kinds of slippery conditions.

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.
