Here's what it'll take to build a Jeep Grand Cherokee Hellcat

Let's get one thing straight: We want a 707-horsepower Grand Cherokee Hellcat to happen. Badly. The latest report from Motor Authority is encouraging; the bonkers SUV supposedly has a codename, Project K, and has been given the green light for production. Fingers crossed. You might be wondering why the Trackhawk isn't already a thing. Hellcat engines exist, SRT Grand Cherokees exist, so just combine the two, right? It's not quite that easy. Here, we outline what needs to happen, why it should be the quickest Hellcat vehicle out there, and why it won't come anywhere near 200 miles per hour. How To Build A Hellcat Jeep The first engineering problem is feeding the air-intensive beast that is the 6.2-liter supercharged V8. The first engineering problem is feeding the air-intensive beast that is the 6.2-liter supercharged Hellcat V8. Breathing is important on two counts: pulling in enough air for the combustion to put out 707 hp, and then cooling the various heat exchangers once the engine is up to temperature. Dodge did it with the Charger and Challenger, it can do it with the Jeep. This is one place where the Grand Cherokee's larger frontal area might be a boon, as it gives the engineers more surfaces through which to suck air. Once you generate the 707 horsepower and 650 pound-feet of torque, it has to get to the wheels somehow. Jeep's current SRT all-wheel-drive system will at least need some beefing up to handle the torque. It could require a more complete re-engineering. We at least know the ZF-supplied eight-speed auto, used in the Dodge Hellcat models, is up to the task. The Hellcat engine should fit in the Grand Cherokee, as it's about the same size as the 6.4-liter currently in SRT Jeeps, but the Hellcat is taller because of its supercharger. The hood may need to be raised or at least resculpted for clearance, as well as to address those cooling needs. Quicker Than Everything, But Not Faster 200 mph? We're skeptical, from both a physics standpoint and a legal one. A reminder of the quick/fast distinction: quick is acceleration, fast is road speed. The Jeep's all-wheel drive will help put the Hellcat engine's power to the ground in a more manageable way than the Charger and Challenger do through just the rear wheels. That means better acceleration times than the Dodges (11.0 seconds in the quarter-mile for the Charger Hellcat, 11.2 for its Challenger sibling).

NHTSA upgrading Jeep Grand Cherokee, Dodge Durango headliner fire probe

The National Highway Traffic Safety Administration investigation into headliner fires experienced by a small number of Jeep Grand Cherokee and Dodge Durango owners has been upgraded to an engineering analysis, the step before the initiation of a recall. In August last year the investigation began with 146,000 Grand Cherokees from 2012 after three complaints were received, but a report on Edmunds says it has been expanded to include 593,299 vehicles covering the 2011-2013 model years for the Jeep and the Dodge Durango, which uses the same headliner assembly, because of possibly 52 incidents of fire.
In some of those incidents drivers have reported a burning odor, smoke or open flames that were contained to the headliner or migrated to another area of the passenger compartment. The culprit has apparently been found: NHTSA blaming an electrical short in the sun visor vanity light wiring, which is routed under the headliner and held in place by three screws. Chrysler began its own probe into the issue when it was first reported and is still looking into the situation while, "fully supporting the National Highway Traffic Safety Administration's investigation."

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.
