Here's how I averaged 31.5 mpg in a Ram HFE EcoDiesel

Few things could be more American than a bright red Ram pickup parked in front of Mount Rushmore. To get there and back on a single tank of fuel from the nearest major city, however, requires a collaboration of international proportions. This particular Ram is a 1500 HFE EcoDiesel, festooned with badges indicating the presence of an Italian turbodiesel V6 mated to a German eight-speed automatic. Some Rams are even built in Mexico, but this one only boasted a 27 percent Mexican parts content. A rather global truck, this one. It is the sum of its parts, but those bits and pieces were curated by a team of engineers in Michigan. At the risk of hipstering its history, the Ram HFE (High Fuel Efficiency) package was truly custom-tailored for one purpose: Achieving an EPA-rated 29 mpg on the highway, which is 1 mpg better than a standard Ram 1500 EcoDiesel. It did just that. No, it did better than that, but more on that in a minute. The Ram has stuck with its "son of big rig" styling for nearly 25 years; opting for the EcoDiesel V6 means you can fill up next to Peterbilts. My goal was to bypass truck stops entirely. I left Denver early in the morning and aimed to enjoy lunch with Washington, Jefferson, Roosevelt, and Lincoln looking over my shoulder before heading home for dinner. Mt. Rushmore is about 370 miles away from the northernmost truck stop within Denver, where I filled the Ram HFE's tank and headed northbound on Interstate 25 toward Wyoming and a series of smaller highways that roughly follow an old stagecoach route from Cheyenne to what is now Mt. Rushmore in South Dakota. The Ram was such a fuel miser that I could have driven an extra 50 miles each way and still avoided the pumps. It's beautifully stark country: the kind of desolate place where the FM radio does a lot of seeking; that's all the audio I had on board because the Ram HFE is decidedly lacking in comfort and convenience features. To get to an EPA-estimated 29 mpg highway figure, Ram engineers had to goals: To strip weight and improve aerodynamics. In the wind tunnel, the medium-size 4x2 Quad Cab with 20-inch wheels and the Ram Express trim level's one-piece front bumper proved the most aerodynamic configuration of the many flavors of Ram available. Interestingly, testing revealed that adding full-length tubular side steps and a tri-fold tonneau cover normally offered in the Mopar accessories catalog aid aerodynamics.

Chrysler recalling 382k Ram HD diesel pickups, 184k SUVs

Between GM's ignition switches and Takata's airbags, it's been a big year for recalls, but they keep rolling in. The latest comes from Chrysler, which has announced a pair of recalls for certain heavy-duty pickups and SUVs.
The first issue revolves around the 6.7-liter Cummins diesel engine available in the 2010-2014 Ram HD trucks, including 2500 and 3500 series pickups as well as 4500 and 5500 series chassis cabs. In the affected units, "a terminal connector near the fuel heater may be subject to friction-induced corrosion," according to the first of the two announcements from Chrysler below.
The problem could result in overheating and fuel leakage. Chrysler launched its investigation following cases of overheating, none of which actually started a fire, much less an injury or accident. As a precautionary measure, however, Chrysler is instructing service technicians to replace the terminals on an estimated 381,876 Ram units around the world - the vast majority of those (314,704) registered in the US, another 59,432 in Canada, 1,803 in Mexico and 5,937 abroad.

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.
