2015 Jeep Cherokee finds a bit more fuel mileage thanks to stop/start and aero tweaks

Just a year after it burst onto the scene, Jeep has already made a pretty substantial addition to its V6-powered Cherokee, which has proven to be an extremely popular seller so far for the brand, adding a new stop-start system for the midsize, off-road-ready CUV.
The addition of stop-start included a few aerodynamic tweaks to the Cherokee's polarizing body, resulting in a wallet-pleasing increase in fuel economy. According to the EPA, the front-drive, V6-powered Jeep will now return 21 miles per gallon in the city and 29 mpg on the highway, up from 19 city and 28 highway. Four-wheel-drive, V6-powered Cherokees, meanwhile, will now return 20 mpg in the city and 28 mpg on the highway, up from 19 mpg in the city and 27 mpg.
With 271 horsepower, 239 pound-feet of torque and these newly enhanced figures, it's refreshing to see a larger, naturally aspirated engine that is still able to take the fight to today's crop of small-displacement, turbocharged four-cylinders.

2015 Jeep Renegade Sport 4x4 Quick Spin [w/video]

Which is the most entertaining Jeep Renegade you can get? While one might make an argument for the Trailhawk model and its accompanying off-road hardware and consequential go-anywhere ability, that car comes with one glaring flaw – its 2.4-liter engine and nine-speed automatic transmission just aren't very entertaining. Instead, I submit the turbocharged, 1.4-liter base engine and its accompanying six-speed manual, a position that was reinforced after a recent stint behind the wheel of a very basic Sport 4x4. Not only do you get a fair amount of the Trailhawk's off-road ability – the Selec-Terrain system and a 4WD Lock mode are standard, but you'll be without the 20:1 crawl ratio and Rock off-road mode – you'll also enjoy a more dynamically interesting powertrain. Read on to see why the force-induced Renegade might just be the way to go. Driving Notes My first date with the Renegade was on the mostly empty, winding roads of northern California. There, the 1.4-liter turbocharged inline-four with 160 horsepower and 184 pound-feet of torque felt fine – with no traffic and few stoplights along the drive route, it was easy to keep the engine on boil. But this engine isn't as enjoyable in day-to-day suburban traffic. Power arrives suddenly – peak torque comes between 2,500 and 4,000 rpm – and if you don't use it, you lose it. There's not much oomph in the higher end of the rev range. With such a peaky powerband, it's easy to get caught flat-footed if you're not paying attention. Thankfully the manual transmission makes it simple to stay engaged and in the correct gear. The stick-shift is enjoyable to use, with a firm clutch that's easy to modulate and shift action that isn't sloppy or vague. The 1.4-liter engine sounds good. Turn down the stereo, stomp on the throttle, and you'll be treated to a delicious turbo whistle and a smooth exhaust note. I've said it before and I'll say it again: I want Mopar to offer the Fiat 500 Abarth's exhaust on the Renegade. It'd be fun. If you do prefer the stereo, know that the Renegade's standard four-speaker unit is weak. Base models don't offer Bluetooth or satellite radio, but you can add both of those luxuries, two extra speakers, and a five-inch touchscreen for just $695. Not a bad bargain. The Koni frequency selective dampers do an excellent job of managing both small, frequent imperfections (like freeway expansion joints), and the bigger potholes that still haven't been fixed after the havoc of Detroit's winter.

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.
