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.

Next-gen Jeep Wrangler to pack 300-hp Hurricane turbo four

Fiat Chrysler has been working for some time now on a new turbocharged four-cylinder engine. Dubbed "Hurricane," the engine is now said to produce nearly 300 horsepower. And its first application could be in the next-generation Jeep Wrangler. With that much power coming from such a small engine, the Hurricane would offer an even higher level of specific output than the 1.75-liter engine in the Alfa Romeo 4C – one of FCA's highest-stressed engines – far eclipsing the 4C's 120 horsepower per liter with 150 hp/l. By way of comparison, the latest 2.0-liter, four-cylinder version of Ford's EcoBoost engine produces "only" 245 hp (122.5 hp/l). The 2.0-liter turbo four in the latest Mercedes-AMG CLA45 and GLA45, however, produces 375 hp. To get so much out of so little an engine, FCA will utilize a twin-scroll turbocharger and variable valve timing. That could make it ideally suited towards a compact performance model, but according to Automotive News, its first application could be in the new the Wrangler. The larger 3.6-liter Pentastar V6 produces 285 hp, nearly as much as the Hurricane will. But with a smaller engine, an eight-speed transmission, and aluminum construction, the new Jeep will likely benefit from dramatically-improved fuel consumption. Related Video:

2016 Jeep Wrangler recalled over impact sensor wiring

Fiat Chrysler just announced a pair of recalls totaling nearly 311,000 units. The bigger recall affects certain 2016 and 2017 model year Jeep Wranglers. Although, since FCA claims all of the affected 2017s are in the company's hands, really, only 2016 owners should pay attention here. The affected Wranglers suffer from an issue where wiring disconnects from impact sensors in certain types of crashes, potentially preventing the airbags and pretensioners from activating. FCA uncovered the problem in what its press release calls "a routine, in-house crash test" and claims "service availability is imminent." The affected Jeeps require a simple rewiring. The other recall, announced Tuesday, is more of a fleet issue, affecting 2007 to 2013 model-year Ram 2500 and 3500 pickups and 3500, 4500, and 5500 chassis cabs and 2011 to 2014 Dodge Charger Pursuit police vehicles. There's a problem with "premature diode wear" in alternators that are subject to "frequent load cycling, at or near maximum amperage, [or] in hot ambient temperatures." Affected alternators could short out, causing a vehicle to stall or potentially catch fire. FCA lists 182,743 affected Wranglers in the US, 18,011 in Canada, 3,087 in Mexico, and 20,948 in global markets. The Ram/ Charger Pursuit recall lists 74,833 vehicles in the US, 10,077 in Canada, 1,088 in Mexico, and 134 outside the NAFTA region. Of all those vehicles, the Jeep recall hasn't caused any injuries or fatalities, while FCA says it's aware of one "potentially related injury" and no accidents due to its fleet vehicle recall. FCA says it will notify owners/operators of affected vehicles when service appointments are available. As per usual, all the work is free of charge. Related Video:
