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.

100,000 Jeep Cherokee models subject to further 9-speed recalibration

It seems that the software problems with the nine-speed automatic gearbox in the Jeep Cherokee continue to mount. The programming already caused multiple development delays and even postponed the Cherokee's market launch by roughly two months. Now, Jeep has issued another recalibration to hopefully assuage unhappy drivers.
According to Automotive News, this reflash for the allegedly jerky transmission covers over 100,000 Cherokees built before May 5, but it's not technically a recall. If owners are having problems and complain to the dealer, they get the new software. Otherwise, they continue with the current version. New vehicles on dealer lots also receive the latest revision to the programming. It takes only around five minutes to install, but technicians need to take the Cherokee on a test drive to adapt the gearbox to the changes.
The Cherokee's transmission software has been problematic practically since the beginning. The Jeep plant in Toledo, OH, briefly idled its second-shift workers last year to take care of the issue. Since the launch issues for the crossover, demand has been strong. Jeep added another 1,000 temporary workers to the Toledo factory to keep up, and sales were on par with the Wrangler in just its first two months.

Next Jeep Wrangler to get hybrid option?

This may the year a Jeep hybrid is officially announced. Really. The Chrysler division may finally be making plans for its first gas-electric powertrain to help boost the group's fuel economy, says UK's Auto Express, citing Mike Manley, CEO of FCA's Jeep division. The guinea pig of sorts may be the Wrangler, which moved almost a quarter-million units in the US last year. The Wrangler could get a hybrid drivetrain by the 2017 model year, as Jeep executives look to maintain the model's feel and torque while boosting its fuel economy. The Wrangler gets a pretty paltry 18 miles per gallon combined out of its six-cylinder mill, so the bar's set pretty low. Of course, we've heard this talk before. In late 2013, Chrysler Asia-Pacific product planning manager Steve Bartoli told Australia's Drive that a Jeep hybrid was pretty much inevitable, though not much has been mentioned since. FCA could use all the help it can get in the fuel economy department. The group brought up the rear among automakers when it came to fuel efficiency, the US Environmental Protection Agency (EPA) said in its EPA Trends report released last October. The FCA models combined for a 21.1 miles per gallon average for the 2014 model year, compared to the 24.2 mpg overall industry average. The group's only electric vehicle in the US is the low-volume Fiat 500e, though the company may start selling a plug-in hybrid version of its Chrysler Town & Country by the end of the year.
