Jeep Wrangler diesel likely after 2015 model refresh

We automotive journalists aren't always the right people to ask about whether a US-spec vehicle should or should not be offered with a diesel powertrain (hint: the answer is usually "YES"). But when it comes to the iconic, off-road-ready Jeep Wrangler, we aren't the only ones who have been clamoring for an oil-burning engine behind that famous seven-slat grille. To that end, it appears there's good news on the horizon, as Jeep CEO Mike Manley recently told Ward's Auto that the "Wrangler is on the radar to get (a) diesel."
"I'm confident that the Grand Cherokee will show just how large a demand there is for diesel, and I think what that will do is reinforce the need for us to target Wrangler as a vehicle that can take a diesel," Manley told Ward's. The most rugged of Jeeps is scheduled to get an overhaul around 2015-16, and the diesel powertrain will likely be introduced around that time.
This year alone, Chrysler will be adding a diesel engine to the Grand Cherokee SUV, as well as the Ram 1500 pickup and Promaster utility van.

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.

Some Jeep Cherokees and Chrysler 200s to get standard stop-start in 2015

Automakers the world over are striving to find ways to make their models more efficient, and Chrysler has a solution for some versions of the 2015 Chrysler 200 and 2015 Jeep Cherokee (2014 model shown). The Tigershark 2.4-liter four-cylinder in the 200 and the 3.2-liter Pentastar V6 in the Cherokee are getting a slight boost later this year thanks to the addition of Chrysler's Engine Stop-Start system as standard equipment. The company predicts modest gains - a three-percent improvement in fuel economy and a three percent reduction in CO2 emissions with the new tech compared to without it. While it's not much, those who sit in traffic a lot may see a difference.
Chrysler's stop/start system uses a high-speed starter motor to restart the vehicle in a claimed a third of a second. It works by detecting when the vehicle comes to a stop and turning off the engine. A more powerful battery maintains all of the model's accessories while it sits. When the driver lets off the brake, the car starts up again to drive away. There is even a button in the cabin to turn the ESS off, if desired.
The Jeep will be the first to receive ESS in the third quarter of this year to coincide with the start of production of the 2015 model-year version. The 200 will follow in the fourth quarter as a rolling change in production.
