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.

Dodge Challenger spied exercising supercharged Hellcat Hemi V8

One of the prime complaints against the Dodge Challenger is that, even in SRT8 guise, its 470 horsepower is responsible for hauling over 4,200 pounds of vehicle. For comparison, the 420 hp in the Ford Mustang GT only has to deal with 3,618 lbs. Things only get worse from there, as the higher-performance variants of both the Mustang and the Chevrolet Camaro are far more powerful than an SRT8 without adding on much heft.
So what is Chrysler to do? The correct answer is add a whole lot more grunt to its hefty two-door and even the odds. That's where the all-new Hellcat engine comes into play. We reported on this engine in May, and suggested that the Hellcat, a supercharged powerplant based on a 6.4-liter V8, would easily generate 500 to 570 hp and could likely arrive boasting more than 600 ponies.
Chrysler's ace in its sleeve has now been spied testing, with a number of Hellcat-equipped Challengers running the potent new engine both in more urbanized areas and under the sun of Death Valley. The hoods on these testers have been raised to accommodate the engine, and that camouflage over the fascias of these prototypes is there to hide a larger air intake. We also note what appears to be a new split grille under wraps. As for power output, our spies are now suggesting a Viper-equalling 640 hp from the Hellcat-equipped cars.

Ford and Chrysler reducing summer plant shutdowns

Most domestic automaker assembly plants traditionally take a couple of weeks off during the summer. The shutdowns give each plant time for much needed repairs and maintenance, and in some cases, help better align production with demand. Not this year, though, as demand for many models is outstripping what Ford, Chrysler and General Motors plants can produce.
Ford has announced that it will shorten its annual summer shutdown for most North American plants from two weeks to one. The shorter shutdown will increase the carmaker's annual North American production by 40,000 units on top of the 200,000 extra units that it was already planning to produce this year versus last. Automotive News reports that Ford produced 2.8 million vehicles on this continent in 2012, and that output this year has already increased 13 percent through April.
Chrysler, meanwhile, is also operating at full tilt and plans to run some plants through the summer with no shutdown at all. Those not getting a break include Jefferson North where the Jeep Grand Cherokee and Dodge Durango are assembled, Toledo North that will assemble the new Cherokee, and Conner Avenue, home of SRT Viper production. Other assembly plants will be down for a single week, while all of Chrysler's engine and transmission plants except one in Indiana will continue operating with no shutdown this summer.
