Some 2015 Jeep Cherokees and Chrysler 200s will feature engine stop-start as a standard starting later this year. Chrysler Group will feature the technology as standard on the 3.2-liter V-6 versions of the 2015 Jeep Cherokee when it starts building them in the third quarter of this year. The carmaker will also feature the technology in its 2.4-liter inline-four versions of the 2015 Chrysler 200 sedan starting fourth quarter of 2014.
Stop start saves fuel by shutting off the engine when the vehicle brakes to a stop, then restarting it when the driver release his foot from the brake pedal. Chrysler remarked that the addition of stop-start to the Ram 1500 pickup lead to a 1-mpg hike in its city fuel economy rating.
On the other hand, the most fuel-efficient version of the Cherokee receiving the stop-start technology is rated 19 mpg city while the most fuel-efficient Chrysler 200 to get the feature is rated at 23 mpg city.
Chrysler will not make the technology available on 2.4-liter I-4 versions of the Cherokee and the 3.6-liter V-6 variants of the 200, according to a Chrysler spokeswoman. The carmaker expects that featuring the technology on the Cherokee and the Chrysler 200 will help improve fuel economy and cut carbon emissions by up to 3 percent.
