DETROIT -- Chrysler Group will equip some 2015 Jeep Cherokees and Chrysler 200s with engine stop-start as a standard feature beginning later this year, the automaker said today.
The fuel-saving technology shuts off the engine as the vehicle brakes to a stop and restarts it when pressure on the brake pedal is released.
The automaker said it intends to put the feature in its 3.2-liter V-6 versions of the 2015 Jeep Cherokee when they go into production in the third quarter.
It also will install stop-start in 2.4-liter inline-four versions of the 2015 Chrysler 200 sedan beginning in the fourth quarter.
The addition of stop-start to the Ram 1500 pickup resulted in a 1 mpg increase in its city fuel economy rating, Chrysler said. The most fuel-efficient version of the Cherokee that will receive stop-start is rated at 19 mpg city.
The most fuel-efficient Chrysler 200 that will get stop-start is rated at 23 mpg city.
Stop-start will not be available on Cherokees powered by the 2.4-liter I-4 and Chrysler 200s powered by the 3.6-liter V-6 engines, a Chrysler spokeswoman said.
Chrysler said it estimates that adding stop-start to the two vehicles will improve their fuel economy and reduce emissions by up to 3 percent.
The Cherokee and 200 share the same platform and many drivetrain components, including Chrysler’s nine-speed automatic transmission.
