So it seems the rumors were true and the Engine Stop-Start (ESS) fuel-saving technology has been confirmed as a standard feature on two bestsellers manufactured by the Chrysler Group - the 2015 model year Jeep Cherokee V6 and the 2015 Chrysler 200 equipped with the Tigershark four-pot.
We already know how the ESS works on the Ram 1500 pickup and operation with the compact SUV and mid-size sedan is not that much different. First of all, it cuts the fuel flow and turns the engine off when the vehicle comes to a halt, saving gasoline and reducing C02 emissions.

"But does that mean the air conditioning stops when the engine turns off?" you might ask. Well, Chrysler was aware of this situation and beefed up the batteries in order to maintain essential vehicle systems like the air con, sat-nav and headlights. When the brake pedal is released, the vehicle senses that input and automatically restarts the car and engages 1st gear in just 0.3 seconds.

The centerpiece of the Engine Stop-Start (ESS) fuel-saving system is a special starter that reduces crank time, translating in quick, smooth restarts. However, if the driver feels like it doesn't want the ESS to intrude, you can always deactivate the eco-conscious feature with the simple push of a button, just like any other stop/start system.

In case of the 2015 Chrysler 200 luxury sedan propelled by the 184 horsepower 2.4-liter Tigershark inline-four mill, the newly introduced ESS system will improve fuel economy by 3 percent in ideal driving conditions. The 2015 Jeep Cherokee fitted with the 271 horsepower 3.2-liter Pentastar V6 is estimated to get the same improvement in fuel economy, while the Engine Stop-Start feature promises to reduce carbon emissions by up to 3 percentage points.

Chrysler says that the ESS fuel-sipping gizmo is scheduled to arrive on the Jeep Cherokee SUV in the third quarter, while the 2015 Chrysler 200 will get it by the end of the year.
