Stop Start Technology Standard on the 2015 Impala

To boost the 2015 Impala’s fuel economy Chevrolet is implementing stop-start technology. Chevrolet says this technology will increase the car’s fuel economy by 5%. The stop-start technology will only be offered standard in the 2.5 liter 2015 Impala. Chevrolet has already used the stop-start in the four cylinder 2014 Malibu. This technology only works in certain situations, for instance in stop and go traffic the stop-start technology turns off the engine which reduces the amount of fuel the engine consumes.
