Yesterday, we told you that the upcoming Buick Envision compact crossover will be offered with GM’s turbocharged 2.0-liter I4 Ecotec engine. But not only will the boosted four-banger likely serve as the range-topping powerplant for the new crossover, but it will also feature Stop-Start technology — a first for GM’s highly-acclaimed 2.0-liter turbo (LTG) engine.
Stop-Start shuts down the vehicle’s engine when the vehicle is at a standstill, such as at stoplights. When that happens, a more robust battery continues to power the vehicle’s various functions such as HVAC, radio, and other accessories. The engine seamlessly springs back to life to propel the vehicle when the driver lifts his or her foot off the brake pedal.
Depending on vehicle application and implementation, Stop-Start has the potential to significantly improve fuel economy. For instance, when General Motors first implemented an engine with Stop-Start on the revised 2014 Chevrolet Malibu, the sedan’s fuel economy increased by a healthy 3 MPG in the city and 3 MPG combined.
