2015 Chevrolet Impala Comes With Standard Stop/Start Technology
Although the Chevrolet Impala was completely redesigned for the 2014 model year, it will receive a few tweaks for 2015. The new Impala will come standard with stop/start technology, which will help boost fuel economy slightly. GM employed its experience with eAssist mild hybrids to help improve fuel economy on the 2014 model, and the company made further improvements for the new model year. Impalas equipped with 2.5-liter four-cylinder engines will achieve 22 mpg in the city, an improvement of one mpg over last year. Its highway fuel economy comes in at 31 mpg. Models with the 3.6-liter V-6 engine will not receive the stop/start technology. GM has made changes to its stop/start technology to improve quality. Revised motor mounts provide insulation and prevent noise and vibration from entering the cabin. The software is also able to adapt to "change-of-mind events" when the driver begins to stop but then quickly accelerates. “Stop/start system customer research indicates they want the engine to start up as quickly and smoothly as possible after a stop,” said Mark Meyers, manager of Chevrolet Global Vehicle Performance, in a statement. On sale this summer, the 2015 Chevrolet Impala is priced similarly to the outgoing model at $27,735 with the four-cylinder LS model. Six-cylinder LT models begin at $30,960. These charges include a destination and handling fee. Source: General Motors
