The Chevrolet Impala was completely redesigned for 2014, but there are changes already for the 2015 model year. While it adds a new compressed natural gas edition, the 2015 Chevrolet Impala dumps the optional mild-hybrid system offered briefly last year, and replaces it with a standard stop-start feature.

With only two available engine options (the 2.5-liter four-cylinder and the 3.6-liter V-6), this means that the 2015 Chevrolet Impala will not be offered with the Eco model, which paired the 2.4-liter four-cylinder with a mild-hybrid system. The 2015 Impala will lose the Eco’s 25-mpg city and 35-mpg highway EPA fuel economy ratings, the base engine gets slightly more efficient with the addition of stop/start. Stop/start will not be offered on the V-6 models.

Standard on all models with the four-cylinder engine, stop/start helps improve the fuel economy of the 2015 Chevrolet Impala by 1 mpg city, which results in official fuel economy estimates of 22 mpg city and 31 mpg highway.

On the hardware side, new motor mounts and a heavy-duty starter are the key upgrades over the 2014 Impala, while new software helps account for all possibilities when shutting off and restarting the engine including what is called a “change-of-mind event.” This is when the driver attempts to come to a complete stop, but before the engine fully shuts off, the driver accelerates quickly.

Despite the addition of stop/start, the base price of the 2015 Chevrolet Impala has only risen by $65 over the 2014 model year with a new MSRP of $27,735 for the Impala LS. If you’re looking for more power, the base Impala LT V-6 now starts at $30,960. The only other pricing available for the 2015 Chevrolet Impala is for the CNG-equipped models, which have a starting price of $38,210. Standard gas-only Impala models will go on sale this summer, while the CNG Impala will hit dealers closer to the end of the year.
