2015 Chevrolet Impala Gets Standard Start/Stop for 2.5L, Drops eAssist Model

Besides the previously announced Bi-Fuel V6 CNG edition that allows the Impala to run on compressed natural gas (CNG), the other news for the 2015MY version of Chevy’s full-size sedan is the axing of the 2.4-liter eAssist model with the “mini-hybrid system”, which is effectively replaced by the updated 2.5-liter base model that gains standard start-stop tech.

Chevy claims that the addition of the new stop-start system that includes a larger heavy-duty starter motor to help with the additional ignition cycles and revised motor mounts, improves the 2.5-liter four-cylinder engine’s city fuel economy by nearly 5 percent, or one mile per gallon.

The Impala 2.5L returns an EPA estimated 22 mpg city, 31 mpg on the highway and 25 mpg combined.

The 2015 Impala will go on sale in the States this summer with a starting price of $27,735 for the 4-cylinder LS model, while the 3.6-liter V6 edition that does not come with start/stop tech, begins at $30,960, with both prices including an $825 destination charge.
