“This was done as part of our continuing improvement efforts, to make the product better, to respond to the demands of our customers, and what they expect from the product as we go along. So it’s likely that some customers may experience an improvement in range over previous model years,” General Motors manager of electrification technology communications, Kevin Kelly, told AG.
This is the second time the Volt’s battery unit has increased since the model was introduced. In 2013, Chevrolet replaced the Volt’s original 16 kWh battery with a 16.5 kWh unit, resulting in the Volt’s all-electric range rising from 35 miles to 38 miles and its efficiency improving from 93 MPGe to 98 MPGe.
AG reports that the EPA has yet to certify the Volt’s new battery for range and efficiency ratings; however, the Volt is expected to travel 40 miles on electricity before relying on its gas-powered generator.
