 The 2011 Volt was not submitted for application to the California Air Resources Board 's ( CARB ) Clean Vehicle Rebate Project rebate and therefore was not required to meet the 10 @-@ year 150 @,@ 000 @-@ mile ( 240 @,@ 000 km ) battery warranty requirement for enhanced advanced technology partial zero @-@ emissions vehicles ( enhAT @-@ PZEV ) . The Volt team explained that for the launch General Motors decided to go with a common national package which includes an 8 @-@ year 100 @,@ 000 @-@ mile ( 160 @,@ 000 km ) battery warranty . For this reason owners of the 2011 Volt did not qualify for California 's rebates and free access to use carpool lanes even when traveling solo . A third package , scheduled for 2013 , is under development with an E85 flex @-@ fuel engine . General Motors engineering team commented that " introducing two or three packages of an entirely new technology set and platform at the same time wasn 't an option . "
