 Beginning in 2013, the livery layout for the NASCAR Cup Series was altered, coinciding with the change to the Generation 6 model car.In lieu of the series sponsor like in lower series, the windshield prominently features the last name of the driver (as well as first name or first initial in the case of siblings and family members, as is the case for both Busch brothers, or suffixes for drivers such as Dale Earnhardt, Jr. and Martin Truex, Jr.) placed in the center of the windshield header.Logos of the manufacturer are placed on each corner of the upper windshield.
