North American stock car-racing series Nascar has extended its partnership with FanVision, an interactive services company that provides at-track content and technology to fans.
The four-year deal will run through to the end of the 2019 season.
FanVision will continue to provide fans at Sprint Cup Series events with a handheld device that will enable them to access various video content.
Fans can customise content and select to view the live race broadcast, multiple in-car cameras, instant replays, statistics and a scanner to listen to the drivers and their crews.
The FanVision device is available to rent or buy at each race.
