Sportvision's RACEf/x technology, the most advanced tracking technology created for televised sports, is now utilized in all three NASCAR national series after expanding to the Truck Series in 2012. Like Sprint Cup Series and Nationwide Series cars, the trucks are equipped with Vector II tracking devices. These devices are the latest generation of Sportvision RACEf/x technology and the first to utilize both Global Positioning Satellites (GPS) and Global Navigation Satellite System (GLONASS) satellite navigation systems.
The technology debuted in the Sprint Cup Series at the 2001 Daytona 500 and was introduced to the Nationwide Series in 2007. This patented, state-of-the-art technology tracks the cars at speeds reaching 200 MPH to create a complete "digital record" of a NASCAR race in real-time. With the addition, SPEED will now highlight a full slate of broadcast graphics during Truck Series broadcasts and the technology will continue to be an integral component utilized by other NASCAR broadcast partners through 2018.
