IndyCar has signed a two-year extension with Verizon Wireless that expands its sponsorship to cover the pole award.

The pole award contingency money and trophy will be for all 19 IndyCar races beginning with Sunday's season-opener through the streets of St. Pete.

Verizon will mark the award with a gold medallion on the rear wing endplate of the pole-winning car each week. The medallion will be changed to silver following the event, and each subsequent pole earned will be represented with a star on the medallion.

Verizon is also planning enhancements to the IndyCar 13 app that's available on Verizon Android OS and all-carrier Apple iOS smartphones and tablets.
