Sean Guthrie is an American racing driver from Albuquerque, New Mexico. The son of former IndyCar Series driver Jim Guthrie, he is a former Firestone Indy Lights driver and currently competes part-time in the NASCAR K&N Pro Series West.

The 2007 IRL Indy Pro Series was the sixth season of the developmental open-wheel racing series under the Indy Racing League ownership, and the 22nd in Indy NXT combined history, as officially recognized by IndyCar. All teams used Dallara IL-02 chassis, which was fitted with a new wing package, as well as unbranded TWR engines and Firestone tires. In his second season in the series, Alex Lloyd became the runaway champion with Sam Schmidt Motorsports, clinching the title with two races remaining at Infineon Raceway in Sonoma. Lloyd won the first five races of the season, tying Greg Moore's start of the 1995 season for the all-time consecutive wins record in Indy Lights history. Aided by an expanded schedule, Lloyd won eight races including the Freedom 100, and became the third driver to reach that number after Paul Tracy's nine wins in 1990 and Moore's ten wins in 1995.
