driver errors and incidents. The team failed to win major IndyCar silverware for the first time since the 2005 season. On November 9, 2007, Sam Hornish Jr. announced he would depart from IndyCar Series to the NASCAR Sprint Cup Series, driving full-time for the 2008 season with Team Penske American Le Mans Series confirming Porsche LMP2 driver Ryan Briscoe as Castroneves's new teammate for 2008 on November 13, 2007. Team Penske started the 2008 season poorly but Hélio Castroneves posted five top-four finishes (including two 2nd-place finishes) to start the year. Meanwhile, Ryan Briscoe was forced to adapt the Penske IndyCar car, as Briscoe was entering his first season with Team Penske after spending two years as an IndyCar part-timer whilst he raced in the Champ Car World Series in 2006 and later the American Le Mans Series in 2007. Ryan Briscoe finally scored his first win at the Milwaukee Mile while Castroneves claimed his first 2008 win in Infineon Raceway. Castroneves nearly won the championship at Chicagoland Speedway, but Scott Dixon finished in 2nd place to ensure his 2008 IndyCar Series driver's title. For 2009, Verizon Wireless, joined ExxonMobil (McLaren's then fuel and lubricant partner) as associate sponsors, and the team was billed as Verizon Championship Racing. The third car was driven by Will Power (originally a substitute for Castroneves) and carried the No. 12 and featured primary sponsorship of both the Verizon Wireless brand and Roger Penske's truck rental business. For the 2010 season, the team entered their fifth year of its Penske-Honda partnership with Will Power promoted to a full-time Penske seat alongside Castroneves and Briscoe. Team Penske became a three-car team for the first time since 1994, with the addition of a full-time team for Power. Team Penske started the 2010 season in style by winning the first three races of the season. Will Power challenged for the driver's title until suspension failure in the season finale at Homestead-Miami Speedway robbed him of a shot at the championship. Penske ended up finishing the 2010 season with nine wins, thirteen pole positions, and six fastest laps (mostly by Will Power). On 12 November 2010, Penske confirmed that they would end their partnership with Honda at the end of the 2011 season and use engines supplied by Chevrolet for the 2012 season. For the 2011 season, the team entered their sixth and final year of its Penske-Honda partnership.
