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. Penske's trio of Castroneves-Briscoe-Power remained for the second consecutive year while the team lost the ExxonMobil sponsorship to Stewart-Haas Racing's NASCAR team in favor of Shell and Pennzoil as their official motor oil partner. The team started well by two victories from Will Power in the first five races. Power captured his first oval win at Texas Motor Speedway, and came into the season finale at Las Vegas 18 points behind leader Dario Franchitti. However, on lap 11 of the race, Power was collected in a fiery 15-car crash that killed defending Indianapolis 500 winner Dan Wheldon. The race was cut short in Wheldon's honor and the championship points stood as they had entering Las Vegas, giving Franchitti his third consecutive driver's title (and fourth overall). Penske finished the 2011 season with six victories, all from Will Power, while Castroneves and Briscoe went winless.
