Roger Penske announced a switch to Chevrolet powerplants for the 2012 IndyCar Series season. Once again, Penske would dominate the early portion of the season, winning 4 consecutive races, with Castroneves taking the season opener at St. Petersburg, and Power capturing wins at Barber, Long Beach, and São Paulo. Briscoe would have struggles throughout the season, but managed to find victory lane at Sonoma. However, Power would come up short in the championship after a crash at the season finale. Briscoe left the team after 2012 for other opportunities.
