26 Marco Andretti Andretti Green
Hometown: Nazareth, Pa.
Notable: He failed to finish seven times in 2008, derailing a season in which he led 330 laps, fourth-most in the series. His lone career win came in his rookie year, 2006, at Infineon.

Notable: A veteran movie and TV stuntman and a stock car driver with experience in all three top NASCAR series, Barrett has longtime crew chief Owen Snyder to aid his transition into IndyCar.
6 Ryan Briscoe Team Penske

20 Ed Carpenter Vision Racing

11 Tony Kanaan Andretti Green
Hometown: Salvador, Brazil
Notable: The 2004 champ didn't have a great '08 — but perhaps only by his standard. He won at Richmond to extend his streak of seasons with at least one victory to six and was third in points.

13 E.J. Viso HVM Racing
Hometown: Caracas, Venezuela
