Juan Pablo Montoya will return to IndyCar to race for Penske in a third car next season.
The ex-Formula 1 driver and 1999 CART champion has spent the last six and a half years in NASCAR, but will split with his Earnhardt Ganassi team at the end of 2013.
Montoya will join Helio Castroneves and Will Power as Penske returns to a full-time three-car line-up after fielding AJ Allmendinger in an occasional extra car this year.
“I am really excited to join this legendary team beginning next year,” said Montoya.
“I have had the opportunity to drive for some of the best racing teams in the world and I have always admired Roger Penske and his organisation.
“I consider it an honour to be offered the opportunity to drive for Team Penske.”
The 37-year-old Colombian won the CART title at the first attempt when he came to America as a Williams F1 protege and Formula 3000 champion in 1999.
He then added an Indianapolis 500 triumph the following year (pictured) before starting his F1 career with Williams in 2001.
Team owner Roger Penske said Montoya’s career achievements – which include challenging for the 2003 F1 title, winning seven grands prix and two Daytona 24 Hour races – proved he would be a contender back in single-seaters.
“Juan is a proven winner at all levels of motorsport,” said Penske.
“He has won a lot of races and championships and he has an extremely passionate fan base.
“We look forward to building on his successes together and we believe he will be a great addition to Team Penske.”
