He is a 3-time winner.“Helio has been a valuable member of Team Penske for almost 20 years and we are looking forward to sharing more success together,” Roger Penske said in a release.Castroneves has spent 18 years with Team Penske's Indy Car program and has 30 wins and 50 pole positions.INDIANAPOLIS -- At the end of 500 miles around Indianapolis Motor Speedway, it was a former Formula One driver who took the checkered flag. "But he's just such a gentleman and such a fair player."The Andretti family has struggled for decades to win this race, but as a car owner, Michael Andretti certainly knows the way to Victory Lane. Takuma Sato became the first Japanese winner of the Indianapolis 500 on Sunday when he denied Helio Castroneves a record-tying fourth victory as the two traded the lead in the closing laps."I know Helio is always going to charge," Sato said.“Helping Roger, the team and everyone with Acura start this program and build it from the ground up will be another big challenge and a great opportunity in my career.“I am proud of everything we have accomplished together in Indy Car, and now I am focused on helping to develop the ARX-05 to try and win the 24 Hours of Daytona and the IMSA championship in 2018 with Acura.”Castroneves will return to Indy Car as a one-off driver for the 2018 Indianapolis 500, but the news means that September’s Go Pro Grand Prix of Sonoma was the last race of his full-time Indy Car career.His departure also continues to thin the car count for next season."I know how big this news is going to be tomorrow when they wake up in Japan. I'm really happy for them, that we were able to give them a win with our Japanese driver here."Added Sato about the popularity of his victory in Japan: "This is going to be mega big.A lot of the Japanese fans are following the Indy Car Series and many, many flew over for the Indianapolis 500.
They worked really hard to get us here," said Andretti.We showed the great result today and I am very proud of it."In a Chevrolet for Team Penske, Castroneves briefly took the lead but couldn't make it stick as Sato grabbed it back.
