Honda has announced that Hideki Mutoh will end his IndyCar Series stint and switch to Japan's Super GT category for 2011.
The 28-year-old has competed in America since 2007, when his second-place finish in Indy Lights led to a promotion to IndyCar. He spent two years with Andretti Green Racing before joining Newman/Haas last year, with a second place at Iowa in 2008 his best result.
Mutoh will now be paired with Japanese Formula 3 N class champion Takashi Kobayashi in an Aguri Suzuki-run Honda in Super GT.
With Mutoh leaving the series, KV Racing's Takuma Sato looks set to be Japan's sole full-time representative in the IZOD IndyCar Series this season.
