The 24-year-old will continue to drive for the leading Toyota outfit in the Sprint Cup series, having signed a multi-year extension of his contract with the team.
Busch joined JGR in 2008 following three full seasons at Hendrick Motorsports, where he claimed Rookie of the Year honours in 2005, making the Chase both in 2006 and 2007, and taking fifth in the championship on his final year with the outfit.
His move to JGR brought immediate success, as he claimed eight wins and the points' lead on his way to making the Chase, before a slump in form and some bad luck dashed his championship hopes in the final ten races of the season.
Last year Busch failed to make the series' 'play-off', despite winning four races during the regular season and he took 13th place in the final standing. He also claimed nine victories and the championship in the Nationwide Series - his first NASCAR title - plus seven wins in the Truck series.
In the latter one, Busch will field his own team in 2010, adding the owner label to his successful, yet young resume in NASCAR.
