The biggest free agent signing in Autobacs Super GT Series history is now official.

2009 Formula 1 World Champion Jenson Button announced during a talk show event at the Honda Racing Thanks Day in Twin Ring Motegi that he will be racing in Super GT full-time with Honda in the GT500 class.

Button, a veteran of over 300 Formula 1 Grand Prix starts, made his Super GT debut with Team Mugen in the Suzuka 1000km – and has long had his sights on a full-time drive in the series ever since.

“It’s been a dream for the last couple of years, I love the category,” said Button of Super GT. “I did one race at Suzuka earlier in the year, and it got me very excited – I’m very excited about the new season!”

“There’s a lot of testing to be done – to feel comfortable (in the car), and to hopefully improve the package, and go out next year and be competitive.”

No announcement of a team or co-drivers was made, we can expect that information to be revealed by February, when Honda announces their 2018 motorsports activities.
