Rocket boys Button and Buncombe fire up the beast!

Jenson Button is in action today at Silverstone.

The 2009 F1 world champion is shaking down the Jenson Team Rocket RJN McLaren 720S that he will share with team co-owner and best buddy Chris Buncombe in next month's British GT finale.

The three-hour race - held on November 7 - will be Button's first on home soil since the Silverstone WEC round held in 2018.

Jenson Team Rocket RJN will also enter their regular car shared by World's Fastest Gamer James Baldwin and Michael O'Brien, who won the British GT season-opener at Oulton Park in August.
