The 2009 world champion will be in action on the Sunday of the event.
The 2009 world champion will drive the 1968 RA301, which was developed in partnership with Lola Cars and following the Japanese manufacturer's exit at the end of that year, was Honda's final factory-entered F1 car until the 2006 RA106 – which coincidentally, was the car Button took his first F1 win in.
Button's appearance at the Festival of Speed, which will be on the Sunday of the event, will also include a live Q&A session at 1:30PM.
As well as Button, the 2018 Honda works British Touring Car Championship team will be in attendance with triple champion Matt Neal and season rookie Dan Cammish driving the new-for-2018 Civic Type R BTCC car up the hill. The NSX supercar will also be in action, driven by Nick Robinson, one of the leading engineers who worked on the car's development.
'To celebrate the 25th anniversary of Goodwood Festival of Speed, Honda UK has focused on bringing its racing heritage to life by providing unique and engaging experiences to get visitors up close and personal with our products, teams and drivers,' said David Hodgetts, managing director at Honda UK. 'For instance, using a tablet computer, visitors can go for a virtual spin in a Civic with BTCC stars Matt and Dan where they showcase the features of the car. Whilst those who have a passion for the Isle of Man TT have the chance to do a lap of the course while sat on a Fireblade – both experiences from the comfort of our Goodwood stand.'
