Jenson Button will give the 'enhanced' McLaren MP4-12C sports car its world debut at the Goodwood Festival of Speed this weekend.

The 2009 F1 world champion will take to the famous Goodwood Hill in a Production Prototype version of the revised 12C on Saturday, June 30.

In addition, McLaren GT will unveil a McLaren 12C GT3 race car adorned with a unique livery, which highlights McLaren Group's support of the 'GREAT' campaign launched this year by the Prime Minister's Office and Department for Culture, Media and Sport. The GREAT campaign is designed to 're-affirm Britain's international reputation and deliver long-term economic benefits through additional tourism, trade and education'. The new MP4-12C model from McLaren will be available to view up close throughout the Festival of Speed in the Goodwood Supercar Paddock.
