To celebrate its sponsorship of the Goodwood Festival of Speed and the Supercar Paddock, Michelin has published a special-edition I-Spy Goodwood Festival of Speed book.

In the tradition of I-Spy books from past and present, the new book is packed with interesting cars, places and people to spot at this year's Festival and even gives petrolheads (over the age of 21) the chance to win a Porsche driving day at Silverstone by entering a free prize draw. The winning driver can also bring a guest passenger as long as they are at least 12 years old.

The book is divided into sections covering all the elements of the Festival including the Michelin Supercar Paddock, the Moving Motor Show, the Action Sports Arena, the Forest Rally Stage and the Exhibition Area. Readers have to spy cars, tyres, Goodwood landmarks, the Michelin Man, and even aircraft to complete the book and qualify for an I-Spy badge and certificate.

The book will be available on the Michelin stand at the Festival from Thursday 28 June to Sunday 1 July, while stocks last.

For those who cannot attend or who can't wait until the Festival there are just 500 copies available for pre-purchase from the Michelin I-Spy website for £3.50 including P&P.
