The ultimate Scalextric track built for Chris Evans' CarFest South will be sold off after the event at an auction to raise money for Children In Need.

Created by Hornby, the Ultimate track is 45-metres long and is made up of 177 pieces. The track has been designed with the best corners and chicanes from numerous real-life race tracks.

Included in the design are scaled down sections such as the Ascari Chicane from Monza in Italy, Casino Square from Monaco, Copse from Silverstone's GP track and the Wall Of Champions from Circuit Gilles Villeneuve in Canada.

It was designed by Martin Brundle, former F1 driver and now a commentator on the sport.

He said: "The team challenged me to design my dream circuit using sections from the races in 2015. I immediately wanted a figure of '8' like our beloved Suzuka, and could only dream of driving a series of corners such as scaling the mountain up to turn one in Austin before falling through the 'Senna S' of Brazil and towards Silverstone's fearsome Copse corner.

"And that's just a small section. Now amazingly, we've built a model and so I will revert to my childhood for many laps. It's going to get competitive."

CarFest South runs from 29-30 August and afterwards the Ultimate Scalextric track will be auctioned off.

Guy Lees-Milne, general manager for Classic Car Auctions, said: "We'd like to thank Hornby once again for allowing us to auction this amazing circuit in our sale at CarFest. We're sure there will be plenty of interest and hope to generate a fantastic sum for charity."
