A carbon fibre soapbox racing car driven by motorcycling legend Barry Sheene is to be sold at auction.

Sheene swapped his usual two wheels for four to take part in the soapbox racing challenge at the 2000 Goodwood Festival of Speed, near Chichester.

Participating vehicles had to cost no more than £1,000.

Auto engineering company Cosworth built the car for Sheene and it will be sold at its headquarters in Northampton on 19 July.

It was Goodwood's first-ever soapbox race and the motorcyclist competed against 24 other drivers.

H&I Auctions, which will run the auction, expect the vehicle to sell for "at least four, if not five figures", but the company has not set an estimate.

Sheene won 19 races and two world championships during his 11-year 500cc Grand Prix career, which ended in 1984.

He defied death twice after two major crashes that could have ended his career.

After emigrating to Australia, he died of cancer aged 52 in 2003.
