Clay Regazzoni during the ‘Race of Champions’ meeting at Brands Hatch on 21 March 1971 aboard his Ferrari 312B2 ‘005’…
He won the race by a little over 20 seconds from Jackie Stewart’s Tyrrell 001 Ford, John Surtees Surtees TS9B Ford and Tim Schenken’s Brabham BT33 Ford.

It wasn’t a bad season for Ferrari, in other non-championship events Mario Andretti won the Questor GP at Ontario Speedway and Jacky Ickx the Jochen Rindt Trophy at Hockenheim. In the more serious stuff the same pair won in South Africa, Kyalami and Holland, Zandvoort respectively.

It was a Tyrrell year though, the new marque won six races- Stewart 5, and Cevert 1 in a season which demonstrated the organisation and commercial acumen of Ken Tyrrell, the design prowess of Derek Gardner, and the power, torque and reliability of the still youthful, ubiquitous Ford Cosworth DFV 3 litre V8. Let’s not forget the talent of the two drivers, Stewart at his peak and Cevert on the ascent.
In terms of arcane minutae it appears to be right at the time the charismatic Swiss considered and switched from his old-school Bell Magnum to a full-face Bell Star helmet- he certainly raced at Brands with the ‘Star albeit without his distinctive trademark red on white band and cross.
