On 16 March, the "Brands Hatch Six-Hours" was run and saw a healthy invasion of Italian cars; Lancia Beta Monte Carlos in the hands of Riccardo Patrese and Walter Röhrl, with Michele Alboreto and Eddie Cheever taking the two places for Lancia Corse, the winning car being the only one to complete the full race distance of 147 laps, at 99.384 mph. In third spot a further lap down was the De Cadenet LM of Alain de Cadenet and Desiré Wilson. This was Alan Jones's World Championship year and on his way to the crown he won the "Marlboro British Grand Prix" on 13 July, in a Williams-Cosworth FW07B from Nelson Piquet and Carlos Reutemann. Piquet's Brabham-Cosworth BT49 split the two Williams, Derek Daly and Jean-Pierre Jarier filling the next spots for Tyrrell, with a young Frenchman, Alain Prost for McLaren in sixth. There was a slimmed down calendar in 1981 with but one International, the emphasis being on top-class national racing.
