Already Having wrapped up the British Formula Three International Series championship with his third place in the final race at Rockingham Felipe Nasr could clinch another title this weekend at Donington.

Though both previous editions of the Sunoco Rolex 24 At Daytona Challenge have come down to the final races of the season – falling in favour of first Derek Johnston in 2009, then Ross Kaiser last year, Nasr could seal the third year of the Challenge before the final point scoring weekends.

Nasr’s 2011 domination of the single seater category has also given him a commanding lead in the Sunoco Challenge, and a single pole position from the two on offer this weekend will give him an unassailable lead – and the prize of a drive in a Daytona Prototype in January's Rolex 24 at Daytona.

Nasr will begin the Donington Park weekend with a points score of 85, well clear of the 53 of his nearest challenger, British Endurance Championship driver Javier Morcillo.

His advantage means he needs to total just 12 points to clinch the title, and with 20 points available for pole position a fourth qualifying topping performance of the season will put his name on a plane ticket to Florida.

Should the Brazilian miss pole position then a finish anywhere better than eighth place will give him the necessary points to win the Sunoco Challenge before the final points scoring rounds of the season.

Of course, it is possible that Nasr will fail to score the points he needs – unlikely as he only has three finishes worse than eighth in the season to date – leaving the door open to Avon Tyres British GT driver Matt Griffin to close back in, and take the 2012 Sunoco Rolex 24 at Daytona Challenge into the final weekend of Formula Three and GT competition at Silverstone (October 8-9).
