Colin Noble, who is based at the Alex F Noble Nissan dealership in Midlothian, has become the first Scot to be crowned overall champion of the Dunlop Radical UK Cup in its 10-year history.

The event is one of UK motor racing's most popular endurance competitions and becoming overall champion for the first time in his career is the culmination of three decades of involvement in the sport for Noble. He achieved overall victory as a solo driver in the purpose-built Radical SR3 RS 260bhp race car he drove at each of the eight rounds of the competition.

Afterwards the Scot was quick to state that his win owed much to the efforts and "fantastic" support of the Alex F Noble Nissan racing team.

"I've got a great car this year," he said. "It's been a dream to drive but the victory really belongs to the team. We were confident we could put in a strong performance, but not only did we go on to win the championship, we also picked up the prize for the Best Run Privateer Team of the Year.

"The championship has been the highlight of our racing careers so far, made even more special by the fact we've achieved it racing at some of the most challenging tracks in the world, including Brands Hatch, Silverstone and Spa."

The Dunlop Radical UK Cup was contested over 16 races in eight meetings at six circuits between March and October. Five of these were in the UK – Snetterton 300, Brands Hatch Indy, Silverstone GP, Donington Park and Oulton Park International – with the sixth at the famous Spa-Francorchamps circuit in Belgium. Noble was first in five races and finished with a points haul of 198.

The Alex F Noble Nissan racing team will move on to the 2013 Radical European Masters which will be contested at circuits across six countries – including Silverstone in the UK – between March and November.
