The Nissan GT-R has scored its first major GT1 World Championship victory in Portugal at the weekend with Germany's Lucas Luhr and Michael Krumm taking victory in Round 3 of the 2011 series at the Portima circuit ahead of an International field of Italian, British and American GT cars.

The Nissan GT-R swept to victory in the 34-lap main race after their JR Motorsports British teammates Richard Westbrook and Peter Dumbreck struck mechanical problems while leading.

Underscoring the Nissan GT-R's dominance of the Portuguese round, Australia's David Brabham and Britain's Jamie Campbell-Walter finished third in their Sumo Power Nissan, behind the Aston Martin of Stefan Mucke and Darren Turner, but ahead of three Lamborghinis and a Ford GT, while their Nissan GT-R Brazilian team-mates Enrique Bernoldi and Ricardo Zonta took eighth place.

Nissan's domination of the Portuguese GT1 round began in official qualifying, when all four of the competing Nissan GT-Rs occupied the top four positions.

The Nissan GT-Rs then stormed to an historic 1-2-3 finish in the qualifying race - the first ever podium lockout by a single manufacturer since the GT1 series' formation.

The weekend was doubly successful for Nissan motorsport, with the Nissan-powered TDS Racing Oreca of Beche/Thiriet/Firth taking victory in the LMP2 Class in the 1000 kms of Spa ahead of the similarly Nissan-powered Boutsen Energy Racing Oreca of Kraihamer/De Crem.

Fifth place in LMP2 at Spa also went to Nissan, with the Signatech Nissan, driven by Nissan's GT Academy graduate Lucas Ordonez and his teammates Franck Mailleux and Soheil Ayari.

The next major challenge for the Nissan-powered LMP2 cars is the annual 24 Hours of Le Mans on June 11-12.
