ISR has announced plans to withdraw from Formula Renault 3.5 in favour of a GT campaign in 2015.

The Czech outfit first joined Renault's flagship series back in 2010 and has been at the forefront of its racing ever since. Daniel Ricciardo, Sam Bird and Sergey Sirotkin have all driven under the guidance of team boss Igor Salaquarda. The team fielded just one car in 2014 with Jazeman Jaafar at the helm.

Salaquarda explained the team's decisions to part ways with Renault, thanking the manufacturers for five years of competition.

"During the last five years we successfully took part in the World Series by Renault 3.5 with our drivers scoring several victories and consequently becoming Formula 1 stars," he said. "Looking to challenging future goals has always been in the DNA of our team and at the end of this year's campaign we decided to focus exclusively on a very high level project in GT racing, which means stopping our participation in the World Series by Renault."

ISR first trialled GT Racing in July this year when an Audi R8 LMS Ultra contested the Spa 24 Hours, signalling a full campaign in the Gulf 12 Hours in Abu Dhabi next month.

"Endurance races have always excited me and the decision was taken with great enthusiasm," Salaquarda continued. "We got our first Audi R8 LMS ultra in July, which permitted I.S.R. Racing to make its GT debut in Spa. Things have evolved since then."

"The whole team is quite excited for this new project and we are all extremely motivated to start on the right foot in this fascinating category."
