Porsche has completed a five-day tyre test at the Abu Dhabi circuit with its 2016 WEC challenger, lapping the Formula 1 layout of the circuit more than 740 times.
The reigning World Endurance Champions also took the opportunity to trial some new components for the Porsche 919 Hybrid, including powertrain and hybrid developments as well as aerodynamic comparisons.
Timo Bernhard, Brendon Hartley and Mark Webber took turns to complete a total of 4,142km of running.
The trio spent three days focussing on Michelin's new slick tyres, of which there are three variations to analyse, before the team will make a final decision on which compounds to use during the 2016 WEC season.
Speaking after the test, team principal Andreas Seidl said: "We are very pleased with this test. It is a demanding and important task to make the right choices out of the variety of tyres, as we will spend the season on them.
"Consistent conditions are essential to get reliable results. In Abu Dhabi we didn’t only have dry conditions, but also constant temperatures. We can’t find such conditions in Europe at this time of the year."
The 919's final test ahead of the season will take place in Europe, with a focus on aerodynamic development.
