McLaren has announced that it will unveil its 650S GT3 at the 2014 Gulf 12 Hours race to be held at Yas Marina Circuit in Abu Dhabi in December.
The car has completed the development programme and is reportedly going to face the toughest test of endurance and performance in Abu Dhabi.
McLaren GT Managing Director Andrew Kirkaldy said: "The development programme of the 650S GT3 has been extensive already, with the team testing over thousands of kilometres in various conditions.
"The Gulf 12 Hour will give us the opportunity to fully evaluate the 650S GT3 in a real life race environment, which presents a very different challenge. It will be the toughest test the 650S GT3 has faced so far - a real race situation with a highly competitive grid in high ambient temperatures."
After its final test, the car is expected to be available commercially to customers across the world in 2015.
The 650S is powered by twin-turbo V8 engine and carbon-composite monocoque, and consists of enhanced suspension, transmission and bodywork.
