Well it had been on the cards for the last two hours but sadly the Andretti Green Racing Acura has now retired with just over 1.30mins left. The reason for retirement was overheating of the engine and its components.

The team had been aware of issues with cooling for some time, and yet still managed to keep up with the faster cars.

As they have completed more than 70% of the race they will still be eligible for points .
