“There was a failure in the cooling system for the hybrid systems, and that was the thing that caused everything to fall apart around it. That was the core of the problem, and it cascaded into a number of other issues. Everything is linked together – the turbo isn’t working very well, and so on. Different things were coming in and out.
“I think if we stand back and analyse the season as a whole we weren’t as reliable as we should have been, but actually the unreliability fell quite equitably in the end. But overall, great to win the race itself. It takes us to 16 wins, and it was great for Lewis.”
