"The result of the first race looks good on paper, but the reality is that we were fortunate to finish the race. Reliability caused us real concern and it is something we are working on as our highest priority.
"In a shorter season with a yet to be determined number of races, every point counts, so we need to improve quickly on that front.
"Our main problems were with the electrical components of the gearbox, caused by the aggressive kerbs in Spielberg.
"We first noticed the issue on Friday and immediately started working on mitigations for the next races, both at the factory and at the track. We will run new components this weekend to improve the situation."
