McLaren racing director Eric Boullier says that there are no quick fixes for the problems facing the team.
That means McLaren is likely to struggle at the Australian Grand Prix in two weeks time. Ongoing electrical problems at pre-season testing have left them behind its rivals in terms of pace, reliability and mileage.
McLaren was hit by more problems in the final day of pre-season testing at the Circuit de Barcelona-Catalunya.
"Today was not the way we’d hoped to conclude the final day of pre-season testing," Boullier confirmed.
"Thursday’s electrical issues persisted, prompting us to make regular changes to the car throughout the day in order to identify what has been causing the car to lose power intermittently."
Boillier was able to find a slightly brighter side on which to look. "Although we’ve suffered a number of issues over the course of two weeks of testing, we’ve certainly learned a lot about the car.
"We know the problems that need to be addressed.
"Plainly speaking, they aren’t overnight fixes. But we’re hopeful both McLaren and Honda will be able to make progress on them ahead of Australia.
"The guys and girls in the team have worked tirelessly and relentlessly to keep moving us forward day-by-day. I’m incredibly proud and appreciative of the hard work and determination shown within the team.
"It’s not been an easy testing period for us by any stretch. But we’re as motivated as ever to turn it around and find the solutions we need to get us back on track and headed in the direction we need to go."
