Honda plans upgrades for next F1 test after tough start for McLaren
Honda will introduce a host of upgrades to its latest Formula 1 engine for the next test at Barcelona to solve the reliability problems that it suffered at Jerez this week
The Japanese manufacturer faced a spate of niggling issues with its new power unit in F1's first 2015 test, which included sensor problems, oil level issues and a fuel pump failure.
With the reliability dramas limiting Honda's running to 79 laps over four days, it is clear a step forward is needed ahead of the next test which begins on February 19.
Honda's motorsport chief Yasuhisa Arai has no doubts that the difficulties it has faced this week will be sorted so that its Barcelona-spec engine will run better.
"There are many difficulties that we had this week, but we will fix it before the next Barcelona test and get back to work again," he told AUTOSPORT.
"The new engine will be a step up, because we are taking things step-by-step. Some parts will be final [race] parts, but not all.
"There are several testing parts still, and we will take final confirmation on those just before Melbourne."
Arai said that he had still total faith that Honda and McLaren would be able to perform strongly this season, and said he was encouraged that the Jerez dramas were not caused by any major design fault.
"There was no major big trouble," he said. "Our package is very tight and skinny, but some points have been validated.
"It is a tight package, but we had no big trouble with it."
