Honda is confident it can achieve a step forward in both driveability and reliability at the Spanish Grand Prix.
McLaren-Honda has struggled in both areas this season, with Fernando Alonso and Jenson Button still without a point from the opening four races of 2015. Button failed to start the Bahrain Grand Prix after a weekend plagued with reliability issues but Honda chief Yasuhisa Arai is confident fixes have been found.
"The short break before the Spanish GP has been good for Honda, to calmly reflect on what has happened in the first four races, to analyse what we have done well or not so well, and to make preparations ahead of the European races," Arai said.
"We hope that Spain will see another incremental step forward for Honda, in which we've prepared updates on the power unit to help with driveability and reliability. And like us, McLaren has had a productive two weeks and will be bringing more updates to test at the track and we'll see how the car will run together as one."
Though it is yet to score a point, Honda has made progress at all four races this season and Arai is confident that can continue in Barcelona.
"We're confident that every step we take together as a team is in the right direction, and hopefully this weekend will once again prove our continuing progress."
