Honda's updated power unit will focus on providing better driveability and reliability at the Spanish Grand Prix this weekend.
The engine manufacturer has struggled in both areas since the start of the season, and as a result McLaren has yet to score a point in the opening four races. With Jenson Button failing to start the Bahrain Grand Prix, reliability is clearly an area of concern for Honda and chief officer of motorsport Yasuhisa Arai says fixes have been put in place which will be tested in Barcelona.
"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.
“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."
Arai has previously said Honda has yet to finalise a programme to use its available tokens to update its power unit.
