Jenson Button says McLaren will keep pushing even if this weekend's Spanish GP doesn't yield the gains they had hoped for.
McLaren have struggled in the opening four grands prix of the season, fighting just to finish in the points never mind on the podium.
The Woking outfit, though, is known for having the expertise and technical know-how to turn things around.
Thus McLaren have arrived at the Barcelona circuit with a raft of upgrades for their MP4-28.
But even if things don't work out as they had hoped, Button is confident his team will keep pushing.
"Some parts could work, some might not. Obviously we hope they all do," Button said.
"If you find some parts do work then you know which direction you need to keep working in.
"But whatever happens I don't think the guys will get down.
"We're very good at improving throughout a season, and if this weekend doesn't go to plan, we'll still keep pushing.
"We want to win races - this team has won many races in its history - and that hasn't changed now.
"We're still a team that fights for victories, and we're going to do everything we can to do that."
