Having struggled for qualifying pace, McLaren is poised to bring a significant aerodynamic upgrade to the event, though warns against it being a cure all solution.
“Obviously in Barcelona there is a new aero package coming but I think 95 percent of the paddock is bringing a new aero package to Barcelona so maybe the gap will remain as it is or we will recover it a little bit or just lose a little bit of ground, who knows?” ventured Fernando Alonso.
“I think it is up to us to make the package work and deliver to expectations and hopefully some others do not deliver. That is our hope.”
McLaren's racing director, Eric Boullier, shared Alonso's sentiments.
“We are bringing new parts to every weekend,” Boullier said.
“There is a new direction starting from Barcelona but you can't expect, like Fernando said, to jump everybody.
“Obviously everyone is bringing parts and packages especially at the opening races.
“Anyway, Monaco there will be another upgrade and Canada there will be another upgrade and so on so it is every race.”
Alonso has finished in the points in all four races this season, recording the team's best result with fifth place in Australia, while team-mate Stoffel Vandoorne has scored points on three occasions.
Neither driver has yet made an appearance in the final phase of qualifying in 2018.
McLaren currently sits fourth in the constructors' championship on 36 points, a single point ahead of Renault.
