Zak Brown is refusing to set any definitive targets for McLaren but expects they will be “challenging towards the front” this season.
Having bid farewell to Honda after a disasterous three year relationship, McLaren will be powered by Renault in 2018.
The Renault engine is a proven race winner with Red Bull triumphant in three grands prix last season.
As such Brown says he believes McLaren will return to the sharp end of the grid when the 2018 season begins in Australia in March.
“We are one of the big teams, we need to get back to the front,” he told Sky Sports.
