The Spaniard, a winner in 2005 and 2006 raced for the Woking-based
constructor in 2007 and between 2015-2018 but will keep racing at the
Indianapolis 500 this year looking to secure motorsport’s Triple Crown
having already won a Monaco Grand Prix and a Le Mans 24.
"I said before I stopped racing in Formula 1 last year that I see
myself with McLaren for a long-time to come, so I am delighted at this
new role and the ability to stay closely involved with the team I feel
is my spiritual home" 37-year-old Alonso said in a statement.
"For any race team, having someone of Fernando's class on hand to
provide support through his experience is of huge value," McLaren's
chief executive Zak Brown said.
"His insights and perspective will be welcomed by both our drivers
and engineers alike, while his stature and character remain highly
appealing to our partners and fans," Brown added.
