McLaren say Fernando Alonso will cope with the increased workload from racing in the World Endurance Championship this year.
Alonso has signed up to drive for Toyota in the 2018/19 WEC 'Super Season', with the only question mark over his involvement in the scheduled eight races being the 6 Hours of Fuji as that conflicts with the United States Grand Prix.
McLaren's chief engineering officer Matt Morris believes the Spaniard's enjoyment of the new challenge will prove beneficial to his performances in F1.
'He'll be absolutely fine,' Morris said. 'I think you get the most out of Fernando when he's happy and if he's happy doing these other things then I think we'll benefit from that, that's my opinion on it. I don't think he's going to be tired or anything like that. I think he's just going to be motivated and for me that's lap time in F1.'
And executive director Zak Brown insists Alonso's WEC schedule is not a distraction from his McLaren role.
'No, not at all,' he argued.
'Because I think what would he be doing on those weekends otherwise? He wouldn't be testing in a Formula 1 car, he wouldn't be here on our simulator. 'There's only so much he can do. We've got everything we need out of him on the Formula 1 front so these are weekends he would either be in a go-kart or golfing or whatever he wants to do, and so he's just going to be in a Toyota WEC car.
'He knows what he's getting into. He's unbelievably prepared. He went from the 24 Hours of Daytona and then went and did a simulator test with Toyota for however long he did in the car. He's back in action and I think he's a very special athlete who can do things that probably most of us around this table would get knackered, but I don't think he would do it if he didn't think he could do it at the highest level.'
