Fernando Alonso quit Formula 1 after the Abu Dhabi Grand Prix on Sunday following an emotional final weekend after 17 seasons in the sport.
Alonso, who will race in the Indy 500 in 2019, will continue the 2018-19 season with the Toyota Gazoo Racing Team in the World Endurance Championships, where he has three races remaining and is the favorite to win the title.
McLaren have spent half the year waving off their driver and their papaya orange auto is sporting a special livery in honour of Alonso this weekend.
"I'm tying up with Mercedes, I'm going to be their simulator driver which will be a new experience for me as well so I will keep in contact with Formula One and I will still be involved in this world", he said. Thankfully, though, there has been no sight of those ubiquitous Alonso facemasks. I'm shier than people think and I want it go by quickly.
Johnson, who spent time at the McLaren team headquarters during the week leading up to the swap, also revealed he is excited about jumping in a single-seater race auto.

"Right now, I am not thinking to come back. but I don't know how I will feel next year". But yeah, for 2020 maybe I feel the need to do a full calendar in something.
"Fernando is a true legend", Hamilton admitted post-race.
"I am very thankful to them for the nice gesture and it was nice to celebrate at the chequered flag". I think in a couple of days.
"So I have had no time yesterday evening and this morning, and I need a bit of time to myself and realise the magic weekend that I had". I tried to sit down and check my telephone and after 30 seconds someone from the team knocked on the door and I had to say hello to a new person! "It's been a privilege to race when he is racing", he said on Sunday.
