During that time, McLaren's pace has transformed dramatically. In 2019, the team were very much a midfield outfit, and steadily since, they have progressed to where they are now - at the front of the grid and within touching distance of their first constructors' championship since 1998.
Remarkably, despite their dismal start to the season, McLaren were able to turn their 2023 season around with some incredible mid-season upgrades, and the team have not looked back since.
Despite not starting this season at the front of the grid, an early upgrade package soon put them alongside the very best cars in the sport, and ever since, anything they have bolted onto the car has seemed to work.
Naturally, the Brit sees this as justification for remaining loyal to the team over the years, signing multiple contract renewals even when their form was not the best and pundits were questioning his future with the team.
"I’m very happy that I've stuck with the team that I believed in even when a lot of people didn't," Norris explained to The Race.
"And for all of that to actually come true, when it was hard to believe at times, when we could take two steps forward and then step back, and then catch up and then drop back."
The McLaren star did confess, however, that there were times when doubts over his future with the team crossed his mind, admitting that he could have gone to different teams in the past, but that he is very glad he stuck it out.
"There were times when I did question it for sure, on what's the best for my future and what do I want to do," Norris added.
"The fact we've been able to go from where we were to beating Red Bull, when not even 12 months ago they had the most dominant season, that’s an incredible achievement.
"I'm happy that I stuck through the harder times when I could have picked an easier route out of it, could have gone to different teams.
"The team understand that too, the journey that we've been on together, and I think they appreciate that, which probably makes me the happiest out of all of it."
Although his drivers' championship bid looks set to fall short, Norris' loyalty looks as though it could pay off in terms of a constructors' championship, provided McLaren maintain their form over the last three rounds of the season.
