Lando Norris feels that 2021 has brought the biggest change yet in terms of his off-track performance as a McLaren team member.
The Briton has already put in some impressive drives in the first two races of the season, but he believes that he has particularly stepped up when working with the team now that he is in his third year with the Woking-based squad.
"I would say this year has probably been the year that I feel like I've stepped up a little bit," Norris told the In The Fast Lane podcast.
"Not in terms of just driving the car better or things like that, but more my off-track performance, helping the team, leading to some areas a little bit more and having a bit more responsibility.
"So yeah, I'd say year three has been the year where things feel a little different."
Norris believes that the transition between 2020 and 2021 has been greater than that from his rookie year in 2019 to 2020. He partly puts the change down to the arrival of new teammate Daniel Ricciardo, who replaced Carlos Sainz at McLaren this year.
"The bigger difference was probably more from last year to this year," Norris said in reference to his past development in F1.
"Just with me being the experienced guy in terms of time at McLaren, comparing to Daniel. Daniel's got the experience of being in Formula 1, but I've got the experience of being with McLaren.
"So I think that's where my responsibility has gone up a little bit. I can refer to a lot more things about the past few years with how the car's been, and in developing this year's car.
"But it goes both ways. We're both adding in different areas."
So far in 2021 Norris has outperformed Ricciardo, and earned the Driver Of The Day award for his drive to third place at the Emilia Romagna Grand Prix.
