Lando Norris believes McLaren will improve with the Mercedes Formula 1 power unit after ending their deal with Renault.
McLaren spent the last three seasons with Renault power units after splitting from Honda in 2017. The deal with Mercedes runs until 2024 and reunites the two parties, who previously worked together and enjoyed ample success from 1995 to 2014, which is music to the ears of the 21-year-old.
"I think all round, it's a better package," Norris told Autosport. "It's more power. Touch wood, it's more reliability. It's a slightly better-fitting package, so as just a whole, there's a lot of positives about it.
"I'm not into everything, so I'm sure there are maybe some negatives there, and we have a good relationship with Renault, so things are very smooth now and we know them, and there's going to be a lot of new things.
"There's going to be some things which are a bit trickier, but as a package, it should be much better, and that gives us good confidence it will take us that little bit further towards the top."
McLaren are expected to carryover much of the chassis from the MCL35 car to the MCL35M in 2021, and while Norris admitted to struggling with last year's car at times, he expects the continuity to unleash more performance this season.
"With the tricky car that we had and the struggles and the positives and negatives, there's still many things we need to work through," he added. "I guess the good thing with having bad things with the car or negatives is that you can try and work on them and try and turn them into positives, and it will make the car quicker. That's a good thing.
"We're working very closely with the factory and the aero department and things like that, and everyone in the factory to continue working hard and developing the car into next year."
