McLaren's Lando Norris says the Mercedes power-unit hasn't made that much of a difference to the MCL35M's performance hinting that the team's aero tokens could have been put to better use.
McLaren pulled off a coup when they signed a deal with Mercedes to become the team's third customer for the 2021 Formula 1 season. Their British driver Norris however, thinks the improvements to the car have been marginal.
"A lot of people expect a lot differences but there isn't that much," Norris told Sky Sports.
"We had to use a lot of our tokens just to put the Mercedes engine in the back of the car so yeah, not ideal."
Norris however praised the team's effort over the winter especially with respect to the team's innovative floor design.
"The guys and girls (at McLaren) have been working really hard on making improvements elsewhere," Norris continued.
"The floor everyone's been talking about, I didn't even know it was that special. And everyone was going on about how, how special it was, and how innovative and different it is to the rest of the teams.
"Throughout the whole year, we'll be continuing to push it and try and change it in and improve it. But at the same time, it's fairly similar (the car to last year's MCL35), which is a good thing.
"It's just that that small step forward, which we're hoping will make us a little bit more competitive, but I'm sure everyone else has taken a step forward too."
