Toto Wolff says his Mercedes team have "no sense of entitlement" as they head into the first year of the new Formula 1 technical regulations.
The new rules could result in a very different pecking order in 2022 and, with Mercedes having won eight consecutive Constructors' Championships, Wolff said that their past successes are firmly in the rear view mirror as his team focus on the challenge ahead.
"The mindset of the team has always been the same over the last few years," Wolff said at the launch of the new Mercedes W13 on Friday.
"The point count goes back to zero. There is nothing from the previous years that will make you win the current championship.
"No credits to be taken, but also no sense of entitlement. Every year, we are sceptical about whether we've done a good enough job and that's the right mentality."
"Sweat and tears" have gone into the new Mercedes
Mercedes opted to hold a shakedown at Silverstone on Friday, meaning the real car was on hand for the season launch.
Looking at the first machine designed by the Brackley-based team for F1's new era, Wolff says he is thrilled to see the result of so much hard work.
"For me, the best moments every year is when you fire up for the first time, which happened very early with us in December," he commented.
"Then the second moment is when the car is actually being put together. I was in the race bays the last few days looking at this unbelievable machine.
"Seeing it completely with its bodywork on is very exciting. So much sweat and tears have gone into this car and now we just need to make it drive fast."
