Franz Tost has explained that AlphaTauri face bigger bills as they head into the new regulation cycle in 2022.
With sweeping changes across the board of the technical regulations for next season, the AlphaTauri team boss explained that the traditional arrangement the Red Bull junior team have with the senior team won't have the usual benefits to start off.
AlphaTauri usually buy previous season technology from Red Bull, permitted under the regulations, but aren't able to do so at the start of the new regulation cycle as that older technology simply won't exist yet.
"We will take over everything that the regulations allow from Red Bull Technologies," Tost told Auto Motor und Sport.
"That is the transmission, the complete rear axle and many parts of the front axle - maybe even the whole axle.
"The parts stay the same. The only thing that changes is that it will be a lot more expensive for us because we are sourcing new parts. Until now we have always adopted the one from the previous model."
Despite the widespread changes and this year's introduction of a budget cap, Tost doesn't believe that the pecking order of the big teams will change much as they slowly begin the process of shrinking down to reflect the new financial regulations.
"I believe that the top three teams will continue to set the tone in 2022," he said.
"Why? You can continue to draw on unlimited resources until June. This is a huge advantage in terms of manpower and know-how. I don't think that this will fill the gap. With the others, you will see how well they work and where you get out in terms of performance."
