AlphaTauri boss Franz Tost has explained why the team are not able to use more from sister team Red Bull in their own car design.
The two squads had opposing fortunes in 2022, with the RB18 delivering both the Drivers' and Constructors' Championships in dominant fashion while AlphaTauri slipped backwards in the pecking order, ending the year in P9.
In an exclusive interview with RacingNews365.com, Tost was asked whether it would make sense for the team to have a more cooperative relationship with Red Bull, particularly given the fact that Aston Martin's 2022 challenger appeared more similar to the champions' than AlphaTauri's did.
"We do everything, regarding the cooperation with Red Bull, which is [allowed in] the regulations," Tost explained.
"We get from Red Bull a gearbox, rear suspension, parts from the front suspension, hydraulics."
How the relationship has changed
While AlphaTauri use the same wind tunnel as Red Bull, Tost admits that this has to be done in a strict way.
"The wind tunnel, we have to use separately," the Austrian said.
"We use the same wind tunnel, but we are in the wind tunnel on Saturday, Sunday and Monday, and Red Bull [are] in the wind tunnel Wednesday, Thursday, Friday or something like this.
"We are not allowed to share anything. As you know, when we started our project [in 2006], we got everything from Red Bull. This was the best situation, but this was [subsequently] forbidden by the regulations."

Why rivals resemble Red Bull
In terms of why rival teams are now able to resemble Red Bull's car more than AlphaTauri can, Tost commented: "The Aston Martin looks like the Red Bull because Aston Martin took half of the aerodynamic employees from Red Bull.
"Of course, they build the same car and paint it green. This is for us, unfortunately, not the case, because we cannot take away leading people from Red Bull Technology and bring [them] to AlphaTauri.
"So it's a question of money, because these people for sure are not cheap."
