Despite uncertainty over whether Andretti Cadillac will be allowed to join the championship as an 11th team or not, the American powerhouse team has pressed ahead with its plans and has built up a car to this year's specifications.
Andretti says the car will be in Toyota's Cologne wind tunnel next week as he continues to build up his team with a view to being on the grid in the 2025 season at the earliest.
"At the moment we are still shooting for 2025," Andretti told Sky Sports F1 at Austin's US Grand Prix.
"Our car is actually going to be in the wind tunnel next week, so we have a car already built up in 2023 spec. We are flat out and we are building a team, so at the moment it is ’25 but could be ’26, we’ll see."
Andretti's application to join the F1 grid was recently approved by the FIA, but its fate still faces uncertainty as F1's commercial rights holder FOM, which also has to approve the entry, is less enthused about Andretti's plans to join as an 11th expansion team.
ANALYSIS: Why Andretti F1 hopes are not over, even if FOM says no
FOM is looking out for the interests of F1's current 10 teams, most of which are offering fierce resistance to the idea of having to share the championship's revenue with an additional party.
