To be known as Walkinshaw Andretti United from next year, team owner Walkinshaw is hoping the new organisation will be able to align itself with a manufacturer.
“No, that's not a long-term goal or plan (to run a Camaro),” said Walkinshaw.
“We've been pretty open and honest that, as it stands today, our ideal situation will be to continue running Holdens next year, but there will be a renewed focus from myself and Michael (Andretti) to go and search for a new manufacturer going forward.
“It's one of our key objectives, to start putting the search on and the feelers out for a new manufacturer.
“We've got some fantastic connections on the road car side of things with a dozen or so manufacturers and (we're) very, very close with them.
“Michael's got the same thing from the racing side in the US as well with international brands so, ideally, together we can go and put a big search out there and try and find someone.
“If we don't get anyone, it won't be for lack of trying, that's for sure.”
Last night's announcement of the Walkinshaw/Andretti Autosport/United Autosports alliance will see Walkinshaw and Andretti hold an equal partnership while Brown and United Autosport will become a minority shareholder.
