Itis also set to undertake a new identity for next year despite beinglisted as ‘Scuderia AlphaTauri RB’ in the FIA’s entry list . Butamid its pledge to work closely with Red Bull, Brown has raisedquestions over the independence of AlphaTauri. “We have some bigconcerns over the alliance between AlphaTauri and Red Bull,” Browntold Motorsport.com. " I think that is something that needs to beaddressed in the future. “So, I still think the sport has a way togo to make sure that everyone is truly independent. “It is twoteams with common ownership, which you wouldn’t have in othersports. “[It could benefit Red Bull in] a lot of different ways.There is a reason why they are moving a lot of their people fromItaly.” Brown curious over Red Bull development Red Bull enjoyed ahighly dominant campaign that saw it win 21 out of the 22 races enroute to double championship success. While McLaren ended the yearin strong fashion after successfully developing its car during thecampaign, Red Bull’s ability to switch focus to its 2024 carearlier due to its advantage leaves it as the favourite for the newseason. “The million-dollar question that none of us know is howearly did they [Red Bull] turn off this year’s car? “We know we’veoutperformed the others in the development race, and we know we’veclosed the gap to Red Bull but what none of us know is: did RedBull stop, and we just caught up, or were they still developing?”
