Vettel joined the rebranded Racing Point team for the coming season, where he'll partner Lance Stroll.
Aside from its name, the operation is largely unchanged from that which helped Sergio Perez to victory in the Sakhir Grand Prix in 2020.
It has already been hinted that the car will be predominantly green, with imagery showing deep British Racing Green coloured team kit.
That follows on from a livery tease when the team announced its partnership with Cognizant.
On Monday, McLaren became the first team to release its 2021 car, before completing a shakedown test at Silverstone on Tuesday.
AlphaTauri is the next team scheduled to peel back the covers on its 2021 car with its launch on Friday.
