Jan.21 (GMM) Caterham's 2013 car will emerge on the first day of winter testing at Jerez.
"The first road car from our partnership with Renault is CT02, hence CT03. Simple!" Caterham said on Twitter.
It will be launched on 5 February, which is the opening day of the first official pre-season test in southern Spain.
"Caterham ... will commence its programme immediately after taking the wraps off its new car," the team added in a statement.
