Autosport revealed at the end of October that the Aston Martin name was likely to return to F1, after a two-year run in 1959-60.
Talks have continued in recent weeks about the details, which will likely see the team renamed to Aston Martin Racing, and run with a blue and gold livery as part of a link with sponsor Johnnie Walker.
Did not read anywhere before that Johnnie Walker will be their sponsor. So basically after Tag Heuer jumping to Red Bull, its Johnnie Walker which has moved to Force India or Aston Martin Racing
