Scuderia Toro Rosso did not retain Jaime Alguersuari or Sébastien Buemi, instead choosing to replace them with Daniel Ricciardo and 2011 Formula Renault 3.5 Series runner-up Jean-Éric Vergne. Ricciardo had previously served as the team's test and reserve driver before being placed at HRT for the 2011 British Grand Prix, while Vergne had completed a limited testing schedule for the team in the second half of the season. Sébastien Buemi became Red Bull Racing's testing and reserve driver contested the 24 Hours of Le Mans with Toyota, driving a TS030 Hybrid. Alguersuari was offered a seat at HRT, but turned it down and instead joined tyre supplier Pirelli as their test driver, developing tyre compounds for use in racing alongside former Virgin Racing driver Lucas di Grassi.
