Four-time constructor's champion Red Bull Racing and primary sponsor Infiniti have reached a mutual agreement to end their partnerships. As a result, Infiniti will no longer provide light vans to RBR for the team's pitwork and day to day activities. The agreement also ends the sponsorship one year earlier than the original contract.

Infiniti has been Red Bull Racing's official partner since the 2011 season. Apart from the four straight constructor's championships, the four year major sponsorship deal also yielded four consecutive driver's championship with Sebastian Vettel. All in all, with Infiniti as a major partner, Red Bull Racing scored 34 wins with Vettel, Mark Webber and Daniel Ricciardo.

With the contract over, Red Bull Racing has made a deal with Swiss watchmaker Tag Heuer. Tag Heuer will serve as the team's primary sponsor, as well as RBR's official timekeeper, watch and team performance partner. Engines for next season will still be provided by Renault but will now carry the Tag Heuer name. RBR's car for 2016 is officially named the Red Bull Racing-TAG Heuer RB12.
