Red Bull Racing have finally confirmed they will be powered by modified Renault engines next season, badged Tag Heuer.
The Swiss watch manufacturers make the switch from long-term partners McLaren, who lent their name to engines from 1984-87.
Red Bull will take delivery of 2016 Renault power units, but will team up with engine developers Ilmor to make their own technical adjustments for the season under the Tag Heuer banner.
Red Bull Racing team principal Christian Horner said: “Tag Heuer has been an icon in the world of F1 for many years and we’re delighted that they’ve chosen to continue their association with the sport by teaming up with us.
“Our shared values of innovation and a desire to stand out from the crowd make this one of the most exciting partnerships in F1.
“We are also pleased to see Renault confirm its long-term commitment to F1 and would like to thank them for their contribution to the team since 2007.
“Their technical partnership with Ilmor gives us confidence, and we look forward to the 2016 season.”
Daniel Ricciardo and Daniil Kvyat will remain in the cockpit in 2016.
