Formula One team champions Red Bull on Friday extended their successful engine-supply deal with Renault for five more years to 2016.
The previous agreement between the two was due to end in 2012.
Red Bull team chief Christian Horner said: "We're obviously thrilled to announce this significantly enhanced agreement with the Renault-Nissan Alliance, who we have enjoyed a close working relationship with since 2007.
"Renault Sport F1 has always been very straightforward to work with, which has been a contributing factor to the on-going success of the Red Bull Racing Renault partnership."
Jean-Francois Caubet, managing director of Renault Sport F1, said: "The V6 power units due to be introduced from 2014 represent a huge undertaking and to have the input, resources and in-house F1 car expertise of Red Bull Technology will help the team at Renault Sport F1 specify, design and develop a competitive unit."
Renault engines will also power the Renault team, Williams and Team Lotus in F1 next year.
