The new turbocharged 1.6-liter V-6 engines to be introduced from 2014 will be incorporated into the framework of an enhanced collaboration.
Within the new agreement, a technical joint venture will be set up in which Red Bull Racing and Renault Sport F1 will collaborate to develop the new V-6 drivetrain, both for Red Bull Racing as well as other customer teams.
However, in the meantime, Renault Sport F1 will continue to supply V-8 engines and KERS electric motor generator units to Red Bull Racing for 2012 and 2013.
Importantly, the latest announcement also means that Infiniti, the luxury arm of the Renault-Nissan global alliance, will be able to continue its sponsorship of the Red Bull Racing without the fear of having to support a non-allied engine builder.
The Red Bull Racing-Renault collaboration started in 2007 and has since matured into one of the most successful chassis-engine partnerships. The crowning moment came last year with the Drivers' and Constructors' Championships. And it looks like the alliance is about to repeat that success all over again.
