Lotus Racing has confirmed that it will use Red Bull Technology gearboxes and hydraulic systems from the 2011 season.
The news follows on from the announcement that the team has ended its relationship with Cosworth. Lotus had used Xtrac gearboxes and hydraulics during its debut season in 2010.
"The announcement that we have reached a multi-year agreement with Red Bull Technology for the supply of our gearboxes and hydraulics from 2011 is obviously a massive step forward for us, both in engineering terms, and as an expression of our ambitions for next year and for future championships," said technical chief Mike Gascoyne.
"The gearbox / hydraulics package obviously plays a critical role in the performance of the car, not just on track but in design and packaging terms, and this deal gives our design and aero teams a very exciting platform to work with.
"The removal of the double diffusers in 2011 will allow the whole grid to tighten up the rear bodywork and mechanical structures around the gearbox, and this supply deal will allow us to capitalise on that with our 2011 car. Exciting times lie ahead."
Lotus is expected to make two further announcements this week, one of them expected to be a new deal to use Renault engines from next season.
The move would mean Lotus would use the same engine/gearbox combination as Red Bull Racing.
"We are very pleased about Lotus Racing's decision to use Red Bull Technology gearboxes and hydraulic systems from 2011," added Red Bull Racing boss Christian Horner.
"The fact that Red Bull Technology has been chosen to be a supplier to another team despite its short history demonstrates how much we have achieved since our first season. We very much look forward to working with Lotus Racing from 2011 onwards."
