Red Bull Racing will continue to be powered by Renault until the end of 2018 after extending its contract with the French manufacturer.
In an announcement ahead of Sunday’s Monaco Grand Prix, Red Bull confirmed that it would continue to work with Renault for the next two seasons.
As part of the deal, B-team Toro Rosso will once again get Renault power units from 2017, having switched to year-old Ferrari engines for this season.
Both teams will have the opportunity to rebadge the power units as they see fit, with Red Bull currently running with branding from watch company TAG Heuer.
“We are very pleased to partner with two such strong teams as Red Bull Racing and Scuderia Toro Rosso,” Renault Sport Racing president Jerome Stroll said.
“Having competitive partners demonstrates the confidence both have in the improved Renault power unit and in our organization as a whole.”
“We are delighted to extend our partnership which has proved very successful over time,” Red Bull team principal Christian Horner added.
“After the reconstruction that Renault has undertaken, clear progress has been made which has made it logical to continue with the TAG Heuer badged engine.”
The extension of the deal marks a drastic change in fortunes for the Red Bull-Renault relationship after it almost ended in 2015 due to shortcomings with the power unit.
Red Bull sought supply from Ferrari, Mercedes and Honda, but was unable to strike a deal, forcing it to stick with Renault for 2016. The TAG Heuer rebranding came as part of the compromise.
However, Renault has made significant progress with its power unit over the winter, allowing Max Verstappen to claim Red Bull’s first win since 2014 two weeks ago in Spain.
