Toro Rosso technical director James Key will remain at the Italian squad for the foreseeable future after extending his contract with the team.
The Briton joined STR in 2012 from Sauber and has been a major figure in Toro Rosso increasing its technical staff.
It is not known how long the extension (announced on Tuesday) is for.
Speaking about the new contract Key said:
“I am delighted to continue with Toro Rosso and remain part of the Red Bull family,” “This is a team which I have great respect for and have thoroughly enjoyed working with for the past five years; now I look forwards to continuing our project into the future.
“This is a team which I have great respect for and have thoroughly enjoyed working with for the past five years; now I look forward to continuing our project into the future.
“I would like to thank Franz Tost and Red Bull for their continued support and confidence. We have more work to do, and I look forwards to taking the next steps with Toro Rosso towards our goals”
Toro Rosso team principal Franz Tost added:
“Formula 1 is a team sport, but one in which an individual can still make a difference,”
“So far, in his time with us, James has proved that he can indeed make that difference, leading the technical side of the operation.
“Not only has he been adept at producing chassis-aero packages that are well regarded throughout the paddock, he has also shown the management skills necessary to get the most out of all the various departments that work together both here in Faenza and in Bicester.
“I am therefore delighted that James will be with us for the foreseeable future to continue this fruitful process.”
