Red Bull has moved to plug the gap created by Mark Webber’s enforced absence by appointing Brendon Hartley as test driver.
New Zealander Hartley will appear alongside Sebastian Vettel and Sebastien Buemi at Spain’s Jerez circuit on December 15th.
Webber has had to abandon all hopes of testing until next year after breaking his leg in a cycling accident in Tasmania last week.
Commenting on Hartley’s appointment, Red Bull team boss Christian Horner said: "Brendon is one of several promising talents in the Red Bull Junior Team and an opportunity has arisen to allow him to get some time in a Formula One car."
Red Bull junior driver Hartley competed in the British F3 Championship this year for Carlin Motorsport, and has previously tested for Red Bull’s sister team Toro Rosso.
He notably finished third in the Macau round of the F3 Championship after starting at the tail end of the grid.
By competing in the Formula Three series, Hartley has been following in the footsteps of former Formula One drivers including Ayrton Senna and Sir Jackie Stewart.
