New Zealand's Brendon Hartley will make his F1 debut proper when he tests for Red Bull at Jerez next month.

The Austrian team is drafting in its regular test driver, and Toro Rosso hopeful, Sebastien Buemi and British F3 star Hartley to cover for Mark Webber in the final test of 2008.

Buemi will drive on all three days, while Hartley will drive on the opening day before Sebastian Vettel takes over for the rest of the week.

Hartley, who turned 19 just two weeks ago, will be completing a full F1 test outing for the first time. Earlier he took part in a shakedown of the Toro Rosso in Italy and also had a brief run in the Red Bull car at Silverstone before it was rushed to the Japanese Grand Prix as a replacement chassis for David Coulthard.

"Brendon is one of the shining lights in the junior team and an opportunity has arisen to allow him to get some time in a Formula 1 car," said Christian Horner.

Hartley finished third in this season's British F3 championship – taking five race wins - and capped his strong season with a fine recovery drive from 20th on the grid to third place in the prestigious Macau Grand Prix two weeks ago. Hartley also set a new lap record in the Macau race.
