Vettel to test for Red Bull this month

The German already has experience of the car, having been drafted in for a test at Barcelona in February when he stood in for the injured David Coulthard.

However, he will be given a two day run at Jerez on September 17 and 18 to get acclimatised to his new team and the Renault engine and electronics that he will use in 2009 before returning to Toro Rosso for the remainder of the season.

Vettel's future teammate Mark Webber says he is excited about the arrival of the German, who has received a lot of interest since his strong performance in Valencia.

"You talk about short memories in F1," said Webber. "He (Vettel) had how many first lap shunts at the start of the season. Two or three good races and here we are. That is the reality of it.

"It is good, really good, and he is a very experienced youngster. There are not many of them around. Red Bull finally have the fruits of their (young driver) programme, which is great for Red Bull Racing."

When asked if he was observing Vettel's performances closer now that he was going to be his future teammate, Webber said: "Not really. He will test the car in Jerez so it will be interesting to see how he goes there driving the same car, engine and electronics, that sort of stuff.

"But it (the real comparisons) will start in February next year. Next year is so different and I am concentrating on myself, we have enough things to do and I am trying to get as many points as I can before the end of the year."
