Spyker will be using Ferrari engines next year

Spyker, who have taken over the Midland team, have said the 23-year-old has signed a long-term deal.

Sutil, the 2006 Japanese Formula Three championship winner, was test driver for Midland at three races this year and replaces Tiago Monteiro.

"I really enjoyed being in the F1 paddock and I thought I would be a test driver in 2007," he said.

Midland failed to score a point this year but the Spyker F1 team are switching from Toyota to Ferrari engines for 2007.

"This is a great signing for the team but also a proud one for me personally," said team boss Colin Kolles.

"Adrian made his F3 Euroseries debut with Team Kolles in 2004 and quite obviously had huge potential when he scored his first pole position in his third race.

"He has driven for two great teams since then and matured very quickly.

"Everyone at Spyker was very impressed when he drove for us in 2006 which is why we have worked long and hard to get him in the race team."

Sutil is an accomplished pianist whose Uruguayan-born father Jorge played violin for the Munich Philarmonic.

Toro Rosso is now the only team yet to confirm their 2007 line-up, although they are likely to retain Italian Vitantonio Liuzzi and American Scott Speed.
