THE Grove-based AT&T Williams team today confirmed that German driver Nico Hülkenberg, 20, has been contracted as the team's official test driver for the 2008 season.

The team said Hülkenberg, who tested for the team last week in Jerez, made a positive impression and conducted himself with maturity over the two days and 425kms of development work.

Hülkenberg said: "The two days of Formula One testing with the AT&T Williams team last week in Jerez were the realisation of an ambition that has driven me ever since my first kart race back in 1997. When I actually got out on track in the FW29, it fulfilled every expectation and more.

"So to have represented myself sufficiently well to have been appointed as the team's official test driver is the most amazing news and for me, Christmas has come early."

In the past three seasons, the former German kart champion has contested the German Formula BMW Championship, German F3, A1 GP and the Formula Three Euroseries.

From the 68 starts he has made in these various championships, he has claimed 25 race wins and 14 poles, winning the Formula BMW ADAC title and helping the German national team to its A1 GP title in 2006/7 as a series rookie.

Hülkenberg has also performed strongly in a number of non-championship races including winning the Ultimate Masters of Formula 3 at Zolder. In 2008, he will again contest the Formula 3 Euroseries alongside his Formula One testing duties.

Sam Michael, Williams technical director said: "Nico has been through the rigours of our driver assessment programme culminating in his two day test in Jerez last week. Clearly he has shown demonstrable talent in the junior formulae, but it was important for us to see if he could make the step to Formula One. On the evidence we have so far, Nico is a quick and capable driver."
