Not even a week after securing the 2010 world championship, Sebastian Vettel is back at the wheel of his Red Bull in Abu Dhabi on Friday morning.

The German is among a multitude of his race driver colleagues testing Pirelli's development 2011 tyres at the Yas Marina circuit.

Also running on Friday for their respective teams are Felipe Massa, Nico Rosberg, Robert Kubica, Rubens Barrichello and others.

"We will begin to understand the characteristics of the new tyres and what they mean for the suspension and the aerodynamic design," Red Bull's technical boss Adrian Newey told O Estado de S.Paulo newspaper.

"In short, this data will be used to finalise the 2011 cars," added the Briton. "There will be surprises."

Each team has been supplied eight sets of medium and soft compound tyres in Abu Dhabi - four for Friday and four for Saturday - and a dedicated Pirelli engineer.

After Abu Dhabi, Pirelli will move to Bahrain in early December for more private testing.
