In the lowest-key 'launch' so far this winter, Red Bull on Friday unveiled the Adrian Newey-penned RB3 on a crisp morning at Circuit de Catalunya in Spain.

Without the fireworks of McLaren's event or even an auditorium within sight, mechanics for the Milton-Keynes based squad simply rolled the curvy car into the Barcelona pit lane shortly before 9am for photographers to snap.

With a lower and thinner nose and distinctly McLaren-esque curvy side pods, the car was later taken onto the circuit by Mark Webber, who has joined Red Bull from Williams to be veteran David Coulthard's new team-mate.

Also present at the launch were Newey and team boss Christian Horner, both wearing heavy winter jackets, and Renault's Rob White, representing the team's new engine partner.
