Perhaps the most widely-anticipated launch of the 2013 F1 season will see the covers come off Red Bull Racing's title-defender in Milton Keynes today (Sunday).

Unwrapping the RB9 over the weekend gives the team a chance to entertain the media and guests before packing up and heading for Jerez de la Frontera, where the first test of pre-season kicks off on Tuesday (5 February). Red Bull becomes the sixth team to launch this year, with the remaining five all due to reveal their cars in Spanish pit-lanes over the next couple of weeks.

After claiming three back-to-back driver and constructor crowns, it might be expected that the RB9 feature a target on its back but, as usual, onlookers will be more interested in seeking out any subtle innovations that Adrian Newey may have come up with.

The Briton has said that he felt there was little room for development after RB8, giving the rest of the field hope in the final season of the current regulations, but no-one will be taking RBR lightly.

The team will be fielding an unchanged line-up of triple world champion Sebastian Vettel and Mark Webber, with little in the way of surprises expected at the launch following the re-signing of Sebastien Buemi as test and reserve driver.

The one change already confirmed is to the name of the team, which becomes Infiniti Red Bull Racing following an escalation in its relationship with the car manufacturer. Since the partnership's inception in 2011, it has already seen the recruitment of Vettel as Infiniti's 'global brand ambassador', the launch of the Infiniti FX Vettel Edition, and product development input from Vettel and Buemi for the all-new Infiniti Q50 premium sports saloon.
