It's been a month since the initial onslaught of new F1 car debuts, and Red Bull Racing is running in the back of the pack with the unveiling of its new contender. Called the RB5, the latest Red Bull was revealed at the Jerez circuit in Spain, where Sebastian Vettel, newly promoted from the Toro Rosso B-squad, drove a few test laps before a gearbox problem sidelined him for the rest of the day. He'll be joining Mark Weber, who limped without crutches to the debut, fresh out of surgery to remove a titanium rod from his leg following his bike injury in Tasmania.
Like its engine supplier Renault, Red Bull has signed a new partnership with French oil company Total, which will supply fuel and lubricants to both teams this season. You can check out images of the new RB5, designed under the same new regs as the rest of the field – meaning a smaller rear wing, a bigger front one, regenerative braking system and slick tires at each corner – in the gallery below. But don't expect to see any rear shots, as Red Bull was careful to keep the rear diffuser, which has been a source of controversy for the Toyota and Williams teams – hidden from sight pending the FIA's ruling on the design. With Honda's fate still undecided, only Toro Rosso and Force India have yet to reveal their cars as we approach the season opener in Melbourne late next month.
