Red Bull unveiled the RB10, their challenger for the 2014 season, in the pit lane this morning at the Jerez Circuit, ahead of the first day of testing. RB10 is result of first interpretation of F1’s radical new technical regulations,and powered by the Renault Energy F1-2014. The French engine manufacturer pledged a conservative approach to the 2014 season, saying "some compromises" had to be accepted to guarantee reliability.

Red Bull enjoyed hard-fought success in recent years winning the last four Drivers’ and Constructors’ titles. Now the game changes and due to the new regulations, the RB10 has little in common with its predecessors. Like several rival teams, including sister outfit Toro Rosso, Adrian Newey's design team has gone for a nose with a narrow protruding section at the front. Sebastian Vettel will once again lead the team, but he will have a new partner, Daniel Ricciardo, who has spent the past two seasons with sister team Toro Rosso and replaced Mark Webber.

Speaking about the new technical regulations, Newey said: "The new engines are a big challenge. It's hugely complicated to install as a package. It's the biggest engine change, without doubt, since turbos disappeared in the late '80s. Obviously Renault are the main players there, it's just our job to install it in the neatest way we can."

On the subject of the aerodynamic changes for 2014, Newey added that the narrower front wing had moved the endplates "to about the worst possible place" in front of the wheels.He also described the new rules governing the noses of the cars as "a funny regulation"

"Noses are ugly and ungainly. Not many owners of these noses could really love them."
