Red Bull Racing unveiled their Renault-powered RB7 at Valencia on Tuesday, the car they hope will see them retain the World titles.
Red Bull rose to the top of the Formula One ranks last season as the team claimed the Constructors' Championship ahead of McLaren while Sebastian Vettel pipped Fernando Alonso to the Drivers' Championship title.
Vettel, who became the youngest ever F1 World Champion, also became the fifth driver to wear the crown in five years.
However, Red Bull are intent on the German becoming the first since Alonso in 2006 to retain it.
The team launched their RB7 on Tuesday morning, with several notable changes to its predecessor.
The car features a higher nose and engine cover as well as a different rear wing design.
Red Bull design guru Adrian Newey told the official F1 website: "Preparing for the new season has been an interesting challenge for all of us.
"There have been a number of changes to the regulations and while they are not as comprehensive as the changes for 2009, the major differences - such as the re-introduction of the KERS system and the arrival of a moveable rear wing to aid overtaking - have meant that RB7 is quite different to last year's car.
"However, what we have done is taken the philosophy of continuing evolution. We have evolved RB6, which itself was an evolution of 2009's RB5, and this is, if you like, the third generation of a successful lineage."
