Formula One title contenders Red Bull unveiled their striking new RB6 for the coming season on Wednesday with driver Mark Webber describing the car as "a limousine".
Red Bull were second in the constructors' championship last year behind Brawn, who have morphed into Mercedes this season, with German driver Sebastian Vettel also second in the drivers' standings won by Jenson Button.
The RB6 has a sleek look with the nose particularly eye-catching and more pointed than previous years thanks to the design of Adrian Newey, who won plaudits for last year's car.
A new "shark-fin" engine cover also makes the RB6 stand out while a ban on refuelling during races this year means all cars are longer than before given the large fuel tanks.
"This car is a limousine," Webber joked at the early-morning launch at the Jerez track in Spain, where Formula One's second official test session of the season started on Wednesday.
