Red Bull principal Christian Horner revealed on Tuesday that his team’s new 2015 challenger, the Renault-powered RB11, had not yet been completed.
However, Horner said he was confident that the new machine for drivers Daniel Ricciardo and Daniil Kvyat would be ready by the start of the first Formula One preseason test on Sunday in Jerez de la Frontera, Spain.
“We’re flat out into car build at the moment,” Horner said to reporters at an indoor skiing media event. “But it’s been for sure the most impressive winter we’ve had as a team in terms of everything coming together. The car being produced in the shortest time ever, with the design (team) hitting all their deadlines and targets.”
Last preseason, the RB10 was plagued by reliability woes that primarily centered around the Renault power units. The situation improved over the season as Ricciardo went on to score three wins, but both team and engine manufacturer desperately want a better showing from the start in 2015.
