Christian Horner has admitted at the start of the season he feared Red Bull would struggle to crack the top five but having sealed second place in the F1 world constructors' championship he has heaped praise on the achievement.
The Red Bull team principal led his squad into 2016 with uncertainties surrounding its car and rebranded TAG-Heuer power units after a dismal 2015 which saw the team slip to fourth in the teams' standings behind Mercedes, Ferrari and Williams.
Despite struggling to take a consistent charge to Mercedes, Red Bull has leapfrogged ahead of Ferrari and Williams this season and are the only other team to reach the top step of the rostrum other than the German manufacturer with Max Verstappen winning on debut in Spain and Daniel Ricciardo leading home a 1-2 in Malaysia.
Horner feels Red Bull can be proud of its success this season after wrapping up the runner-up spot in the F1 world constructors' championship in Brazil.
“It represents an enormous achievement for the whole team,” Horner said. “We came into the year thinking, 'you know what, to get into the top five will be difficult'.
“But the guys have produced a great car. The people at Renault have done a good job with the engine over the winter. Our season has just grown stronger and stronger.
“To be sitting here having achieved 14 or so podiums, two grand prix victories, Max's first victory in Barcelona, Daniel with a one-two finish in Malaysia and to be ahead of Ferrari on points and the nearest competitor to Mercedes represents is extremely impressive season for the whole team.”
