Christian Horner feels that Red Bull's resurgence in 2016 primes them for a strong start to 2017.
Last year Red Bull failed to record a win amid a public falling out with engine supplier Renault. This season, with those bridges mended, Red Bull returned to the winners circle and many are expecting them to be Mercedes' biggest threat next year.
"It’s remarkable," team boss Horner told F1i. "12 months ago we’d had a pretty horrible year and the prospects weren’t looking hugely encouraging.
"At different points there had been three different solutions going into the back of the car for this year,", "Horner added. "13 months ago they were installing a Honda into the back of it!
"It was a tough winter but everybody got their head down, focused on developing the car and produced a great chassis which was evident from very much the first test."
Horner was also hugely positive about the rules shake-up coming into force in 2017 which will see cars not only become much faster, but more difficult to drive.
"I think the exciting factor is that there is going to be a bit of a shake-up in 2017. The cars are going to look great, they’re going to test the drivers much more," he said. "I think the braver drivers are going to be more rewarded.
"It gives the opportunity to balance things up a bit in terms of will it still be the same two silver cars on the front row and on the top steps of the podium," he said.
"It gives it the opportunity to shake that up a little bit," Horner added. "Formula One is set for a great year."
