Christian Horner is confident Red Bull can out-develop its rivals in 2017 and says a comparison to 2016 shows why the team should not be worried about its current deficit to Ferrari and Mercedes.
Red Bull had a disappointing opening race in Australia, spending the weekend a long way behind the Ferrari and Mercedes battle out in front. Max Verstappen was over a second off Lewis Hamilton's pole position time and then finished the race fifth, 28 seconds behind race winner Sebastian Vettel.
Last year Red Bull finished the Melbourne opener 24 seconds off the lead and was a clear third in the pecking order, only to win the Spanish Grand Prix and overhaul Ferrari before the summer break.
