Christian Horner believes Red Bull is 0.5s off the battle between Mercedes and Ferrari but is confident the RB13 has the development potential to catch up.
Red Bull had a disappointing start to the season with home hero Daniel Ricciardo failing to make the start of the Australian Grand Prix due to a gearbox sensor issue and then retiring after 29 laps with a fuel cell problem. Max Verstappen scored 10 points with a drive to fifth behind Ferrari's Kimi Raikkonen, but it was clear from both qualifying and the race that Red Bull has work to do to catch the ultimate pace of Mercedes and race winners Ferrari.
