Max Verstappen has confirmed expectations that Red Bull will touch down in Australia this week with several improvements for the 2017 car.
The energy drink-owned team had a low-profile winter, obviously behind Mercedes and Ferrari but amid suggestions that Adrian Newey was planning a 'miracle upgrade' for Melbourne.
Asked how the Melbourne-spec car will differ, Verstappen told De Telegraaf newspaper just before leaving for Australia: "I can't say.
"But it looks better and hopefully it will be faster."
However, the 19-year-old is not confident he will have a pole and race-winning car this weekend.
"Personally, I don't think we can challenge for the victories at this stage. But we can still improve a lot during the season and we have started already," said Verstappen.
He admits that the big winter surprise was Ferrari's form, even though he is not sure the Italian team can challenge Mercedes for the title.
"But we can see they have made a big step forward and they will certainly fight for victories," said the Dutchman.
As for Mercedes, Verstappen told his website verstappen.nl: "They will always be there. They have probably done a little sandbagging, as always."
Verstappen finished 2016 in fifth place in the drivers' standings.
