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.
"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."
