"So I think it will take time, but both Red Bull and Honda have the same targets and I'm sure they will manage to achieve what they want".
Toro Rosso finished ninth of 10 teams previous year with the Honda engine but Red Bull has sounded optimistic about the progress made by the Japanese manufacturer.
"I'm very excited to just get started with the engine", Verstappen said.
Red Bull exploited one of its two authorized filming days to check the systems on its first Honda-powered vehicle.
Red Bull have unveiled a striking new livery design on a vehicle they hope will fire them towards a first championship success in six years.
Red Bull, meanwhile, enters 2019 with a tweaked driver line-up, having drafted in long-term junior and 2018 Toro Rosso racer Pierre Gasly in place of Renault-bound Daniel Ricciardo. "The first time was in Super Formula, so I went to Japan a lot, spent time in the country to learn the culture, to learn the way they communicate, the way they work and it's really different than what we have in Europe so you really need to adapt yourself to the culture and understand how things work there if you want to extract the best from the people".
"What I'm most looking forward to is starting the season and seeing how the whole team is operating together with Honda and how the engine is performing together with the chassis", said Verstappen ahead of the initial limited mileage filming day.
"You get a first impression and you see if there any little issues with the vehicle or engine".
And on Wednesday, they gave us the first glimpse of the challenger - in a dramatic camouflage-style livery instead of the team's familiar racing colours - they hope can take the fight to Mercedes and Ferrari.
"I want to get the best out of myself, but you have to see what the vehicle and engine are going to do". I am optimistic, but also realistic and only time will tell as to how we will get on.
"Up until Australia you can't really set goals - it's a bit blind".
