The Milton Keynes-based team has embarked on an ambitious programme to produce its own power unit from the start of the 2026 season.
It has combined forces with Ford and the work at its new facility is advanced, with around 350 staff already working on the future engine which has been on the dyno since last year.
While Red Bull acknowledges the supreme challenge of going up against manufacturers like Mercedes and Ferrari, it equally feels its state-of-the-art facilities are just what is needed to make a success of its venture.
Verstappen, who has kept a close eye on the development of the engine plans, says things are advancing quicker than hoped.
“It's a very interesting project for us,” he said. “For me, it's also very important to know what's going on, also for my future within the team. And it's all looking very promising.
“Of course, to go up against all these manufacturers is going to be very tough, but the signs are good. But now of course we have to try and deliver.
“I think we started at the right time, and we are ahead of schedule. But you know, in one way, 2026 is just around the corner. So, a lot of things still need to be done.
“I think we are on a good track, but of course we have to keep on pushing flat out to be able to deliver a very strong engine.”
