"I am very excited to get started as the off-season has been quite long", Verstappen said earlier. Also, the livery is very lovely, even though it's only for today.
Red Bull's RB15 is the successor to a RB14 auto which finished last season battling for victories, with Verstappen, who won twice in 2018, widely tipped to challenge multiple champions Lewis Hamilton and Sebastian Vettel.
"So our objective very much is to try and be more consistent across all of the circuits, and hopefully with more horsepower than we had a year ago will only help to lessen that gap". "I really want to feel how it upshifts, downshifts, how the drivability is, how much power there is. It was a very positive day so very happy about it".
A tumultuous relationship with Renault, that yielded success at the start but an increasing number of reliability issues towards the end, was brought to a close, with Red Bull opting for a bold new future with Honda, despite the Japanese manufacturer being fourth and last in the engine pecking order. I am optimistic, but also realistic and only time will tell as to how we will get on.
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 buzz really starts at the beginning of the year when you see the auto coming together".
"What is very important is the team and Honda are pushing really hard to improve the development".
"There are a lot of things you need to understand about them, and I had the chance to be there and be in the country to learn this, so for sure, I think on this side, this will help the relation I will have with the engineers".
Both teams also gave their cars a track debut with a shakedown session at Silverstone, which will host this year's British Grand Prix.
