The 2019 Red Bull vehicle is the first to be made since the former world champions formed a partnership with new power providers Honda.

Gasly joins incumbent and five-time race victor Max Verstappen, under contract with Red Bull through 2020. "I really want to feel how it upshifts, downshifts, how the driveability is, how much power there is".
"With Honda, we're expecting a lot, we're all very positive but I think it also needs to take a little bit of time, it can not be from race one it will be ideal". Now we can go testing properly, we'll see what we can get out of that and we'll be able to understand the vehicle and the engine a bit better.
"At the moment I am of course very optimistic, but also realistic".
"I've had the chance to have spent two years with Honda already", Gasly said.More news: Cardi B deletes Instagram account hours after winning Grammy Award
"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 relationship I will have with the engineers. Time will tell how we're going to perform". Formula One is the pinnacle of motorsport.
