The 2018 world champions revealed their challenger to retain the championship today.
The launch marked the first time Hamilton himself had seen the W09 in one piece and the world champion hailed the car he hopes will carry him to a fifth world title as “a work of art”.
“This is the most exciting part of the year to this point – to see the whole car come together,” Hamilton said.
Lewis soon took the car to the track, after team mate Bottas had driven it to the launch, using one of Mercedes’s two filming days for the shakedown.
Lewis, who is yet to extend his contract with Mercedes, will be hoping the W09 can bring him a fifth world title.
In addition to chassis changes, Mercedes say they have made major upgrades to their power unit in response to the reduction in the number of power unit components that can be used by each driver this season.
This season is setting up to be a good one!
