The car that Mercedes launched on Friday will be the car Lewis Hamilton and Valtteri Bottas race in Melbourne with just minor updates between now and then.
Mercedes took the covers off its 2020 challenger, the W11, at the Silverstone circuit on Friday.
But while it has often been noted that the car launched differs to that run in testing, which again is different to the one raced at the season-opening grand prix, Mercedes say this year it will be pretty much the same car.
“We will be more conventional this year,” tech chief James Allison told Autosport.
“We will still have upgrades for Melbourne that will come in the second week of testing, but the entire new car approach of 2019 won’t feature.
