Red Bull motorsport chief Helmut Marko says the team have “no excuses” as they bid to mount a title challenge in 2020.
Red Bull have failed to challenge Mercedes consistently since the era of hybrid engines started in 2014.
But progress by team and engine partner Honda has raised hopes Max Verstappen can take on Lewis Hamilton next year.
“We’re going into the new year better than ever and with a great concept. Now we finally have to deliver,” Marko said.
Marko, who was speaking on Red Bull’s Servus TV station, added that both Honda and Verstappen were in “top” condition for 2020 and said the team were two weeks ahead of their normal schedule.
