McLaren CEO Zak Brown believes the new-look vehicle can usher in a new era for the team.
McLaren have released images of their new auto but the MCL33 will now be presented with a physical reveal of the MCL33 in Spain.
But of more significance when the auto hits the track will be its new Renault engine with the fallen superpowers under massive pressure to deliver a vast upgrade in performance in 2018 following their split from Honda.
"I think the last three years make a very united team, a very strong team, and we will see the first results this year".
The striking livery, on a vehicle with plenty of space for sponsors after the departure of some big names in recent years, revives the colour first used half a century ago by team founder Bruce McLaren.

Even Eliza Harmon/Trajectory (remember her?) was basically wearing a precursor to Jesse Quick's speedster costume. An upcoming episode of Season 4 of The Flash will see Iris West becoming a speedster for the very first time.
After jumping out of the vehicle following his filming run, Alonso was beaming as he spoke about the first run, hailing it as an important moment for the team after a long winter working on the new model.
"That said, I'm really looking forward to getting behind the wheel of a Formula 1 auto for the first time in three months". In fact, McLaren tells us its the first time in its 52-year history it has run a Renault engine.
"We never took the easy route or looked to shortcut a process or a solution; and the result is a vehicle that is neat and well-resolved".
"We are humble about the challenge ahead, but feel we've prepared well, have a solid package that we can build upon and exploit as the season progresses, and have two excellent drivers who will make the difference in races".
Executive director Zak Brown says success would be "racing and qualifying at the front, getting on the podium".
"And we definitely view 2018 as the year when McLaren will move closer to the front, fighting teams and drivers as we improve our fortunes".
