For the second day in a row, a Formula 1 team has seen their car launch plans hit after a photo of the new McLaren emerged on Twitter.

The British team was completing a shakedown/ filming day with the MCL33 in Spain ahead of the official unveiling on Friday and has continually teased a return to the 'papaya' shade of orange via social media.

That has now been confirmed by the image which sees the covers being blown up as the car emerges from the back of a truck revealing the new livery underneath.

Though not all the car is visible, an interesting sidepod structure much different to those seen so far is and hints that McLaren could have gone radical with their latest design.

A change from Honda to Renault power for 2018 also means the MCL33 has a lot of hype to live upto with some predicting even a first race win since 2012 is possible.

All will be revealed tomorrow.
