McLaren: What livery will they unveil on the new MCL33 for F1 2018?
Is more livery change afoot for McLaren at Friday's launch?
McLaren boss Zak Brown has promised F1 fans will see "biggest change" of any team in their look for 2018 - but what does that mean for their new car, the MCL33?
The challenger, the first in the team's 52-year history to be powered by Renault engines, is launched on Friday and the team have dropped repeated hints the car will feature the second change of livery in as many seasons - although this time of the more subtle variety.
Last year McLaren signalled a radical departure from their darker liveries of the previous two decades by going orange, a colour first associated with the team in the 1960s and 1970s. But some fans were left disappointed it wasn't the same papaya shade used previously - particularly when it then appeared on Fernando Alonso's Indy 500 car last May.
But whatever scheme is revealed for 2018, it will become the latest car to join McLaren's distinctive - and varied - livery hall of fame...
Image:McLaren first ran a white and green colour scheme in F1 in 1966 with founder Bruce McLaren at the wheel
Image:Bruce McLaren sports a red livery on his McLaren at Monaco in 1967
Image:1968 saw the introduction of orange - or, technically speaking, 1375 CVC Pantone! - thanks to influence from cars in the Can-Am sportscar series
Image:McLaren continued with orange into 1971, the last year until 2017 that their car would run predominantly in that colour
Image:Orange was then slowly phased out, with the Yardley-liveried cars of 1971 and 1972 mainly white
Image:Emerson Fittipaldi's arrival saw the red of white of Philip Morris Tobacco on the McLaren. The colour stuck...
Image:There was, however, a miniscule break from red and white at Estroril in 1986 when Keke Rosberg's car featured a gold livery
Image:But red and white became synonymous with McLaren during their golden title-winning years with Honda in the 1980s with Prost and Senna at the wheel
Image:It was all red and white until 1997 when West replaced Marlboro and silver replaced 20 years of tradition. The new look made a winning debut and titles would follow a year later
Image:The silver was given a chrome effect from 2006 in a livery redesign described as 'revolutionary' by the team. The first season proved winless, but the shimmering design stuck
Image:Shorn of a title sponsor, and in their final season with Mercedes engines, McLaren introduced a moodier grey and black combination when their 2014 car was launched and first tested...
Image:...although by the first race in Melbourne there was already a tweak, with black extended to the sidepods, making it look a little less like the Silver Arrows over at Mercedes
Image:A variation of a theme again for the start of 2015 for Honda's ill-fated return, although a dayglo red stripe around the nosecone added some much-needed colour
Image:But 2015 didn't start how it finished as a new 'graphite grey' colour scheme was brought in from the start of the European season as chrome was finally dropped. But it didn't improve the team's fortunes!
Image:And back to the future and back to orange for 2017. After 20 years of dark colour schemes, McLaren went radical with by far the brightest livery on the grid
What awaits for 2018 when the MCL33 is revealed on Friday?
