By accident or by careful design a photo of the 2016 Red Bull Formula 1 challenger, sporting an all new livery was 'leaked' on Twitter shortly before the official 'skin' was made public during a function in London.
The 2015 car was used to show off the new look which features a prominent Red Bull logo on the side-pods, with Total boldly placed on both the rear and front wing end-plates and TAG-Heuer branding on the lower side of the engine cover.
The iconic 'prancing bull' logo features on the air intake cover and a smaller version on the nose-cone.
As expected Renault and Infiniti branding no longer appear on the new livery.
The unusual matte finish of the car contrasts to the highly polished and gleaming bodywork that has been the norm for F1 cars over the ages.
Daniel Ricciardo and Daniil Kvyat were on hand kitted out in their latest Puma race suits.
Team boss Christian Horner said, "We decided to go with something a bit more innovative, aggressive, that will stand out in the crowd and stand out in a few more drivers' mirrors. It looks right and things that tend to look right, go right."
The new Red Bull RB12 will break cover on Monday on day one of the first test at Circuit de Catalunya, in Spain.
