A day before it debuts at Jerez, the Renault-powered RB8 will be revealed on Monday.
And the launch of Adrian Newey’s next creation has become even more eagerly anticipated after rival top teams Ferrari and McLaren unveiled their 2012 machines.
Like the Caterham and Force India, Ferrari’s car – the F2012 – has been derided for its ‘ugly’ nose.
The McLaren, however, has a sleek aerodynamic shape at the front.
Asked about the unattractive Ferrari solution, Red Bull’s Marko insisted: “We have something that looks a lot better.
“Our car is not as ugly as the Ferrari, but it’s also not like the McLaren, which doesn’t have a kink in the nose at all.
“Ours is just a bit smaller and more elegant (than the Ferrari solution),” the Austrian added.
Also yet to be seen is the 2012 Mercedes, with the German marque’s Norbert Haug promising: “The most beautiful car will be the one at the front.”
