Potential lift effects caused by the intake of air through the central slot, as highlighted by simulated aerodynamic tests in the virtual reality centre, were eliminated thanks to an aerodynamic solution named Y DuctÂ®. The air enters the central intake, flows along a "Y-shaped" path and emerges from the two apertures inserted in the upper part of the bonnet, thereby generating downforce.
This aerodynamic flow is maximised by the rear spoiler's lower wings that increase the downforce. The spoilers with overlapping wings that characterise the lower part of the car's design at the front and the rear alike are suspended and help create an additional aerodynamic load. The slots on the front and rear wheel arches not only highlight ZEROUNO' s rather aggressive looks but also help dissipate hot air.
The lights use Full LED technology and also perform an aerodynamic function since they are floating systems mounted inside the front and rear wings. The rear view highlights ZEROUNO's "extreme" character - and the "semi-naked" styling is particularly evident: the taut, angular outlines of the spoilers reveal the tyres and, in the middle, the two 80 cm wide laminar exhausts in titanium, which are designed to accelerate the out-flow of exhaust gases.
In order to achieve a light weight designers and engineers also joined forces inside the cockpit. Since this car has type-approval for driving on public roads - it is consequently equipped with front and side airbags. Italdesign emphasised the use of material and on-board systems ensuring high performance and low weight. The interior of the car is simultaneously essential yet elegant, in keeping with the exterior: carbon fibre dominates the overall styling. Door panels, dashboard and central tunnel are all made exclusively with this material. The digital cockpit houses all the car's main controls. Three small monitors in the middle of the dashboard, on the other hand, control all air conditioning functions.
The five lucky owners of ZEROUNO will be able to maximise the customisation of their cars so that each one will be truly unique. Over and above finishing the bodywork with a colour specifically developed for the client, including full carbon look, Italdesign has also developed several optional packages involving the exterior and inside the cockpit. The most extreme customisation is offered with the "Corsa" package, which boosts an accentuated aerodynamic layout dedicated to race track performance and is designed to ensure the performances and the handling of the car with special designed light weight side mirrors, carbon fibre monocoque seats frame, racing rear wing with central longitudinal fin, monodado rims and a dedicated sport, titanium made, muffler. The "Corsa" package will be for track use only.
Not only was the ZEROUNO' s front design inspired by the single-seater racing cars, the tyres too have a direct motorsport link. Italdesign chose Formula 1's exclusive tyre supplier, Pirelli, to equipe its first Automobili Speciali model. The engineers developed a dedicated version of the high-performing Pirelli tyres, the P Zero, in 245/30 R20 for the front and 305/30 R20 for the back. Featuring High Working Range tread compounds, able to guarantee maximum grip in all conditions, ZEROUNO 's dedicated tyres belong to the new line of coloured tyres, premiered in Geneva by Pirelli. The new Pirelli tyres will be available in four different colors: white, red, yellow and metallic grey.
The notion of tailormade and handmade, the attention to detail, the choice of the best materials possible, fired by a combination of vast knowledge, comprehensive expertise, sophisticated research and innovative drive are the key elements shared by the ZEROUNO and the Excalibur Spider.
Powered by hand-wound Flying Tourbillon Skeleton Calibre RD505SQ, the Excalibur Spider Italdesign Edition with its cutting-edge materials and world-class design is no exception to these values and a magnificent symbol of a fruitful partnership to come.
