mechanicals-Giugiaro Quaranta
The structure of the prototype is made up of the carbon monocoque frame onto which aluminum and special steel parts are assembled, while the windscreen and roof are made of stratified glass with UVA filter.
The Italdesign Giugiaro Quaranta is fit with electronic four-wheel drive, divided in a small electric motor on the fore-carriage and the thermal engine/electric engine system located in a central rear position. This particular structure, which has seen Toyota's involvement in the electronic control management, has made it possible to develop the vehicle on a 2620-mm wheelbase, ideal for a midengined car.
The batteries which assist the electric motors are located between the engine compartment and the cockpit and are powered directly by the solar panels. The Italdesign Giugiaro Quaranta features a double fuel-tank, integrated in the supporting frame, with a total capacity of 60 liters, giving a mileage of up to 1000 km.
Dynamic asset is variable in two ride height positions: sporting and raised. Maximum ground clearance is 230 mm, an absolute record which means that the super sports-car can take any type of terrain in its stride.
The main technical aspect that distinguishes the mechanical design of the Quaranta is the weight balance and in particular the "weight centering": all the mechanical weight of the vehicle is contained between the two axles, including the mufflers which are positioned in front of the rear wheels. Only the radiator and a large overhanging luggage compartment, able to accommodate two golfbags, remain outside.
The front suspensions also represent a breakthrough: designed according to F1 cars, they are equipped with a central mono-shock echoing an idea already presented by Italdesign - Giugiaro on the 2004 Toyota Volta and on the 1997 Alfa Romeo Scighera. The linkage mechanism of the levers guarantees exceptional stability in any type of situation, simulating a "multilink" mechanism. The links have been designed and engineered entirely by ITALDESIGN GIUGUIARO: the "ovalized" down tubes are made of special steel and the uprights of Ergal.
The entire Quaranta project is an idea of Italdesign Giugiaro, constructed in accordance with the classical formula of the package of services furnished to automotive manufacturers.
Quaranta confirms the classic Italdesign - Giugiaro versatile service formula for car manufacturers. The competence and capability of designing a new car model considering style development, frame development, safety and ergonomics analyses and mechanics development, starting only from a given functioning engine.
The chassis, bodywork and layout of the Italdesign Giugiaro Quaranta prototype have been designed by the Engineering Division of Italdesign Giugiaro, while the mechanicals and electronics have been developed in cooperation with Toyota. The vehicle was entirely built at the Moncalieri facilities.
