- Tramontana Tramontana, 2007
The Chassis, 100% carbon fibre
It has never been seen in the automotive history a street sports car which resembles so much a Formula 1 like the Tramontana does. It is the first time in the sports car market that it has been incorporated a 100 % carbon fibre monocoque chassis inspired in the design of a Formula 1 and manufactured with the same criteria, guaranteeing a high protection for its passengers. Moreover, it introduces a new structural system that combines an indeformable central zone (cockpit) with a weight of 128kg with other 8 deformable zones calculated for the absorption of the impact energy. In fact, the results extracted of the Crash Test (according to the FIA regulation) confirm that the structural calculation guarantees the integrity of its passengers displacing the lateral components toward the outside. This shows the high impact resistance of the carbon fibre used in the vehicle.
On the other hand, the monocoque, especially developed for the Tramontana, contributes a lightness and maximum rigidity to the whole, factor that together with its suspension system, unique on its market of double wishbones with pushrod and a great length of arms, improves the dynamical aptitudes of the vehicle. All this elaborated with materials of last generation of aerospace technology like the steel to the cromolibdenium, magnesium and duraluminium. Without doubt in the Tramontana the efficiency of the geometry and the weight has been tested, obtaining as result an unequalled performance.
The structure of the monocoque carried out in carbon fibre offers a high torsion resistance, which makes the driver feel like going on a rail.
In the assembly process have been adopted handcraft techniques like the obsession by pre-impregnate and cured in autoclave to 120 ºC, that provides an exceptional finish level and makes the construction of light and strong pieces easier.
Engine, from the competition to the asphalt
Among the final solutions of the Tramontana, we find a new electronic system and a central gasoline engine V12 Biturbo capable to offer a power from 550 Hp to 720 Hp, selectable through a switch situated in the dashboard.
Associated to a 6-speed gearbox, specially developed for the Tramontana, this 12 cylinders propeller in V reaches the 720 Hp to 5.750rpm with a maximum pair torque of 920nm at 4.000rpm. The result, 345 km/h of top speed and 3,7 seconds to reach the 100 km/h from stopped departure.
The weight-power relation is elevated to the 1,7 Kg/Hp, significant data that allow us to discover the kind of sensations that this fantastic assembly of chassis and engine can offer us.
The development of the electronic switchboard is made to measure, in a craft process of more than 2000 hours, that includes full silver wiring and a power map capable to obtain the maximum performance of the engine. Moreover, for the first time in a street car, lifelong relays, fuses and protections have been replaced by a module with just one connector that has only one terminal that brings together all the functions of a conventional device. This innovative system has reduced the wiring, the complexities of the consoles of relays and the fuses, avoiding any electromechanical deterioration.
Car body, beauty and functionality
Without doubt, the design of the Tramontana combines the curves of a fighter with a narrow front and a wider rear of big dimensions and finished in first quality leather and wood imported of the classics of the Spanish automotive industry. This aesthetics remains totally clear thanks to the design of the hardtop, which covers and protects the passengers, and to the rear and front spoilers, in the form of an airplane wing, that assures a great beauty and an excellent support at the same time. In short, a perfect harmony between sensuality, fine materials and elegant lines, an authentic jewel for the collectors.
All the pieces of the Tramontana car body are also elaborated in carbon fibre, assuring the maximum lightness of the vehicle with a total weight of 1.250 kg.
The dynamic study carried out by a.d. Tramontana, the pieces that form part of the car body have been created by considering its functionality and the important vehicle performance.
The result is some compacted forms, an expressive front and a suggestive aerodynamic outline with a marked silhouette. Everything in the Tramontana transmits force, character, personality and, above all, sportsmanship, nevertheless the new model is a worthy heir of the sports tradition of the Formula 1.
Suspensions, balance between sportsmanship and comfort
One of the key items of the Tramontana is its system of suspensions of double wishbones with push-rod and its great length of arms, elaborated with a sort of steel of aeronautical and competition specifications of the latest generation.
2 special programs have been used for the development, which have permitted the static and dynamic simulation of the whole vehicle. Different defined adjustments in theoretical calculations have been projected and experienced on it in order to analyze the performance before proceeding to the validation and arriving this way to the definition of the suspensions rates. Finally, a.d. Tramontana has bet on a suspension system that provides a better control, driving comfort, smaller oscillation and better speed cornering, due to the distance between axes, identical to that of a Formula 1.
In the same way, the Tramontana has a system of double electronic height regulation especially developed for the Tramontana, which allows the driver to raise or to lower the height of the vehicle according to the driving needs. It has been looked for a balance between the performance of a street car (at 130mm) and a sports car (at 85mm) considering the different driving styles.
Aerodynamics, the exigency of the geometry
The engineers team from a.d.Tramontana has worked very hard to find the maximal exigency and perfection regarding the aerodynamic performance of the Tramontana, an aesthetical reasoning as similar as possible to a Formula 1.
The aerodynamic performance is though to great speed cornering and, at the same time, get a minimum air penetration coefficient Cx=0,4.
The air intakes and cooling of the motor they have been designed with the objective to minimize the friction of the air and to optimize the performance of the motor.
Moreover, the vehicle has a laminated sheet situated under the vehicle, that eliminates turbulences and improves the drag.
In the same way, the wishbones, designed in the form of drop of water, they help to minimize this coefficient. In fact, all the external elements that stand out from the vehicle are thought to obtain the minimum air resistance. This is the reason of the airplane wing profile of the wishbones.
The front spoilers offer a higher lift compared with the rear ones to avoid loss direction sensations. In this sense, there is an important work to obtain a ground effect thanks to the air flow that penetrates in the lower part of the vehicle. This generates a negative lift toward the ground, making driving to high speeds easier.
Finally, another remarkable factor, has been the study to situate the centre of gravity of the Tramontana as low as possible to increase the cornering speed.
