Tramontana Concept Car

The Tramontana is a Spanish single or twin seat sports car with styling inspired by open wheel racing cars and built in Girona on the Costa Brava (Catalonia) and costing from £400,000, 610.000€ or $660,000 and launched at the 2005 Geneva Motor Show.
It features a mid-mounted twin turbocharged, 720 bhp (537 kW), 5.5 Litre, double overhead cam, V12 engine, 6 speed gearbox and rear wheel drive giving a top speed of 186 mph (299 km/h) and a 0-60 mph time of less than 4 seconds. The body is made of aluminium and carbon fibre, the car weighs in at 950 kg (2094.4 pounds) and the suspension is by double wishbones all round. If the two seat option is chosen, the passenger sits behind and slightly higher than the driver. The bonnet badge is made of solid white gold.

Only 12 a year are planned to be made when production reaches full capacity in 2008. Three were
scheduled to be made in 2006.

@ Chassis, 100% carbon fiber
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, this 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
Engine 12 cylinder in V 60º biturbo with intercooler
Power Selector 550 Hp – 404 kW to 5.000 rpm
720 Hp – 529 kW to 5.750 rpm
Max. Torque 900Nm to 3.500 rpm
920Nm to 4.000 rpm
Weight / power 1,7 kg / Hp
Diameter of cylinder ∅82 mm Displacement 5.513 cc Compression 9:1
Turbo pressure 1.3 bar
Lubrication system Dry sump Fuel Unleaded 98 Octane
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.

Thanks to 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.
Two 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.

@ Tyres
Rear: 335/30R20” (Y)
Front: 245/35R20” (Y)

To put “shoes” to the Tramontana it has been determined an intermediate solution of standard tyres with asymmetric design with wide longitudinal channels and very hard radial silent block. Together with a low tread pattern, allows the Tramontana to avoid the drift of the tyre and facilitates a perfect performance in the cornering.
The running band is side divided in three distinctive elements to satisfy the most demanding
performance that the Tramontana requires.

@ Steering, very sport sensations
Rack and pinion steering system: 2.75 turns lock to lock.
Turning cicle: 11 metres.

The steering column with double cardan system is adjustable in reach and lift, permitting the
drivers to adapt the driving position according to their preferences. Also the a.d. Tramontana
engineers have modified the parameters of steering assistance to increase the sport feeling, fact
that added to the easy access to the cams on the gear change, situated behind the steering wheel,
facilitates the driver the execution of layout you need in any situation. All this contributes to
a better driving precision and permits to enjoy all the sports qualities of the model.

@ Brakes
4 carbon-ceramic ventilated discs.
Front: 380×34 mm 6 piston caliper
Rear: 380×34 mm 6 piston caliper

a.d. Tramontana has developed an ABS system that allows, by means of braking distributor, to
distribute between the front and the rear train the power of braking obtained by the discs of
Likewise, the rear and front brake discs are elaborated with carbon-ceramic that do not need of
high temperatures for their maximum efficacy of braking. It is referred to a material that

combines the most innovative aerospace technology with the know-how of the Formula 1, providing thus a purely sports performance and a high durability of the brakes. To the advantages of the carbon-ceramic it is important to add other benefits of great benefit for the performance of the Tramontana, like the weight reduction up to a 70%, the improvement of the friction coefficient or the high energy absorption capacity and the scarce possibility to suffer fatigue in the braking
The effectiveness is spectacular. Combining the lightness of the monocoque with the power of the
six pistons per disc on the 4 wheels it permits to minimize the braking distance to beyond
incredible limits.

@ Ensured safety
To get the best mark in the subject of security, the Tramontana has been submitted to a Crash Test
whose demands have followed the dictations of the official regulation of the FIA. The car, built
with a carbon fibre monocoque, has needed a software developed especially to be adapted to the
characteristics of the Tramontana. In this study all the pieces passed through a side, front and
rear crash test.

The Tramontana emphasizes for offering a double security. First, all the exterior pieces are
designed and distributed so that in case of impact they never get inside. On the other hand, the
chassis has been strength with a security arch that protects the passengers. Moreover, the
security of the Tramontana is guaranteed thanks to its private structure that combines an
undeformable central zone (cockpit) with other eight collision absorption zones.

@ 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

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.

@ Gear box and Transmission / Clutch
The Tramontana has a sequential six-speed gear box of high competition, developed exclusively for this model, with twin plate clutch in light aluminium, inside a duraluminum bellhouse.

Triple cone syncronisation for the 1st and 2nd gear

@ Seats
The Tramontana also surprises for its interior, where the sportsmanship and the comfort breathe in all the details.

The first thing that we notice when we get in a Tramontana is, without doubt, the seating position
in tandem, the same as in a fighter. In fact, in its development has collaborated, among others,
Manuel Brown, an engineer in the field of aeronautics, member of Euro Fighter design team in

As opposed to the normal position of the passengers, side by side, the tandem position of the
seats of the Tramontana has permitted to centre the weight in an excellent way. Technically, a
42-58 weight distribution has been designed, obtaining thus an entrance in curve with a stable
relation of 50-50.
On the other hand, the visibility of the Tramontana is superior to that of a conventional vehicle,
due to the privileged position of the driver. The position of the seats can be personalized for
each client.

Option A: Two passengers
Comfort: 1+1= 2 seats
Racing: 1+1= 2 backets

Option B: One passenger
Racing: 1 backet

Regarding the seats, the Tramontana disposes of some kind of competition backets
that completely wrap the body of the passenger, assuring a sport sensation in the vehicle. The
client will have the possibility to choose among different types of leather to personalize the
seats as well as the interior of the vehicle.
