(from Lamborghini) Ferruccio
Lamborghini - born under the zodiac sign of Taurus - when he founded the
famous super car company, that since then bears his name, gave to it the
symbol of the fighting bull. Later, when the Miura was introduced, he
named the car after a famous bull's race, and this practice became a
tradition for the House of the Bull. Honouring this tradition, the
Management of Automobili Lamborghini have decided to baptize their
latest model with the name of a fighting bull's breed: the Gallardo (pron.:
ga:yàrdo). Most people probably are not aware that the origins of the
fighting bull proceed from five main breeds, that is: Cabrera, Navarra,
Vasqueña, Vistahermosa and Gallardo. Today, ninety percent of the
fighting bull breeds proceed from Vistahermosa branch, with some
exceptions, such as the Miura race - that comes from the Navarro - which
is today the only breeding stock that maintains a pure origin. Another
exception is the breeding race of "Partido de Resina" - that was called
once of "Pablo Romero"-, that comes from the Gallardo race.
Historically, these bulls have enjoyed a well-deserved fame of being the
most beautiful specimen within the race.
Designed to redefine its segment as the best
high performance sports car and driving behaviour that fits its driver
in every situation. The Gallardo is the synthesis of a true sports car
that can be used on an every day basis. While matching these two
apparently conflicting objectives, the guideline for Lamborghini
engineers has been to fulfill the necessary comfort requirements without
any compromise in the performances expected of a true Lamborghini car.
The choices for engine, transmission, space frame and body, suspensions,
brakes and electronics are then all in line with such an objective. The
result is a compact (length 4.3 m) 2-seater high performance car
(maximum speed well over 300 km/h), that can be driven with pleasure
both on race tracks and on long distance journeys on country and city
roads.
The layout has been conceived to reach the high performance targets, on
the basis of the sports-oriented concept for which Lamborghini is well
known. The basic characteristics of such a layout are:- mid-rear mounted
engine, with the gearbox behind the engine - permanent four-wheel drive
system- independent double wishbone suspension system- aluminum space
frame- low centre gravity- weight distribution 42front, 58rear- two
front mounted water radiators and one side mounted oil cooler- wheelbase
2.560 m, front track 1.622 m, rear track 1.592 m- total length 4.300 m,
width 1.900 m, height 1.165Particular attention was paid to achieve the
correct weight distribution, true to Lamborghini's engineering
tradition. In fact, the chosen weight distribution is the optimal for a
sports car, with advantages for traction, braking and handling. The
lowering of the centre of gravity has also been a fundamental guideline,
which also lead to the engineering decisions for engine and transmission
layout.
The Gallardo design vision was initiated in the year 2000. The
challenging and simultaneously fascinating task of our designers was to
cultivate the attributes from Lamborghini and combine them in an
extremely individual packaging. Its design, based on an
Italdesign-Giugiaro style proposal was developed by the Lamborghini
Centro Stile to incorporate the parameters of our extreme design
philosophy. The Gallardo dimensions combined with the competitive
performance targets ensure the car an athletic compactness. The long
wheelbase complemented by short overhangs dynamise its appearance. It
was clad in the typical and unique mono volume proportioning, our
heritage initiated by the Countach and integrates the Lamborghini design
attributes of purism, athleticism and sharpness. The cab-forward cockpit
integrated in the body by a strongly slanted front screen and tensed
pillars, the complex surfacing intersected by crisp graphics and its
cooling flow oriented detailing evokes as in the Lamborghini tradition
in its proportions and formal language a strong aeronautical influence.
Starring blade like front light graphics, the front face is orchestrated
around the dominant cooling inlets. The scissor door cinematic has been
reserved as traditional to the 12-cylinder lineage. The foldable side
mirrors slanted forward dynamising the side view are mounted on an
evolutive shoulder incorporating air inlets. The flush integration of
the door handles emphasize the lateral air intakes and like all details
improves the aerodynamic efficiency. The rear lights prolonging the
lines of the upper air intakes develop an aerodynamic lip present also
on the rotating spoiler, combining once again function and emotion. The
wheels, a strong differencing factor in the Lamborghini history develop
the traditional round holes design theme interacting them with spokes.
From the very beginning and in coherence with the defined layout, the
design phase was completely integrated in the project development. Thus,
a complete matching between style requirements and functional
requirements has been reached, avoiding style elements without
functional basis or functional parts with poor visual appearance.
The Lamborghini V10 cylinder DOHC four valve V90 5 liter, 500 Hp, 510
Nm, is the concept solution for the high performance Gallardo. Instead
of the more classical choice of a V72, an angle of 90 degrees was
preferred in order to limit the height of the engine with advantages in
the car layout (e.g. lower engine bonnet and better rear view) and in
the lowering of the centre of gravity (i.e. better car dynamic
characteristics). Even firing intervals (that ensure the smoothness of
the engine) are guaranteed by the adoption of crankpins incorporating an
18-degree offset. A dry sump lubrication system not only achieves the
correct lubrication even in extreme dynamic conditions, but also permits
the centre of gravity to be lowered further. The torque output is
optimized in the full rpm range. In order to achieve such an objective,
the charge efficiency was increased at various speeds by a precise
utilization of gas dynamic effects that take place in the intake and
exhaust system. These effects are managed by the adoption of a variable
geometry intake manifold and of a continuously variable valve timing
system, both for intake and exhaust. While the variable geometry (which
can be defined as "variable length") guarantees the correct base gas
dynamic characteristics both at low rpm (long runners) and high rpm
(short runners), the variable valve timing system guarantees the most
suitable valve opening and closing moments for each rpm.
For instance, the intake valve closing moment is anticipated at low rpm
and retarded at high rpm in order to coincide with the positive peaks of
the pressure pulsations at the intake valves. Thus, the maximum torque
of 510 Nm is reached at 4500 rpm, with 80of this maximum already
achieved at only 1500 rpm; conversely, the maximum power is obtained at
a much higher speed, i.e. 7800 rpm. The throttle control is performed
via a Drive by Wire system, with two electronic throttle bodies. The
construction technology is obviously all aluminum.In summary:- concept:
