The Lamborghini V10 cylinder DOHC four valve V90 5 liter, 500 Hp, 510Nm, is the concept solution for the high performance Gallardo.

The Name

Ferruccio Lamborghini - born under the zodiac sign of Taurus - when he founded the famous super car company, that since bears his name, gave to it the symbol of the fighting bull.
Later, in the'60 decade, 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 exception , 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 one 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. The Gallardo breed was created in the XVIII century. It draws its name from Francisco Gallardo and his brothers - cattle breeder at (of the) Santa Maria (Cadiz) - who thanks to the good results obtained by their bulls' behaviour in the arena, reached a considerable prestige in the most important plazas de toros.

Although the Gallardo family is considered the creator of this fundamental race of fighting bulls, it has been established that its origins are older, as they can be attributed to the Brothers Cartujos of Jerez (Cadiz), who bred it from the collection of the so called "diezmos" which was a tax that all cattle breeders and farmers had to pay to the catholic Church. The payment was made by giving to the Church one of every ten calves the herd would be increased by.

Bernardo de Quiros, a Navarro priest with a farm in the Rota location (Cadiz), taking advantage of his ecclesiastic relationships, brought the cattle (cows and calves) from the Dominican brothers. Years later, the Gallardo brothers brought a large part of the breeding stock from him.

Francisco Gallardo, through a selection, succeeded in fixing the characters of the Gallardo race, that can be resumed as follows: good looking face, heavily built, with a majority of black or gray mantle. During the fight they were famous for being very courageous and to maintain their strength and aggressiveness till the last tercio, which all bullfights fans loved.

After Francisco Gallardo's death, his heirs sold the breeding stock in three lots, one of which ended in the hands of Juan Miura, great-grandfather of the current owners of this legendary bulls breeding ranch.

The Concept

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 choice 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 4.3m) 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
- aluminium space frame
- low centre gravity
- weight distribution 42% front, 58% rear
- two front mounted water radiators and one side mounted oil cooler
- wheelbase 2.50m, front track 1.622m, rear track 1.592m
- total length 4.300m, width 1.900m, height 1.165m

Particular 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 Engine

The Lamborghini V10 cylinder DOHC four valve V90 5 liter, 500 Hp, 510Nm, 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 and 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 optimised 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 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 510Nm is reached at 4500rpm, with 80% of this maximum already achieved at only 1500rpm; 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 aluminium.

In summary:

- timing system: DOHC chain driven, continuously Variable inlet and exhaust Valve Timing
- inlet system: Variable Geometry
- exhaust system: two separated banks with two "5 in 1" exhaust manifolds
- ignition system: individual coils directly mounted on each spark plug
- engine electronic management: Lamborghini LIE
- lubrication system: dry sump
- max power 500 hp (368Kw) at 7800 rpm
- max torque 510 Nm at 4500 rpm

The Electronics

The core of the Gallardo's electronic system is the new generation Lamborghini LIE engine management system based on the strong Lamborghini know-how in this field. This system is connected, through a sophisticated CAN BUS network to the Lamborghini vehicle computer GFA and to the e gear, ESP/ABS, Dashboard ECU's and the other satellite ECU's (doors modules, climate system, rear spoiler, comfort/infotainment). In order to improve the direct control of the main function and the driving safety, all main information and warnings are centralized in the instrument panel. A dedicated ECU controls the air bags operation.

The main functions are:


- torque model based
- throttle control with Drive by Wire system
- fuel injection (multipoint sequential) management and ignition (individual coils directly mounted on the spark plugs) management
- variable geometry intake system management
- variable valve timing management
- on board diagnostic system management
- emission control management
- "black box" recorder


- robotized gearbox shifting (e gear)
- full vehicle stability management (ESP), including traction control (ASR), ABS with electronic brake force distribution, front automatic brake differential (ABD)
- climate system management
- rear spoiler management
- air bags management
- instrument panel and comfort-infotainment management

The Transmission

The main feature is the permanent four-wheel drive transmission, based on the well-proven Lamborghini Viscous Traction system. Such a system, which at constant speed on homogenous adhesion roads presents a traction force distribution around 30% front, 70% rear, is conceived to be "self-regulating", without the necessity of electronic controls. Indeed, thanks to the chosen characteristics of the viscous coupling, an intrinsic regulating closed loop operates in all conditions, varying the traction force distributes variations and of the adherence conditions.

Thus, during acceleration (or during climbing) on high adherence roads, the distribution will change favouring the rear axle (more rear traction force percentage, e.g. 80%, corresponding to the increased weight on the rear axle).

However, if in these conditions the rear axle tends to lose adherence, more traction is immediately biased to the front, with the system tending to reach a point where the adhesion utilized by the two axles are identical.

The gearbox is 6 speed, using of the latest generation double and triple-cone synchronizers and optimised actuation linkage in order to achieve precision and velocity in shifting while ease of operation is guaranteed.

A robotized sequential gear shifting system, the Lamborghini e gear, has also been developed, maintaining the basic mechanical gearbox unchanged.

The main features of this system, available as an option, are:

- electronic control, interfaced via CAN bus to the engine control system and the ESP system
- actuation by paddles directly mounted on the steering column
- possibility to select different operating modes: normal, sport, automatic, low adherence
- very fast but smooth shifting, equal to or better than that which is achievable by a very good driver with a standard gearbox

The rear differential features a friction-type 45% limited slip, while the front differential slip limitation is controlled by the ABD (automatic brake differential) function of the ESP system.

The clutch is a reduced diameter double plate clutch. This is logical consequence of the Gallardo's engineering car concept definition, in order to keep the engine (and consequently the centre of gravity) as low as possible.

Space Frame and Body

Together with the perfect definition of suspension, weight distribution centre of gravity and aerodynamic characteristics, the achievement of high body stiffness is fundamental to obtain optimal car dynamics and driving enjoyment even on long trips.

For the Gallardo Lamborghini engineers have chosen to utilize the aluminium-extruded parts welded to aluminium cast joint elements. On this differentiated systems (rivets or screws or welding) depending on the function of the part.
Other external "hang-on" parts (such as the bumpers) are made of thermoplastic material and connected by bolts.

Such a solution has achieved a very good torsion stiffness (over 23000Nm/º), with an optimal stiffness/weight ratio and also with excellent energy-absorption capabilities during the crash tests.

The reduced space frame and body weight permit to achieve a total car "dry" weight of 1430 kgs (in spite of its 4WD).

Suspension and Brakes

The choice of double wishbones front and rear suspension system, true to Lamborghini engineering tradition and a must for high performance sports cars, has been confirmed also for the Gallardo.

The accurate definition of the geometry, if the characteristics of springs and stabilizing bars and the adoption of Koni "self adjusting" FSD dampers have been fundamental in achieving the desired handling, high speed stability and comfort performances/

Great attention was given to optimizing the Gallardo's dynamic behaviour in curves. In order to guarantee the best car controllability, the dynamics are slightly under steering at the beginning of the curve and neutral for all the rest of the curve. No wind-up effects (typical of some 4WD cars with viscous transmission) are detectable, even in sharp concerning.

The introduction of "antidive" and "antisquat" characteristics guarantees optimal car behaviour also during acceleration and braking.

The Pirelli Pzero tires (front 235/35 ZR19, rear 295/30 ZR19) guarantee optimal adherence characteristics in the various driving conditions.

As an option winter tires with the same dimensions have been developed and will be available next fall.

The choice of 19" wheels has permitted the installation of large diameter brake disks (front 365 mm, rear 335) together with Brembo 8-piston callipers in the front and 4-piston callipers in the rear.

Such a braking system, which also features a state of the art ABS/ESP system, guarantees excellent brake efficiency (deceleration over 1.1g on dry) and the absence of fading phenomenon also after extreme use. The full stability control system (ESP) has been conceived and calibrated in order to assist the driver in demanding conditions, while still allowing a true sports driving experience.

Passive Safety

The Gallardo well exceeds all the European and North America safety standards. Just for example, driver's and passenger's "dual stage" front airbags (complying also with future "out of position requirements"), side "head-thorax" airbags and doors anti-intrusion bars are standard in all versions.

The Performance

The high engine power and torque output permit a top speed of 309 km/h and high acceleration capabilities. The top speed is reached guaranteeing an excellent car stability and controllability.

Indeed, in addition to the optimization of the suspension characteristics, a must was the definition of the correct aerodynamic features, by concentrating not only on the reduction of the drag coefficient, but, even more important aerodynamic body refinements (e.g. front flap, flat bottom) and to the implementation of a rear spoiler, electronically controlled as a function of the vehicle speed.
