Lamborghini makes no compromises in the engineering and construction of its new flagship's all-carbon fiber monocoque
- Monocoque forms a single shell in carbon fiber
- Built entirely in-house by Lamborghini with patented process
Lamborghini's Geneva motor show launch of its Murciélago replacement promises an extraordinary new technology-driven super sports car. One significant feature will be the extensive use of carbon fiber-reinforced polymer (CFRP) technology throughout the car, and in particular, in the entirely carbon fiber composite monocoque.
The cell of the future Lamborghini flagship super sports car is made entirely from carbon fiber and has been designed as a monocoque structure. The load-bearing structure of the vehicle is engineered as a “single shell” that functions physically as one component, thus taking full advantage of the extreme rigidity of CFRP. Formula 1 race cars have been built using CFRP monocoques for many years – and have proven their crash worthiness time and again. The same applies to road-going sports cars featuring monocoque technology – the carbon fiber occupant cell functions like an extremely safe roll cage.

Construction offer many advantages
Of course, the term “single shell” applies only in the descriptive sense – the new Lamborghini monocoque is made from a series of individual parts with specific functions, such as stiffening elements made from Braiding technology, that is one of the best technology to manage energy adsorption in case of crash. After the curing process, however, this structure functions as a single component – including the base section known as the tub and the complete roof.
The full monocoque solution offers advantages which other processes, like a tub where a metal roof structure is attached in a conventional manner, cannot realize. That's why Lamborghini made the no compromise choice of the full monocoque, which weighs only 147.5 kilograms (324.5 lbs).
Extremely rigid construction
Superior passive safety is only one benefit of the extreme rigidity of a full carbon fiber monocoque - very high torsional rigidity is another. The monocoque is connected at the front and rear with equally rigid aluminum sub-frames, on which the suspension, engine and transmission are mounted.
The entire body-in-white of the future V12 model weighs only 229.5 kilograms (505 lbs) and boasts phenomenal torsional rigidity of 35,000 Newton meters per degree of twist. This guarantees a superb feeling of solidity, but, more importantly, extremely exact wheel control with excellent steering precision and sensitive feedback. For the dedicated driver, both are essential for truly enticing driving pleasure. The new Lamborghini flagship responds to the most minute steering input with the stunning precision of a perfectly balanced race car.
Depending on the form, function and requirements of the individual elements, the Lamborghini development team selected from three main CFRP manufacturing methods within its technology tool kit. They differ not only in their production processes, but also in the type of carbon fiber and its weave and, most importantly, in the chemical composition of the synthetic resin used.
Resin Transfer Moulding (RTM): In this process the carbon fiber mats are preformed and impregnated with an exact amount of resin. Afterwards, they are cured under heat while the part is in the mold. Lamborghini has achieved a major breakthrough by further developmening this method. Using the patented “RTM-Lambo” process, the final mold is no longer a heavy, complex metal piece, but is made instead from lightweight carbon-fiber parts, thus making the manufacturing process faster, more flexible and more efficient.
An additional benefit of the RTM-Lambo process is the low injection pressure that doesn't require expensive equipment.

Prepreg – The carbon fiber mats used in this method, commonly known as prepreg, are pre-injected by the supplier with a thermosetting liquid resin and must be stored at a low temperature. The mats are then laminated in molds and cured under heat and pressure in an autoclave. Prepreg components are complex to make, but have an extremely high-quality surface finish (Class-A surface quality) and are therefore the preferred option for use in visible locations.
Braiding – These components are manufactured by using RTM technology. This carbon fiber weave technology is derived from the textile industry and used to make tubular components for special applications such as structural roof pillars and rocker panels. The woven components are made by diagonally interweaving the fiber in several layers.
The monocoque of the new V12 super sports car is constructed using these technologies applied in a series of special processes. One significant advancement Lamborghini realized is the ability to use already-assembled monocoque elements as the mold for the next step in the process. This makes for a considerable simplification of the manufacturing process compared with conventional methods.
Epoxy foam components are also used within the monocoque. They are placed in strategic points to increase the stiffness of the monocoque by working as spacers between the composite layers while also dampening noise and vibration. In addition, aluminum inserts are laminated into the front and rear surfaces to facilitate connection with the aluminum front and rear sub-frame elements.
Because of the complexity of the materials and process outlined above, Lamborghini decided to produce its new monocoque completely in-house, managing one strategic step in the production process.
Quality control is an absolutely crucial factor – every single monocoque is measured to exacting tolerances of only 0.1 millimeters, facilitating the extreme precision of the overall vehicle. Quality control starts with the purchase of the carbon fiber parts. Every delivery of carbon fiber is certified and the material is checked regularly for compliance with quality standards. Lamborghini worked together with its suppliers to develop a world-exclusive fiber and resin system for its RTM technology. Ultimately, these materials and processes constitute an important part of Lamborghini's worldwide leading expertise in the field.
Carbon composite materials - A key technology for tomorrow's high-performance automotive engineering
These materials made from CFRP combine the lowest possible weight with excellent material characteristics – they are very light, extremely rigid and exceptionally precise.
Furthermore, CFRP materials can also be formed into highly complex components with integrated functions. This reduces the number of individual parts when compared to traditional metal construction – thus enabling further weight reduction. Lighter cars have lower fuel consumption and fewer CO2 emissions. Most significantly, however, it improves the power-to-weight ratio – the deciding factor in the overall feel and performance of a sports car. A super sports car built using CFRP accelerates faster, has superior handling and better braking.

The most successful super sports car in Lamborghini's history captures the imagination with the brutal power of its 560 hp V10 engine, the absolute grip of its permanent all-wheel drive and the razor-sharp precision of its chassis. Every kilometer in the Lamborghini Gallardo is an intense experience of explosive dynamics and absolute control. Its breathtaking performance is indicated by the 3.7 seconds it takes to reach 100 km/h and its top speed of 325 km/h.
"With the Gallardo LP 560-4 Bicolore, Lamborghini demonstrates once again the extreme, uncompromising and unmistakably Italian nature of our brand. The super sports cars from Lamborghini combine volcanic energy with design that is as unique as it is stylish," says Stephan Winkelmann, President and CEO of Automobili Lamborghini.
Unique design DNA
The success of Lamborghini's unequalled design DNA lies in the beauty of highly-concentrated power and precise function. The Gallardo is the sheer essence of form with a purist approach, so the body shell is crisply sculpted and completely free from decoration. A timeless piece of design and an uncompromising driving machine – the Lamborghini Gallardo is both.
Even more extreme, thanks to a personalized appearance
With its new Bicolore model, Lamborghini is now setting a further design highlight in the ten-cylinder model series. The colored exterior finish matched with the black on the upper area of the body gives the Gallardo a new, more aggressive personality that looks even wider, even more extreme and innately adhered to the road.
From the window-line upwards (including pillars, roof, engine hood and rear spoiler), the vehicle is decorated in Noctis Black - a pastel black that contrasts perfectly with the lower area of the body, available in a choice of five colors: Giallo Midas, Arancio Borealis, Grigio Telesto, Bianco Monocerus and Blu Caelum.
The exterior appearance is enhanced by Skorpius aluminum-alloy rims with 15 thin spokes that are forged to minimize unsprung weight and are finished in titanium gray enamel. And, the air intakes and front spoiler have a high-gloss black finish, as does the upper section of the rear diffuser.

Top-quality and highly individual interior
The contrast between black and color is repeated in an understated, elegant manner in the interior of the Gallardo LP 560-4 Bicolore. The instrument panel, seats, door panels and other elements in the passenger compartment are upholstered in the finest "Nero Persus" leather, with a refined contrast provided by precise stitching that is colored to match the exterior paintwork: yellow, orange, blue and gray (also used on the Bianco Monocerus version).
The bezel of the e-gear transmission on the center console is in Nero Noctis, just like the upper area of the vehicle. Obviously, the interior is finished in the Lamborghini tradition using only the materials of the very highest quality, which are crafted with undisputed professionalism and fine Italian workmanship.
V10 like a work of art in a glass display
The complete range of standard equipment includes the fast e-gear automated transmission controlled by paddles on the steering column. A lifting system enables the front axle to be raised for safer travel onto ramps and over humps in the road, and the engine hood in tempered glass provides a stunning view of the heart of the vehicle: a 5.2 liter, 90° V-10 engine with stratified direct injection.
From a satellite navigation system to a rear-view camera, from a brake system with carbon-ceramic discs to heated power seats, a long list of optional equipment and accessories allows the vehicle to be adapted to the personal requirements of any client.
Unique success for a super sports car
Well over 10,000 Gallardos have left the production facility at company headquarters in Sant'Agata Bolognese – a unique success story in the world of super sports cars. The Bicolore Special Edition is particularly intended for the enthusiast who desires a supercar with an exclusive appearance and remarkable design. In any event, he or she will own a Lamborghini that is altogether distinguished by an extremely dynamic character, maximum driving excitement, yet an ability to be driven daily.

Individual characters in one model range
The Gallardo Bicolore completes Lamborghini's ten-cylinder model range, which is enjoying enormous resonance worldwide with its broad spectrum of individual characters. While the Gallardo LP 560-4 is already a highly trained, extreme athlete, the Gallardo LP 570-4 Superleggera takes the notion of thoroughbred high performance even further. Thanks to its extensive experience in carbon-fiber lightweight engineering, Lamborghini succeeded in reducing its weight by a further 70 kilograms. At 2.35 kilograms per hp, the power-to-weight ratio of the Superleggera is the best in its class, with breathtaking performance guaranteed.
The Gallardo LP 560-4 Spyder, on the other hand, offers a very different kind of extreme driving pleasure – every trip with the roof down is a journey with a hurricane, yet with maximum protection. This can only be bettered – in true Lamborghini style – by the Gallardo LP 570-4 Spyder Performante. Its purist carbon-fiber lightweight engineering, according to Lamborghini's tradition, adds an even sharper edge to the dynamics.

Murciélago successor introduces pushrod suspensions in series production for the first time -Geneva 2011
• New V12 super sports car with pushrod suspension for race-car precision
• Detailed lightweight engineering concept with double wishbone suspension and carbon ceramic brake system
• Unique ‘motorsport’ feel combined with long-distance comfort
The new Lamborghini V12 super sports car which will debut at the upcoming Geneva motorshow will feature an innovative and highly sophisticated suspension concept. The pushrod spring and damper concept was inspired by Formula 1 and tuned perfectly to meet the needs of a high-performance road-going vehicle. Together with aluminum double wishbone suspension and a carbon ceramic brake system, this lightweight chassis is another element of the unique technology concept in Lamborghini's new flagship model.

An extremely precise, indeed razor-sharp, driving feel accurately describes the soul of the newest and most powerful super sports car ever to bear the sign of the bull. This includes a steering system that can think its way through a bend adhering to the perfect line, a suspension that masters the ideal balance between race-car feel for the road and plenty of comfort for ramping up the miles, and lateral stability that ensures absolute safety even at the very highest speeds.
Pushrod suspension derived from motorsport
With its phenomenal engine output of 515 kW / 700 hp and its comparatively low vehicle weight, the new V12 super sports car from Lamborghini blasts its way to the very highest speeds. The most important characteristic of the new suspension is its design in line with the pushrod principle ? inspired by Formula 1. The spring/damper elements are not located on the wheel mounts, but connected inboard to the bodyshell structure. They are transversely positioned: under the windscreen in the front and close to the engine in the rear. Pushrods and relay levers / rockers transmit the forces from the wheel mounts to the spring/damper elements.
Responsive handling characteristics at all speeds
This solution offers a whole series of impressive benefits: due to the combination of the double wishbone and pushrod arrangement, wheel control and damper remain separate from each other. As a result, handling is more responsive and easier to manage at all speeds, while rigid connection to the chassis also improves the precise and spontaneous reaction of the springs and dampers. As a result, spring stiffness can be notched back a little ? comfort increases, while precision remains. On the front axle, the shock absorbers are equipped with a hydraulic lifting system, which enables the front end of the super sports car to be lifted by 40 millimeters at the touch of a button, simplifying its ability to negotiate minor obstacles.

Systematic lightweight engineering in aluminum and carbon fiber
Aluminum and carbon fiber are also the most important lightweight engineering materials on the chassis. The entire suspension system, including upper and lower control arms, wheel mounts and relay levers are made from forged aluminum alloy. The large-diameter discs on the high-performance brake system, on the other hand, are made from lightweight and extremely hard-wearing carbon ceramic composite material. On the front axle, the ventilated discs measure no less than 400 millimeters in diameter, with braking force delivered via six cylinder calipers. On the rear axle, 380 millimeter diameter discs are used in combination with four cylinder calipers. The parking brake on the new Lamborghini top model is electrically powered.
Steering forms the sensitive connection between driver and automobile
The hydraulic steering on the Lamborghini V12 forms the highly sensitive connection between the driver and the super sports car, which runs on 19-inch wheels clad on 255/35 tires at the front and 20-inch rims on 335/30 tires at the rear. Steering Gear foresees 3 different servotronic characteristics managed by drive select mode. After all, not every day is the same and the "corsa" (race track) setting can perhaps sometimes be a little too demanding. |
