- Lamborghini Aventador LP700-4, 2012
The Lamborghini Aventador LP700-4, Automobili Lamborghini is redefining the very pinnacle of the world super sports car market - brutal power, outstanding lightweight engineering and phenomenal handling precision are combined with peerless design and the very finest equipment to deliver an unparalleled driving experience. With the Aventador, Lamborghini is taking a big step into the future - and building on the glorious history of the brand with the next automotive legend. The first customers will take delivery of the new Lamborghini Aventador LP700-4 in late summer 2011.
The technology package of the Lamborghini Aventador LP700-4 is utterly unique. It is based on an innovative monocoque made from carbon-fiber that combines exceptional lightweight engineering with the highest levels of stiffness and safety. The new twelve-cylinder with 6.5 liters' displacement and 515 kW / 700 hp brings together the ultimate in high-revving pleasure with astonishing low-end torque. Thanks to a dry weight of only 1,575 kilograms (3,472 lb), which is extremely low for this class of vehicle, the weight-to-power ratio stands at only 2.25 kilograms per hp (4.96 lb/hp). Even the fantastic 0-100 km/h (0-62 mph) acceleration figure of just 2.9 seconds and the top speed of 350 km/h (217 mph) do not fully describe the Aventador's extreme performance. And yet, fuel consumption and CO2 emissions are down by around 20 percent compared with its predecessor, despite the considerable increase in power (+8%).
The ISR transmission is unique among road-going vehicles, guaranteeing the fastest shifting time (only 50 milliseconds) and a highly emotional shift feel, while the lightweight chassis with pushrod suspension delivers absolute handling precision and competition-level performance. The expressively-designed interior offers hi-tech features ranging from the TFT cockpit display with Drive Select Mode system. The Aventador will be built to the very highest quality standards in an all-new production facility in Sant'Agata Bolognese.
Aventador: the name of one of the most courageous of all bulls
According to its tradition, Lamborghini's new flagship bears the name of a bull - naturally, a particularly courageous specimen from the world of the Spanish Corrida. Aventador was the name of a bull that entered into battle in October 1993 at the Saragossa Arena, earning the "Trofeo de la Peña La Madroñera" for its outstanding courage.
A sculpture of extreme dynamics
For Lamborghini, design is always the beauty of aggressive power, the elegance of breathtaking dynamics. From the very first glance, the new Aventador is unmistakably a Lamborghini, clothed in the brand's characteristic and distinctive design language - with its extremely powerful proportions, its exact lines and precise surfaces, and with taut muscularity in every one of its details. The designers in the Centro Stile Lamborghini have carefully developed this design language to give the Lamborghini Aventador a significant new edge. It is an avantgarde work of art, an incredibly dynamic sculpture, from the sharply honed front end through the extremely low roofline to the distinctive rear diffuser. Every line has a clear function, every form is dictated by its need for speed, yet the overall look is nothing less than spectacular and breathtaking.
The doors open upward - of course
Truly impressive proportions come from an overall length of 4,78 meters (188.19 in.) matched with an impressive width of 2,26 meters (88.98 in.) including the exterior mirrors, and further accentuated by an extremely low height of just 1.136 mm (44.72 in.). It goes without saying that both doors of the carbon-fiber monocoque open upward - a feature that was first introduced in the now legendary Countach and then used for subsequent V12 models such as Diablo and Murciélago. However, the Aventador also evokes its immediate predecessor the Murciélago - electronically managed air intakes open depending on the outdoor temperature and the need for cooling air,ensuring maximum aerodynamic efficiency. And for those whishing to flaunt the heart of their Lamborghini, the optional transparent engine bonnet exhibits the twelve-cylinder engine like a technical work of art in a display case.
Exclusive and high-tech interior
The Aventador's spacious interior combines the fine exclusivity of premium materials and perfect Italian craftsmanship with state-of-the-art technology and generous equipment. The red switch cover on the broad center tunnel encloses the start button used to awaken the twelve-cylinder. The interior is dominated by a next-generation dashboard - as in a modern airplane, the instruments are presented on a TFT-LCD screen using innovative display concepts. A second screen is dedicated to the standard-fit multimedia and navigation system.
Carbon-fiber monocoque
The new Lamborghini flagship has a full monocoque. The entire occupant cell, with tub and roof, is one single physical component. This ensures extreme rigidity and thus outstanding driving precision, as well as an extremely high level of passive safety for the driver and his passenger. The entire monocoque weighs only 147.5 kilograms (325.18 lb).
The monocoque, together with the front and rear Aluminium frames, features an impressive combination of extreme torsional stiffness of 35,000 Newton meters per degree and weighs only 229.5 kilograms (505.9 lb).
Maximum revs, amazing sound
For the Lamborghini Aventador LP700-4, the engineers in Lamborghini's R&D Department have developed a completely new high-performance power unit - an extremely powerful and high-revving, but very compact power unit. At 235 kilograms (518 lb), it is also extremely lightweight. A V12 with 515 kW (700 hp) at 8,250 rpm sets a whole new benchmark, even in the world of super sports cars. The maximum torque output is 690 Newton meters (509 lb-ft) at 5,500 rpm. The extremely well-rounded torque curve, the bull-like pulling power in every situation, the spontaneous responsiveness and, last but not least, the finely modulated but always highly emotional acoustics are what make this engine a stunning power plant of the very highest order.
Innovative transmission for maximum performance
Engineers at Lamborghini have created the perfect mate for the new twelve-cylinder engine with the highly innovative ISR (Independent Shifting Rods) transmission. The development objective was clearly formulated - to build not only the fastest robotized gearbox, but also to create the world's most emotional gear shift. Compared with a dual-clutch transmission, not only is the ISR gearbox much lighter, it also has smaller dimensions than a conventional manual unit - both key elements in the field of lightweight engineering for super sports cars.
Refined and safe with all-wheel drive
This kind of extreme power must be delivered reliably to the road. The driver of the Lamborghini Aventador LP700-4 can depend fully on its permanent all-wheel drive - indicated by the 4 in the model designation. In the driveline, an electronically controlled Haldex coupling distributes the forces between front and rear. In a matter of milliseconds, this coupling adapts the force distribution to match the dynamic situation. A self-blocking rear differential together with a front differential electronically controlled by ESP make for even more dynamic handling. The Drive Select Mode System enables the driver to choose vehicle characteristics (engine, transmission, differential, steering and dynamic control) from three settings - Strada (road), Sport and Corsa (track) - to suit his individual preferences.
Pushrod suspension
Lamborghini has equipped its new V12 super sports car with 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-fiber ceramic brake system, this lightweight chassis represents a further aspect of the new flagship's unique technology concept.
Extensive assistance and safety systems
In the hands of its driver, the Lamborghini Aventador LP700-4 is a high-precision machine - spontaneous, direct and always reliable. The driver is also assisted by the latest electronic systems such as the incredibly sporty, adjustable ESP system. When it comes to passive safety, front, head-thorax and knee airbags play their part alongside the extremely stiff carbon-fiber cell.
A rich and wide-ranging individualization program
A Lamborghini should always fit perfectly with the style and preferences of its owner. To this end, the range of individualization options is virtually inexhaustible. There is a selection of 13 production paint colors to choose from, three of which are highly sophisticated matt tones. A choice of two-tone interiors are offered with the "Sportivo" and "Elegante" versions, while a premium audio system and reversing camera are among the many technology options. And of course, the "Ad Personam" individualization program knows no limits when it comes to colors and materials.
The Design
Every Lamborghini is an avantgarde work of art, a fast-moving technical sculpture. Every line, every detail of a super sports car from Sant'Agata is derived from its function - namely speed, dynamics, performance. Every Lamborghini is a purist's dream, reduced to its very essence.
With the new Aventador LP700-4, the designers at the Centro Stile Lamborghini in Sant'Agata Bolognese have taken this committed philosophy to a whole new level - its extreme, razor-sharp lines portray a precision that is without parallel in automotive design. And its clean, taut and expertly executed surfaces demonstrate the exceptional competence and depth of experience possessed by Lamborghini in carbon-fiber body shell design.
The surface of the roof has a new geometry that provides greater spaciousness for the passengers while at the same time giving relief to the lines of the front section. This also addresses the aim of obtaining a better aerodynamic coefficient, continuing Lamborghini's design philosophy of 'form follows function'.
The engine cover utilizes the same styling giving continuity to the concept.
Inspiration from aeronautics
For the further development of the Lamborghini design language, designers pulled their inspiration from another sphere dominated by speed and dynamics - from modern aeronautics, from the world's fastest and most agile aircraft. This gave rise to a design of maximum functionality and spectacular sharpness, an extremely precise and highly technical design language with a new kind of vitality. Powerfully defined lines and taut surfaces create a fascinating interplay of light and shade, endowing the car with tremendous visual movement. The limited edition Reventón - a work of automotive art - and the Sesto Elemento 'technology demonstrator' were forerunners of this philosophy: the Aventador is the first Lamborghini series production car embodying this vision.
The Aventador, of course, also follows the mid-engine concept, with the vehicle weight concentrated around the vertical axis to reduce inertia and optimize dynamics. With the legendary Countach, Lamborghini was a pioneer of mid-engine construction, its revolutionary concept bringing racing technology to the road. The design of the Lamborghini Aventador adds visual emphasis to the mid-engine layout, with a look that concentrates its power on the rear axle.
Aerodynamic efficiency is crucial
For such an extremely powerful automobile, the most crucial task of the body shell design is aerodynamic efficiency: the optimum airflow for absolute stability at all speeds and, at the same time, optimum cooling for the engine. On the Aventador, all aerodynamic elements are integrated into the body shell form, from the front spoiler to the rear diffuser. A key role is played by the flat, optimized underbody. The rear spoiler is deployable and controlled electronically. At rest, it lies flush with the rear of the vehicle; in operation, it has two positions - the approach angle of 4 degrees is optimized for high speed and assists directional stability at the very top end of the spectrum. The tilt of 11 degrees, on the other hand, delivers considerably greater downforce at mid-range speeds, helping to optimize handling and stability. The car uses dynamic parameters to calculate for itself the most appropriate tilt angle.
Impressive proportions, mighty air intakes
The first striking impression of the Lamborghini Aventador focuses on its proportions. At a length of 4.78 meters (188.19 in.), it is a truly impressive 2.26 meters (88.98 in.) wide including exterior mirrors, but only 1,136 meters (44.72 in.) high. The impression of width is further emphasized by the widely spaced air intakes and headlamp units.
The Aventador's incredibly low front takes on a distinct arrow form, with the Lamborghini bull insignia gracing both the point and the center line, which continues its path along the entire length of the vehicle. The air guides are powerfully profiled and further emphasized by their glossy, black frames. The bi-xenon headlamps are clustered with the LED units for daytime running lights and indicators beneath hexagonal casings. The daytime running light comes from LED light guides that wrap around the main headlamp in a Y form. Seven further LEDs provide the light source for the indicator.
Two strokes define the side line
The extremely long side view is dominated by the very low roofline and by two sweeping strokes - the first emphasizes the front wheel arch; the second, very sharply drawn line begins at the front wheel arch and runs like a tensed muscle along the entire side of the car and over the rear wheel. The deeply recessed door and the mighty sill bear further testimony to the determined functionality of the Lamborghini design. Ultimately, these forms serve only one purpose - to deliver the maximum volume of cooling air to the mighty V12 power plant. The large air intakes behind the upward-opening doors are also enclosed in black plastic frames and guarded by a fine mesh. The engine air intake is located on the roof pillar, behind the third side window. And when cooling requirements are particularly high, additional air channels open up on the rear wheel arches.
The rear end, too, is dominated by openings framed in black, where the hot air finds its exit. The entire rear end is highly three-dimensional in its design. The lower diffuser stands in powerful relief, while the substantial format of the hexagonal tail pipe symbolizes the concentrated potency of the engine. The rear lights in LED technology reiterate the triple Y motive already familiar from current Lamborghini models.
V12 as an object of technical beauty
Equally familiar is the transparent engine bonnet (option), which adds a particularly attractive dimension to the many emotional perspectives on the Aventador. The twelve-cylinder power unit, with its mighty black intake manifold, lies in all its technical glory beneath the three cover panels. It is framed by diagonal carbon-fiber struts and accompanied by the powerful dampers from the pushrod suspensions.
The design philosophy continues into the surprisingly roomy interior. The cockpit is upholstered entirely in fine leather and also takes on a subtle arrow form. The controls are logically grouped on the broad center console. Here, too, the inspiration derived from aviation is immediately apparent - as in modern aircraft, the instruments are presented on a TFT-LCD screen. At the center of the display is a large dial - at the touch of a button, the driver can choose whether he would rather see the road speed read-out or the engine speed. Further information ranging from fuel level to the output from the on-board computer is grouped in fields surrounding the large dial.
The operating system
The most important switch is hidden beneath a red switch cover - the start button, which instantly fires the high-performance engine into life.
A second, seven-inch TFT-LCD screen in the center console belongs to the integrated multimedia system. Beneath it is the familiar array of Lamborghini toggle switches for operating functions such as the electric windows or the front axle lifting system, as well as the controls for the air conditioning.
The Lamborghini Aventador LP700-4 offers a state-of-the-art and comprehensive lineup of electronic vehicle, entertainment and communication systems. These functions are operated in a clear and intuitive manner via the Human-Machine Interface (HMI) on the center console, featuring a large push/turn control and eight function keys.
The carbon-fiber monocoque of the Lamborghini Aventador
Lamborghini is heading into the future with a systematic lightweight design concept - the intensive application of carbon-fiber materials forms the key foundation for the extreme dynamics of the new Aventador LP700-4. The new flagship is based on a full monocoque construction made with these innovative materials - conceived and produced entirely by Automobili Lamborghini in Sant'Agata Bolognese.
The development sees Lamborghini once again demonstrate its worldwide leading expertise in carbon-fiber technology. The super sports car brand from Sant'Agata Bolognese is the only automaker to have fully mastered the extensive CFRP process across a range of technologies in-house - from 3D design, through simulation, test, production and validation using state-of-the-art industrial processes to the very highest quality standards. With the Aventador, Lamborghini is putting its innovative, in-house developed and patented technologies into series production for the first time.
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 offers 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 and technologies, 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 mould. Lamborghini has achieved a major breakthrough by further developing this method. Using the patented "RTM-Lambo" process, the final mould 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 mould 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.
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 new V12 power unit - the heart of the Lamborghini Aventador LP700-4
The twelve-cylinder is the king of the engine world and the true heart of the Lamborghini brand. The very first model created by Feruccio Lamborghini, the 350 GT, made its appearance in 1964 featuring a twelve-cylinder engine that was incredibly innovative for its day. 3.5 liter displacement and 320 hp were the vital statistics back then - they formed the basis for ongoing increases and further development over the decades that followed. Miura, Espada, Countach, Diablo and, finally, Murciélago are just a few of the super sports cars born in Sant'Agata. All of them were, and will continue to be, driven by V12 engines - and all have long since risen to the status of automotive legend.
Now the next milestone in this glorious history appears - engineers in the Lamborghini R&D Department have developed a completely new high-performance power unit. That it would be another twelve-cylinder was never in doubt - and not only because of the special magic conjured up by the number twelve. The only real choice for Lamborghini is a high-revving naturally aspirated engine - the deeply reflexive and exceptionally powerful reaction of the automobile to the tiniest movement of the driver's right foot is, of course, a key part of the whole fascination inspired by a super sports car. Ten cylinders are ideal in the displacement class around the five liter mark, as evidenced by the highly acclaimed Gallardo engine. For the 6.5 liter displacement targeted in this case, the perfect number is twelve. A lower number of cylinders would result in larger and heavier pistons and con-rods, which would have a negative impact on the engine's high-revving characteristics.
Starting with a clean sheet of paper
The specification for the development of the new twelve-cylinder, known internally as the L539, was written quickly - yet was highly demanding in its formulation. Naturally, it had to deliver more power and torque than its predecessor in the Murciélago, but it should also be smaller and lighter and enable a lower center of gravity. At the end of the day, low weight is just as important to the performance of a super sports car as high power output. Fuel consumption and gas emissions should also be reduced significantly.
So the R&D team started with a clean sheet of paper - metaphorically speaking, of course. Design and development in Sant'Agata is conducted using state-of-the-art systems and equipment. The outcome is a V12 with a classic cylinder bank angle of 60 degrees, and thus an amazingly compact power package - the power unit measures only 665 millimeters from top to bottom, including the intake system. Its width, including the exhaust manifold, is only 848 millimeters, while its length is a mere 784 millimeters. Its weight of 235 kilograms is also respectably low - each kilogram of engine weight corresponds to 3.0 HP maximum output.
