Lamborghini has unveiled the Reventón Roadster, defined as the most extreme sportscar in history of the brand. Like its coupé counterpart its design is inspired by the world of aviation. It will go on sale in October 2009 with a price of 1.1 Million Euros.

At the 2009 Frankfurt Motor Show Lamborghini has presented the Reventón Roadster, the open-top version of the Reventón, first introduced at Frankfurt in 2007. Powered by a 6.5 litre twelve-cylinder with 493 kW (670 PS), the Roadster sprints from 0 to 100 km/h (0 to 62 mph) in 3.4 seconds and reaches a top speed of 330 km/h (205 mph).
The open-top Reventón will be produced in less than 20 units that will be sold for 1.1 Million Euro (without taxes). Deliveries will begin October 2009.
Design

The Reventón Roadster is derived from the same creative thinking as the Coupé. Its designers found their inspiration in aviation – the aggressive wedge shape evokes images of fighter jets.


Styling cues include the powerful arrowhead form at the front, the mighty air intakes pulled way forward, the broad side skirts, the upwards opening scissor doors and the rear end with its menacing edges. Details set stylish accents, such as headlamps featuring bi-xenon units with LEDs forming the daytime running lights and indicators. The rear lamps are also equipped with LEDs.
Like the Coupé, the Reventón Roadster measures 4700 mm (185 in.) long.
It has a wheelbase of 2665 mm (105 in.) and is 2058 mm (81 in.) wide and 1132 mm (45 in.) high. The driver and passenger seating positions are low and sporty, separated by a substantial central tunnel.
Behind the two seats are two hidden pop-up bars that deploy upwards in just a few hundredths of a second in the event of an imminent rollover.



A fixed, horizontal wing-shaped member behind the seats bears the third brake light. The design of the Roadster’s long back is also quite distinct from that of the Coupé. The engine hood is virtually horizontal and a total of four windows made from glass provide a view of the mighty V12 in all its technical elegance.
Body Structure

The base bodyshell of the Reventón is already so stiff that the Roadster requires only minimal reinforcement. It has a dry weight of only 1690 kg (3,725 lbs.), just 25 kg, (55 lbs.) more than the Coupé.
Like the Coupé, the cell of the Roadster is made from high-strength steel profile and carbon components joined with specialist adhesive and rivets. The bodyshell is made almost entirely from carbon fibre elements, with sheet steel used only for the outer door skins.
Grey paintwork

A unique paint finish completes the razor sharp design language of the Lamborghini Reventón Roadster. For this special edition, designers have created a new shade of matt grey called Reventón Grey.
As for the Reventón Coupé, which is a slightly different shade of grey, this is a matte paint finish that, in the sunlight, displays an unexpected impression of depth thanks to its special metal particles.
The wheels of the Reventón Roadster also incorporate the interplay of matt and glossy elements. The five spokes of the rims each bear a Y-form, and on each spoke are mounted small crescent-shaped wings made from matte carbon. These provide not only an unusual visual impact, but also a turbine effect that further improves cooling of the mighty ceramic brake discs.
Interior

The cockpit is structured with technical clarity, the interfaces arranged for functionality. Like a modern aircraft, the open two-seater no longer has classic analogue instrumentation – instead, information is delivered via two transreflective and one transmissive liquid-crystal displays. The driver can switch between two modes at the touch of a button – one digital view with illuminated bars and one level with classic round dials, albeit with changing colour graphics.
Centrally located at the top of the display is the G-force meter. It represents the intensity of the forces acting on the Reventón Roadster under acceleration, braking and heavy cornering; the same format used in Formula 1.
The instruments are mounted in a casing machined from solid aluminium which is housed in a carbon fibre dashboard. The interior displays uncompromisingly clean craftsmanship and features a host of carbon fibre applications – e.g. on the centre tunnel – aluminium, Alcantara and leather. The central panels and the seat cushions are perforated, with precision stitching gracing their outer edges.
Technical Features

The twelve-cylinder engine that powers the Reventón Roadster is a Lamborghini icon and one of the world’s most powerful naturally-aspirated engines.
With a compression ratio of 11 : 1 and a displacement of 6496 cc (396.41 in3,) it generates 670 PS (493 kW) at 8,000 rpm. Its maximum torque of 660 Nm (487 lb-ft) kicks in at 6,000 rpm.
Two chains drive the four camshafts that, in turn, operate the 48 valves. Together with the three-phase adjustable intake manifold, the variable valve timing delivers a meaty torque build-up. Dry sump lubrication ensures that the hi-tech power unit has a constant supply of oil, even under heavy lateral acceleration. The absence of the oil sump means a low mounting position – benefitting the car’s outstanding handling characteristics.
In classic Lamborghini style, the aluminium engine is mounted longitudinally in front of the rear axle, with the transmission ahead of it beneath the centre tunnel. This layout results in 58 percent of the overall weight being borne by the rear wheels.
This layout accommodates the Viscous Traction permanent all-wheel drive. Under normal conditions, it sends the vast majority of the driving force to the rear wheels. Should they begin to spin, the central viscous coupling sends up to 35 percent of the power via an additional shaft to the front axle. Limited-slip differentials are located there and at the rear axle with 25 and 45 percent lock respectively.
The e.gear automated six-speed sequential manual transmission is activated hydraulically via two steering wheel paddles. In addition to the “Normal” mode, the system offers a “Corsa” and a “low adherence” mode.
Each wheel boasts double wishbone suspension, with one spring strut on each side of the front axle and two each at the rear. The front end of the car can be raised by 40 mm (about 1.6 in.) to protect the underside of the vehicle over potholes or on steep entrances into underground garages.
The open two-seater runs on 18-inch wheels. The front tires measure 245/35, while the rears are 335/30. Dedicated air channels in the bodyshell cool the four wheel brakes. Carbon-fibre ceramic discs are standard – they have an extremely lightweight construction, operate with virtually no fade, are corrosion-free and achieve the highest service life. Each disc has a diameter of 380 mm (~15 in.) and is gripped by six-piston callipers.
A further distinctive characteristic of the Reventón Roadster is its calm directional stability even at extremely high speeds. Alongside the bodyshell design and the smooth underbody, which culminates in a powerfully formed diffuser, the rear spoiler deploys from the rear edge at about 130 km/h (80 mph) and adopts an even steeper angle as of about 220 km/h (136 mph).
Development

The design, CAD work and model making that took place in the Centro Stile, which opened in 2004, were accompanied continuously by specialists and test engineers from the Research & Development Department.
The Design Department is directly linked to the neighbouring Ufficio Tecnico, ensuring rapid implementation of ideas. Lamborghini’s capabilities also include the independent development of the complete electronic platform. This incorporates all control units – including those for the V12 and the innovative cockpit displays.

All units of the Reventón Roadster are being built on the Sant’Agata Bolognese production line.

At the Frankfurt Motor Show Lamborghini unveiled the Reventon, an extreme and exclusive sportscar with an aeronautics-inspired design and a 650 hp 12-cylinder engine. It will be produced in 20 units with a price of 1 million Euros.

The Concept

Although it is based on the Murciélago LP640, the exterior design of the Reventón is completely new.
It represents the ultimate symbol of Lamborghini's philosophy of creating extreme super sports cars without compromise.
Although sensuality and provocation characterise every Lamborghini, “however, the Reventón is the most extreme of all, a true automotive superlative.
"Our designers at the Lamborghini Style Centre took the technical base of the Murciélago LP640 and compressed and intensified its DNA, its genetic code,” affirms Stephan Winkelmann, President and CEO of Automobili Lamborghini S.p.A.
The Lamborghini Reventón has been entirely designed in Sant’Agata Bolognese, the original birthplace of the Lamborghini and the native home of every super car born under the sign of the bull.
The design drawn up in Lamborghini’s Centro Stile (Style Centre) is fine-tuned in close collaboration with the Lamborghini Research and Development Department.
Thus, the Reventón is not only “haute couture” but it also stands out for its elevated dynamism whilst being entirely suitable for every day use.
The Lamborghini Reventón is not destined to remain a one-off. A total of 20 Lamborghini friends and collectors will be able to own this extraordinary car and, naturally, enjoy the incomparable pleasure of driving it.
The name Reventón has been chosen according to Lamborghini tradition. Reventón was a fighting bull, owned by the Don Rodriguez family. It is included in the list of the most famous bulls ever and is known for killing the famed bullfighter Felix Guzman in 1943.
Airplane inspiration

"The present day Lamborghini models are distinguished by the clear language of their shape: sharp edges, precise lines and clean surfaces, which are iingredients of a style reduced to the essential. Each element is created exactly according to its function".
With the Reventón the Centro Stile designers have coherently developed this philosophy, inspired by another sphere where speed and dynamism reign absolute: modern aeronautics.
This has created an extremely precise, technically striking style with a new vitality: interrupted lines and contorted surfaces create a fascinating play of light, giving the car incredible movement.ù
Above: the debutof the Lamborghini Reventon at the 2007 Frankfurt Motor Show Just like the Murciélago LP640, the exterior is made of CFC, a composite carbon fibre material, which is as stable as it is light. The exterior components are glued and fixed to the body comprised of CFC and steel.
The front is characterised by the acute angle of the central ‘arrow’ and by the powerful forward-facing air intakes supply a lage of bolume of air, necessary to cool the carbon brake disks and the six cylinder callipers.
In Lamborghini's 12-cylinders tradition, both doors on the Reventón open upwards.
With their asymmetric configuration, the large air intakes below the doors provide an example of the extreme coherence with which a Lamborghini fulfils its function: on the driver's side it is large to increase the flow of oil to the radiator. On the passenger’s side of the vehicle, the air intake is flat because in this case, it only has to ensure the flow below the floor.
The aerodynamically optimised flat floor structure terminates at the rear with a diffuser featuring an accentuated shape. This guarantees excellent road grip and stability even at 340 km per hour.
Design details

The engine hood is made of glass laminate with open ventilation slits that offers a glimpse of the twelve cylinders. The glass also features the marked arrow angle that characterises the design from the front to the rear spoiler. The Lamborghini designers’ love for detail is beautifully illustrated by the fuel tank lid: a small mechanical work of art, achieved by milling a solid aluminium block.
The combination lights transform the incisiveness of the design into light: the front features the most modern light-emitting diodes alongside Bi-Xenon headlights. Seven LEDs ensure continuous daylight while there are a further nine diodes for the indicator and hazard lights.
Another technical innovation is found in the rear light LEDs. Because of the high temperature in the rear low part of the car, special heatproof LEDs are used for the indicator and hazard lights, stoplights and rear lights with a triple arrow optical effect.
The 20 units of the Reventón will be painted with a new homonimous hue: a mid opaque green/grey without the usual shine. However, thanks to the metallic particles, in the daylight this colour tone features surprising depth.
The specific wheels feature opaque carbon fins that are screwed onto the black aluminium spokes, creating a turbine effect and ensuring effective cooling for the ceramic brake disks.
Interior Design

The same innovative force applied to the exterior design characterises the cockpit of the Reventón. Designed and created using Alcantara, carbon, aluminium and leather that comply with the top quality standards, the interior is inspired by the next generation cockpits: just like in modern airplanes, the instruments comprise three TFT liquid crystal displays with innovative display modes.
At the touch of a button, the driver can choose from two vehicle information display modes. The instruments are housed in a structure milled from a solid aluminium block, protected by a carbon fibre casing.
The G-Force-Meter is also completely new: this display shows the dynamic drive forces, longitudinal acceleration during acceleration and braking, as well as transversal acceleration around bends.
These forces are represented by the movement of an indicator on a graduated 3D grid depending on the direction and intensity of the acceleration. A similar instrument can be found in the airplanes. Formula One teams also use a similar device to analyse dynamic forces.
The instrument on the left of the speedometer associates the number of revolutions in the form of a luminous column with the display of the selected gear. Finally, every Reventón is equipped with a robotised e.gear controlled by two small levers under the steering wheel.
By simply pressing a button, the driver can switch to the second, quasi-analogical display, where the classic circular instruments, speedometer and engine speed indicator are configured in an equally innovative way and transformed into luminous pilot lamps with varying colours. The G-Force-Meter naturally remains at the centre in this display mode.
In-house developed electronic systems
All this is possible thanks to the fact that the entire electronic platform of the Reventón, together with all the control devices, has been autonomously developed by the Lamborghini experts.
The same process for integrating the electronic displays in the car was applied to the Lamborghini Engineering Department.
About the Lamborghini Centro Stile

The Reventon was entirely developed at Sant'Agata Bolognese: from CAD design and development, to the creation of the prototype in the Prototype Department.
Inaugurated in 2004, the Centro Stile is dedicated to design and characterised by a high degree of efficiency: an “atelier” of creators, designers and prototype constructors, who encapsulate the Lamborghini culture and spirit by using their remarkable skills to create aesthetic innovation.
The Centro Stile is located in a 2,900 square two-storey building.
The large pavilion houses two test floors and related production and analysis equipment, while other rooms are set aside for the most advanced computerised workstations for designers and a style-model construction workshop. The Centro Stile is also closely linked to the nearby Engineering Department: the direct line between the Lamborghini development departments guarantees that ideas rapidly become reality.
The Lamborghini Reventón is a practical illustration of the streamlined functionality and efficiency characterising the Centro Stile: it took less than a year to progress from the first ideas to the finished car.
The complete design process from the first sketches on paper, to three dimensional computer models with 1:10 or 1:4 scale, right up to the real size prototype is organised around streamlined, fast, efficient work groups.
Thanks to the Centro Stile, for the first time in its history, Lamborghini is now able to create its own style philosophy in-house without having to rely on any external collaboration.
The 20 units will be manufactured in Sant’Agata, using a production process characterised by expert cfraftmanship and rigorous quality standards.
Lamborghini Reventon - Technical Features

The technoloy derives from the Murciélago LP640 with no major modifications: the engine is the classic twelve-cylinder engine with 6.5 litre displacement, tuned to deliver 650 HP (478 kW) at 8,000 rpm and a max torqu of 660 Nm.
Technical highlights include the robotised e.gear and the permanent Viscous Traction four-wheel drive system.

Lamborghini has released a set of new images of the Reventon, the extreme supercar based on the Murcielago, designed by its Style Center and unveiled at the 2007 Frankfurt Motor Show.

Planned to be produced in just 20 units, the Reventón was designed and engineered by Lamborghini starting from a "standard" Murciélago LP64. The whole development - from the first ideas to the finished car - took less than a year.
Powered by a 6.5 liter V12 engine with delivering 650 HP (478 kW) at 8,000 rpm and a max torque of 660 Nm, the Reventón accelerates from 0 to 100 km/h in just 3.4 seconds, and can reach a top speed of more than 340 km/h.
