Lamborghini Reventón Roadster Shows Off That $1.6 Million Body

Illustration for article titled Lamborghini Reventón Roadster Shows Off That $1.6 Million Body

Looking to drop around $1.6 Million on a two-seat convertible? You and 19 of your fellow oil sheikhs might want to consider the 205 MPH Lamborghini Reventon Roadster. Think of it like buying a jet plane cockpit without the canopy.


The Lamborghini Reventón roadster's pretty much exactly like the non-drop-top Reventón, except, you know, the roof comes off. Full press release below.

Lamborghini Reventón Roadster – ultimately open Designer piece with uncompromising performance

Sant'Agata Bolognese, 14 th September 2009 - Lamborghini presents the ultimate driving machine among open-top two-seaters – the Reventón Roadster is a sports car of breathtaking fascination, menacing power and uncompromising performance. The 6.5 liter twelve-cylinder generates 493 kW (670 PS), catapulting the Roadster from 0 to 100 Km/h (0 to 62 mph) in 3.4 seconds and onwards to a top speed of 330 KM/h (205 mph). The open-top Reventón is not only one of the fastest, but also one of the most exclusive cars in the world – Lamborghini has limited the series.

The Lamborghini Reventón is not destined to remain a one-off. Less than 20 Lamborghini friends and collectors will be able to own this extraordinary car and, naturally, enjoy the incomparable pleasure of driving it.

Each Reventón Roadster will be sold for 1.1 Million Euro (without taxes). Deliveries will begin October 2009.

"The Reventón is the most extreme car in the history of the brand," comments Stephan Winkelmann, President and CEO of Automobili Lamborghini S.p.A. "The new Roadster adds an extra emotional component to our combined technological expertise – it unites superior performance with the sensual fascination of open-top driving." The Reventón Coupé was presented at the 2007 IAA in Frankfurt and was sold out immediately.

Open-top sports cars are a tradition at Lamborghini that stretches back over 40 years. In 1968, the company from Sant'Agata Bolognese built a Miura without a fixed roof as a one-off. The Diablo Roadster appeared in 1995 with its targa roof anchored to the engine cover.

Sculpture with extreme dynamics

All Lamborghinis are created with an avantgarde approach to design; a fast-moving technical sculpture. 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.

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 – the Roadster is clad in a design of maximum functionality and spectacular clarity. 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 bonnet is virtually horizontal and a total of four windows made from
glass provide a view of the mighty V12 in all its technical elegance.

Stiff bodyshell base

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 fiber elements, with sheet steel used only
for the outer door skins.

Exclusive grey paintwork

A unique paint finish completes the razor sharp design language of the
Lamborghini Reventón Roadster. For this exclusive 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 matt 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.

Aircraft-style displays

The interior of the Reventón Roadster conveys the same powerful design as the
exterior. 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 color 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 aluminum which is
housed in a carbon fiber dashboard. The interior displays uncompromisingly
clean craftsmanship and features a host of carbon fiber applications – e.g. on the
center tunnel – aluminum, Alcantara and leather. The central panels and the seat
cushions are perforated, with precision stitching gracing their outer edges.

Lamborghini has equipped the Reventón Roadster with full options.

An icon of engine design

The twelve-cylinder engine that powers the Reventón Roadster is a Lamborghini
icon – and the technical feature that defines the character of the car. It is 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 in
,) 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.

The V12 engine is a masterpiece of Italian engineering. Two chains drive its 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

The V12 catapults the Reventón Roadster from 0 to 100 Km/h (0 to 62 mph) in
3.4 seconds and onwards to a top speed of 330 Km/h (205 mph). It reacts with
the eagerness of a racing engine to input from the right foot, revving to 8,000
rpm and beyond, and performing a symphony that sends shudders along the
spine. The deep booming bass, the powerful mid-range and the exultant horn
section play music that, once heard, can never be forgotten.

All-wheel drive for maximum traction

In classic Lamborghini style, the aluminum engine is mounted longitudinally in
front of the rear axle, with the transmission ahead of it beneath the center
tunnel. This layout results in 58 percent of the overall weight being borne by the
rear wheels – ideal for a powerful sports car.

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

Lamborghini introduced the all-wheel drive principle with the Diablo. The reason
back then was just as clear as it is today - four driven wheels grip far better than

two, and the more powerful the engine, the greater the impact of this
fundamental law of physics.

Also standard on the Reventón Roadster is the e.gear automated six-speed
sequential manual transmission. The driver controls the gear shift, which is
activated hydraulically via two steering wheel paddles. In addition to the
"Normal" mode, the system offers a "Corsa" and a "low adherence" mode. The
driver just has to keep his foot to the floor - the rest is handled by e.gear.

Running gear layout from motorsport

The Reventón Roadster keeps the extreme power of its engine in check with a
running gear layout derived directly from motorsport. 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-fiber 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 calipers.

As fast as the open two-seater may be, its road manners are impeccable. Its
performance limits are extremely high, yet effortless to control. And, on exiting a
bend, all four wheels stick tenaciously to the asphalt. The permanent all-wheel
drive dovetails the car firmly with the road, delivering decisive benefits in
traction and stability.

High-performance aerodynamics

A further distinctive characteristic of the Reventón Roadster is its calm
directional stability even at extremely high speeds – a feature that also turns fast
highway stretches into sheer joy. Alongside the bodyshell design and the smooth
underbody, which culminates in a powerfully formed diffuser, the rear spoiler
carries responsibility for downforce. It 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). The entire aerodynamic concept – around and through the car – is radically
laid out for performance.

State-of the-art development techniques

Lamborghini used state-of-the-art, highly networked processes to bring the
Reventón Roadster to life. 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, with perfect craftsmanship and to the highest levels of quality.
