Less than 20 Lamborghini Reventón
Roadster, each for E1.1 million
Aviation on earth... open to the skies
18 Sep. 2009 - As one of the major exclusive
sports cars brands, Lamborghini didn't want to come the 63rd Frankfurt
motor show (public days from 17 to 27 September) just like any other car
The best way to go a step higher is to bring an
exceptional, a really exceptional sports car that makes just seeing it an
event in itself.
Such a car should start with a limited production run.
A few hundred units? No, that's still "too many" for the Reventón Roadster!
To be precise: "Less than 20 Lamborghini friends and collectors
will be able to own" the Lamborghini Reventón Roadster, says the
Audi-owned Italian brand (within the German VW group).
How much will it cost?
Well, as they would say in the Rolls-Royce literature,
if you ask about the price, it may well mean that you cannot afford it.
But since you insist, each Reventón Roadster will be
sold for 1.1 Million Euro (without taxes), with deliveries starting next
That makes the open-top two-seater Reventón 0.1
Million Euro dearer than the Reventón Coupé which was presented at the
previous Frankfurt motor show, two years ago. The coupé was also with a
limited run of just 20 units.
of 103 PS, 101.75 bhp, 75.9 kW per 1000 cc.
Now that we know where to stand in price and
availability terms, most of us will be, out of curiosity, more interested
to know about the 6.5-litre V12, AWD machine, at least to see why should
this 670 PS beast be such a... "good bargain"!
Exceptional as it must be, the Lamborghini Reventón
Roadster sports the 6.5 litre V12 engine, generating
493 kW (670 PS, 661 bhp), with a specific
output figure of 103 PS, 101.75 bhp, 75.9 kW per 1000 cc.
Let's start from outside. The design of the Roadster’s
long back is 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 central-rear mounted V12 volcano.
mounted V12 "volcano" under glass windows.
Basically, the Reventón Roadster is derived from the
Coupé, with the same inspiration from fighter jets. And it shows it
instantly in the 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.
Like the Coupé, the Reventón
Roadster measures 4700 mm (185 in.) long, with a wheelbase of 2665 mm
(105 in.). It is 2058 mm (81 in.) wide and 1132 mm (45 in.) high (see the Reventón
Roadster specifications page). The driver and passenger seating
positions are low and separated by a substantial central tunnel.
The base bodyshell of the Reventón Coupé is stiff
enough to require only minimal reinforcement for the Roadster. It has a
dry weight of 1690 kg (3,725 lbs.), 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.
applications, aluminium, Alcantara and leather.
A unique paint finish completes the sharp design
language of the Lamborghini Reventón Roadster: 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 impression of depth thanks to special metal
Technically stylish details include the bi-xenon
headlamp units with LEDs forming the daytime running lights and
indicators. The rear lamps are also equipped with LEDs.
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 an unusual visual impact in
addition to a turbine effect that improves cooling of the ceramic brake
The cockpit of the Reventón Roadster is structured
with technical clarity, the interfaces arranged for functionality. Like a
modern aircraft, the open two-seater has no classic analogue
instrumentation. Information is delivered via liquid-crystal displays, one
(using backlight) and two transflective
(transmissive and reflective methods) ones.
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.
clarity, interfaces arranged for functionality and no
analogue instrumentation as information is delivered via
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 a host of carbon fibre applications (as on the centre tunnel),
aluminium, Alcantara and leather. The central panels and the seat cushions
are perforated, with precision stitching on their outer edges.
Behind the two seats are two hidden pop-up bars that
deploy upwards in 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.
0-100 km/h (0-62
mph): 3.4 s. Top speed: 330 km/h (205 mph) .
The twelve-cylinder engine that powers the Reventón
Roadster is one of the world’s most powerful naturally-aspirated
engines. With a compression ratio of 11 to 1, and a displacement of
6496 cc (396.41 in3), it generates 670 PS (493 kW, 661 bhp) 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 of the V12 which also benefits from a three-phase
adjustable intake manifold and variable valve timing.
Dry sump lubrication ensures constant supply of oil,
even under heavy lateral acceleration. The absence of the oil sump helps
lower the mounting position and consequently, contributes to a lower
gravity centre that further enhances the car’s handling characteristics.
The V12 launches 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) where legal and objective conditions allow, of course.
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. 58 percent of the overall weight
goes on the rear wheels, which is a logical distribution for such a super
This layout accommodates what Lamborghini calls the
"viscous traction permanent all-wheel drive".
Under normal conditions, the AWD system sends most of
the driving force to the rear wheels. If they begin to spin, the central
viscous coupling sends up to 35 percent of the power via an additional
shaft to the front axle. That's on the longitudinal, rear / front
distribution of engine torque.
Engine torque is also distributed between the two sides
of the car, as a limited-slip differential distributes torque between the
wheels of each axle, with 25 percent (front axle) and 45 percent (rear
axle) lock respectively.
Lamborghini introduced the all-wheel drive principle
with the Diablo, as four driven wheels grip far better than two, and the
more powerful the engine, the greater the impact of this rule. It is worth
mentioning also that within the VW group, Lamborghini is affiliated to
Audi, a brand known for its very successful quattro all-wheel drive
A rear spoiler
deploys from the rear edge at about 130 km/h (80 mph) and
adopts an even steeper angle at 220 km/h (136 mph), adding
downforce on the rear wheel.
With these standard systems, the Reventón Roadster
gets also 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 can
keep his foot to the floor, leaving the rest to be handled completely by
The Reventón Roadster has 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
The front end of the car can be raised by 40 mm (about
1.57 in.) to protect the underside of the vehicle over potholes or on
steep entrances into underground garages.
With the 18-inch wheels, tires measure 245/35 at the
front and 335/30 at the rear.
Dedicated air channels in the bodyshell cool the four
Carbon-fibre ceramic discs are standard. They have a very lightweight
construction, operate with virtually no fade, are corrosion-free and
achieve the highest service life. Each disc has a diameter of 380 mm
(14.96 in.) and is gripped by six-piston callipers.
Lamborghini mentions a further characteristic of the
Reventón Roadster: a "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), adding downforce on
the rear wheel, which receive most of the engine torque.
All units of the Reventón Roadster are being built on
the Sant’Agata Bolognese production line. 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. Lamborghini’s capabilities
also include the independent development of the complete electronic
platform, with all control units, including those for the V12 and the
innovative cockpit displays.
