Reventón Roadster: 6.5 litre V12, generating 670 PS (661 bhp).

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 maker.

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?

Inspiration from fighter jets.

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 month.

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.

Specific output 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.

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.

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 particles.

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 discs.


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 transmissive (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.

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 sports car.

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 system.

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 e.gear.


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 rear.

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 wheel brakes. 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.
