Oficial: Lamborghini Reventón Roadster – complete details image

Lamborghini presents the ultimate driving machine among open-top two-seaters – the Lamborghini Reventón Roadster is a sports car of breathtaking fascination, menacing power and uncompromising performance. The 6.5 litre 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.

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

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 fibre 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.

Engine
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.

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 characteristics.

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.
