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 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.
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 respectively.
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.
