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 centre 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 Reventon 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 Reventon 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 Reventon 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 Reventon 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 neighboring 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 Reventon Roadster are being built on the Sant'Agata Bolognese production line, with perfect craftsmanship and to the highest levels of quality.
