In March 2011, during the launch of the Lamborghini Aventador LP-700 4 at Geneva Motor Show, Stephan winkelmann, President and CEO of Automobili Lamborghini, She said: "The future of our supercars is already a reality thanks to the Aventador LP 700-4." His words had to do with the technical innovations used to create this iconic sports car, which over a decade had three other versions: Superfast, S y SVJ. Here are some of them ...
The Aventador LP 700-4, with a carbon fiber monocoque chassis never before seen in Lamborghini supercars, it established the brand's leadership in the production and development of composite materials, making the Sant'Agata manufacturer the first company to produce such a large number of carbon fiber elements in-house.
It uses a “single shell” monocoque, which combines the car interior, floor and roof in a single structure, thus guaranteeing extremely high structural rigidity. Together with the two front aluminum subframes and rear, it is an engineered solution that offers high structural rigidity and an exceptionally light weight of just 229,5 kg.
The roof of the Roadster version of the Aventador is made up of two sections made entirely of carbon fiber, a further advance over the Bat, which had a hood. These technologies guarantee not only an impressive aesthetic, but also a optimal stiffness even though the roof is extremely light. In fact, each section of the roof weighs less than 6 kg.
The use of carbon fiber was increased in the Superveloce version: it was used in the door panels and thresholds, remodeled in ultra-light composite materials (SCM), and in particular in the interior, where for the first time in a production car the Carbon Skin technology, a superlight material that, combined with a specialized resin, is very soft to the touch, extremely resistant to wear and tear and has great flexibility.
The power of the Lamborghini Aventador made it necessary to have an efficient transmission from the start to offer the driver the best possible driving experience. The electronic controlled torque sharing between the front and rear wheels is based on three components: a Haldex torque distributor, a rear limited-slip differential, and a front differential that works in conjunction with ESP. In a few milliseconds this system can adjust the torque distribution to the driving conditions of the vehicle and, in the most critical cases, can transfer 60% of the torque to the front axle depending on the driving mode selected by the driver.
ROBOTIZED GEARBOX WITH INDEPENDENT RODS (ISR)
The Aventador rides a robotic gearbox- a remarkable advance for a street supercar in 2011. The system (seven-speed plus reverse) provides extremely fast gear changes. The gearbox with independent rods (ISR) features two lightweight carbon fiber shift rods that move the synchromes simultaneously: one for the gear and one for disengaging. This system has made it possible for Lamborghini to make the gear changes in just 50 milliseconds, the speed at which the human eye moves.
From the very first version, the Lamborghini Aventador is equipped with the innovative Push Rod suspension system. This scheme, inspired by the F1, has bars attached to the lower part of the hub housing of each wheel, which "transmit (push) the force" to the shock absorber-spring assemblies installed horizontally in the upper part of the frame, both in the front and in the rear. rear. Suspension system Lamborghini Push Rod later incorporated into the Aventador Superveloce magneto-rheological dampers (MRS), which constantly modify the behavior of the suspensions depending on the road conditions and the driving style: the damping adjusts in each curve, greatly reducing the roll and making the driving and steering of the vehicle be more reactive. Is adaptive suspension it also reduces front axle sag during braking.
Since 2011, Lamborghini has been committed to reduce consumption and pollution and, above all, to increase efficiency. Starting with the LP 700-4 version, the Lamborghini Aventador is presented with an innovative and fast start-stop system with an electrical energy storage system, which allows a significant reduction in fuel consumption. The manufacturer of Sant'Agata has introduced in the new Aventador a cutting-edge technology, never seen before in the automotive industry: the electrical power to restart the engine after a stop (eg at traffic lights) is provided by the supercap energy storage system, which results in an extremely fast start. The V12 completes the process in 180 milliseconds, much faster than a conventional start / stop. Continuing with the Lamborghini philosophy of lightweight construction, the new technology means a weight reduction of 3 kg. The traditional car battery powers only the electronic systems, is smaller and lasts almost the entire life of the vehicle.
DRIVING MODE AND EGO MODE SELECTOR
La driving style setting it has also evolved in parallel in the Aventador. The Aventador LP 700-4's drive modes offered five gearbox modes: three manual (Strada, Sport and Corsa) and two automatic (Strada-auto and Sport-auto). In the Aventador Superveloce, however, these modes had a greater ability to modify the driving style, giving the option through the three modes of the Drive Select system (Strada, Sport and Corsa), to adjust the engine, transmission, differentials, dampers and steering. The Aventador S was a major evolution by allowing the driver to choose between four different driving modes: Strada, Sport, Corsa and Ego. The new ego driving mode allows the driver to choose from several additional configuration profiles that can be individually customized by modifying the behavior of the traction system, steering and suspension within the range of Strada, Sport and Corsa settings.
ACTIVE DYNAMICS OF THE LAMBORGHINI VEHICLE (LDVA)
In the Aventador, longitudinal control comes from the LDVA control unit, an improved ESC operating strategy first introduced in the Aventador S, offering faster and more precise control of traction and vehicle handling depending on the vehicle. selected driving mode. LDVA is a kind of electronic brain that receives accurate information in real time on the movement of the vehicle through the signals transmitted by all the sensors of the car. Therefore, you can instantly modify active systems to have the most suitable settings and ensure the best performance in all driving conditions.
LAMBORGHINI ACTIVE AERODYNAMIC
To improve the Aventador's road holding and performance, the Lamborghini Activa 2.0 Aerodynamics system was introduced in the SVJ version, as well as an improved second generation LDVA system. Lamborghini's patented ALA system, which first appeared on the Huracán Performante, has been updated to evolve to the ALA 2.0 system on the Aventador SVJ. It was recalibrated to account for the greater lateral acceleration of the car and at the same time, new car designs were introduced air intakes and aerodynamic ducts.
The ALA system modifies the aerodynamics to achieve high load or low aerodynamic resistance depending on dynamic conditions. Electronically actuated motors open or close the active flaps on the front splitter and on the hood, which direct airflow to the front and rear. The LDVA 2.0 control unit, with improved inertia sensors, controls all the electronic systems of the car in real time, activating the flaps of the ALA system in less than 500 milliseconds to guarantee the best aerodynamic configuration in any driving condition.
STEERING TO THE FOUR WHEELS
With the launch of the Aventador S, lateral control benefited from the all-wheel steering system, installed for the first time in a Lamborghini production car. This system provides greater agility at low and medium speeds and greater stability at high speeds. It is combined with Lamborghini Dynamic Steering (LDS) on the front axle, ensuring a more natural response and greater reactivity in the tightest corners, and is specifically adapted to work together with the system of Lamborghini Rear Steering (LRS). Two independent actuators react within five milliseconds to the driver's steering movements, allowing you to adjust the angle in real time and improve the balance between road grip and traction. At low speed, the rear wheels turn in the opposite direction to the steering angle, thus practically reducing the wheelbase. On the other hand, at high speed, the front and rear wheels turn in the same direction as the steering, a configuration that allows the wheelbase to be increased virtually, ensuring greater stability, and optimizing the vehicle's reactivity.
CYLINDER SELECTIVE DEACTIVATION SYSTEM (CDS)
The second technology that increases efficiency is the Selective Cylinder Deactivation System (CDS). When driving with a reduced load and at speeds below 135 km / h, the CDS deactivates one of the two cylinder banks, so that the motor works as a six cylinders in line. At the slightest touch on the accelerator, all the power is available again. Both the CDS and the start-stop system react incredibly quickly, practically without the driver noticing and without detracting from the excitement of driving. However, they provide a significant improvement in efficiency: Compared to the same car without these technologies, the Aventador's combined fuel consumption is reduced by 7%. At highway speeds of around 130 km / h, the reduction in fuel consumption and polluting emissions is around 20%.
If we review the origin of the names of the Lamborghini models, those of Sant'Agata Bolognese take their names from fighting bulls: Miura, Jarama, Blowout y Bat, but one of the most energetic bulls was Aventador.
Aventador proved to be the bravest bull in the Zaragoza bullring in 1993. Throughout its history, the supercar launched by Automobili Lamborghini in 2011 has proven its importance by moving decisively forward in the automotive sector thanks to its ten years of innovation .
