The new Lamborghini Aventador S is characterised by new aerodynamic design, redeveloped suspension, increased power and new driving dynamics
The ‘S’ is the suffix of previous enhanced Lamborghini models and defines a new benchmark for the V12 Lamborghini.
“This is the next generation Aventador as well as the expression of new technological and performance milestones in super sports car development,” says Automobili Lamborghini Chairman and Chief Executive Officer Stefano Domenicali. “The Aventador S is visionary design, cutting-edge technology and driving dynamics in pure harmony, and elevates the concept of super sports cars to a new level.”
Design and Aerodynamics
The design of the new Aventador S clearly indicates the new Aventador generation. The Aventador S features a number of exterior developments, particularly in front and rear, while its profile remains clearly an Aventador. Every modified component is redesigned for a purpose, achieving maximum aerodynamic efficiency while accenting the Aventador’s complex, muscular dynamism. Furthermore, Lamborghini Centro Stile has intelligently integrated certain elements of past icons, such as the lines of rear wheel arches reminiscent of the original Countach.
A more aggressive nose and longer front splitter redirect airflow for better aerodynamic efficiency with improved engine cooling and increased cooling to the radiators. Two air ducts located on the side of the front bumper reduces aerodynamic interference from the front tyres and optimise wake flow to the rear radiator.
The rear of the Aventador S is dominated by a black diffuser, available on request in carbon fibre, characterised by a number of vertical fins that amplify the airflow effects, reduce drag through pressure recovery and generate downforce. Three single exhaust outlets exit through the rear bumper.
The active rear wing is movable in three positions depending on speed and drive select mode and optimises the car’s improved overall balance, working with vortex generators created in the front and rear of the chassis’ underside that maximises air flow as well as assist in brake cooling.
The Aventador S design results in significantly enhanced aerodynamic performance. Front downforce has been improved by more than 130% over the previous Aventador coupé. When the wing is in its optimum position the overall efficiency at high downforce is improved by over 50%, and in low drag by more than 400% compared to the previous model.
Four masterpieces evolve driving emotion:
Four-wheel drive, new active suspension, new four-wheel steering system and the new EGO driving mode
The Aventador S chassis retains the Aventador’s unique and extremely rigid lightweight carbon fibre monocoque with attached aluminium frames resulting in a dry weight of just 1,575 kg.
The Aventador S is redeveloped around a ‘total control concept’ to provide a superior drive, ride and performance; every aspect of the car’s suspension and electronic control systems has been advanced, with the goal of particularly enhanced control and driving emotion.
Enhanced lateral control comes from new four-wheel steering, adopted for the first time on a series production Lamborghini. The system provides improved agility at low and medium speeds and more stability at high speed. On the front axle, it is combined with Lamborghini Dynamic Steering (LDS), tuned for a more natural and responsive feel with a sharper turn-in. It is specially adapted to integrate with the active Lamborghini Rear-wheel Steering (LRS) on the rear axle: two separate actuators react in five milliseconds to driver’s steering movements, allowing a real-time angle and cornering stiffness adjustment.
At low speeds, front wheels face in opposite direction to the steering angle, thereby virtually reducing the wheelbase. With less steering wheel angle required, the Aventador S is more agile with a reduced turning radius, ensuring higher performance in curves and making it easy to manoeuvre in town and at low speeds.
Conversely at higher speeds both front and rear wheels share the same steering angle, thus virtually extending the wheelbase, providing increased stability and optimising the responsiveness of the car.
Vertical control comes from Lamborghini’s updated pushrod and Lamborghini Magneto-rheological Suspension (LMS), with revised kinematics adapted to the new four-wheel steering. New suspension geometry, optimised for Lamborghini Rear-wheel Steering, includes upper and lower arm and wheel carrier to reduce caster and load on the system. A new real-time variable damping system optimises wheel and body control, and balance and ground stiffness is maximised. New rear springs also enhance the car’s balance.
Longitudinal control is achieved via an improved ESC strategy with faster and more precise control of traction control and vehicle dynamics, depending on the driving mode selected. Extensively tested on surfaces such as snow and ice, the Aventador S has improved adhesion detection to maximise grip in all conditions and enhance its handling capabilities. The Aventador S permanent four-wheel drive has been calibrated for the stabilising effect of the new Lamborghini Rear-wheel Steering, allowing more torque to the rear axle: when powering off the throttle, less torque is shifted to the front axle to allow over-steer behaviour and a sporty, but safe drive.
Lamborghini engineers have integrated the smart Lamborghini Dinamica Veicolo Attiva (LDVA) control unit to manage these systems in the car. LDVA is the new brain of the car, which receives real-time and precise information on body motion via input from all sensors of the car. It instantly defines the best set-up of all active systems in order to guarantee the best vehicle dynamics in each and every condition.
