Air and space — the aerodynamic roadster design
The roadster maintains the unmistakable design of the Aventador S along with unique features reflecting its roadster persona: a combination of distinctive Lamborghini design DNA and the result of extensive aerodynamic testing.
The car’s rear sports distinctively different lines to the coupé, giving the roadster its own aerodynamic character. An engine bridge runs from the back window to the rear in a mix of body color and matt black painted carbon fiber engine bonnet blades: a transparent option is also available to show off the V12 engine within.
Sleek, removable, hardtop roof panels, weighing less than six kg, are convexly molded to ensure maximum cabin space for the occupants. Finished in matt black carbon fiber, optional specifications including high gloss black, shiny visible carbon fiber, and further Ad Personam possibilities. An easy fastening system allows the roof panels to be quickly removed and stored in the front trunk.
The rear window is electrically operated at the push of a button for drivers wanting to hear the beat of the V12 powerplant: while closed during roofless driving, the window minimizes cabin noise and airflow.
Color and trim, inside and out
Complementing external colors, five interior configurations are offered, featuring leather and Alcantara in single and bi-color combinations and various stitching and trim choices. Further external and internal packages such as ‘branding’ and ‘carbon fiber’ are offered, with the Ad Personam program for clients wanting to customize their Aventador S Roadster even further.
Clients can also select the internal specification of the roof panels: covered in black Alcantara framed by matt black carbon as standard, an optional Carbon Skin package (Lamborghini’s high tech fabric that is even lighter than Alcantara) can cover the interior roof panels as well as around the cockpit and parts of the cabin.
The Aventador S Roadster is launched in the Ad Personam Color Blu Aegir, inspired by the peaceful turquoise ocean hiding an indomitable force beneath: sophisticated yet powerful, with extensive use of carbon fiber.
The wing mirrors and windscreen frame are finished in high gloss carbon fiber while the lower part of the car including front and rear bumper, side skirts, air intakes and outlets are in visible carbon fiber.
The configuration internally demonstrates the potential of the Ad Personam program, using Blu Delphinus leather contrasted with Bianco Polar, with Blu Delphinus S-trim stripes on seats, doors and dashboard and even the floor mats in blue and white.
Aventador S Roadster — design and technologies
The Aventador Roadster’s ‘S’ suffix denotes the design and technology advancements of the new model. The Roadster adopts the four-wheel drive, new active suspension, new four-wheel steering system, and the new EGO driving mode introduced on the Aventador S coupé, and with the redevelopment of every aspect of suspension and electronic control systems, its ‘total control concept’ assures superior drive, ride and performance.
Enhanced lateral control from the new four-wheel steering provides improved agility at low speed and more stability at high speed, combined with Lamborghini Dynamic Steering (LDS) for responsive feedback and sharper turn-in. Improved vertical control comes from updated pushrod suspension, new rear springs and Lamborghini Magneto-rheological Suspension (LMS) with revised kinematics adapted to the new four-wheel steering. A new real-time variable damping system optimizes wheel and body control and balance and ground stiffness is maximized.
A optimized ESC system improves longitudinal control for faster and more precise management of traction control and vehicle dynamics depending on driving mode selected, maximizing grip in all conditions and enhancing handling. The permanent four-wheel drive’s calibration allows for the stabilizing effect of the new rear-wheel steering, allowing more torque to the rear axle: when powering off, less torque is shifted to the front axle to allow a sporty but safe drive.
The active rear wing optimizes the car’s aerodynamic balance depending on speed and the selected drive mode, and its significantly enhanced overall aerodynamic design improves front downforce by more than 130% over the previous Aventador. With the wing in optimum position the roadster achieves over 50% overall efficiency at high downforce and in low drag more than 400%.
The Aventador S Roadster’s four driving modes allows selection of STRADA, SPORT and CORSA and the new EGO mode, each influencing every aspect of the car’s behavior through management of traction, steering and suspension. EGO allows the driver to set up his preferred criteria in each mode to suit his driving style.
Accelerating 0-100km/h in just 3.0 seconds, with a top speed equal to the Aventador S coupé of 350 km/h, the Aventador S Roadster weighs just 50 kg more than the coupé. Its 6.5 liter V12 engine outputs the same 740 hp as the coupé, with 690 Nm of torque at 5,500 rpm. The seven-speed lightweight Independent Shifting Rod (ISR) transmission provides robotized gearshifts in up to 50 milliseconds, with carbon ceramic brakes as standard. Dione 20″/21″ rims are fitted with Pirelli P Zero tires especially developed for the Aventador S. Inside, the TFT digital dashboard can be customized to the driver’s preferences and Apple CarPlay™ is standard.
The engine and exhaust
The Lamborghini Aventador’s naturally aspirated twelve cylinder, 6.5 liter engine outputs an additional 40 hp over its predecessor, to a maximum 740 hp, with a 690 Nm of torque at 5,500 rpm. To achieve the power increase, both VVT (Variable Valve Timing) and VIS (Variable Intake System) have been optimized in order to obtain an enriched torque curve. Additionally, the maximum engine revs have been increased from 8,350 to 8,500 rpm. A dry weight of just 1,575 kg provides a weight/to/power ratio of just 2.13 kg/hp. Acceleration from 0-100 km/h is reached in 2.9 seconds, with a top speed of 350 km/h. Transmission is provided by Lamborghini?s lightweight Independent Shifting Rod (ISR) 7-speed shifting system, providing robotized gear shifts in up to 50 milliseconds.
The Aventador S adopts a new exhaust system developed as the result of a significant R&D project. More than 20% lighter than its predecessor and the product of testing multiple configurations, the results are an enhanced Lamborghini sound and resonance from the already inimitable V12 aspirated engine, with the three single pipe outlets at the rear of the Aventador S a visual reminder of the new exhaust system.
As in its predecessor, the Aventador S is equipped with a stop-and-start system and cylinder deactivation for optimized engine efficiency. When full engine capacity is not required, six of the twelve cylinders are temporarily deactivated by switching off one cylinder bank. When the driver accelerates, the system switches back instantaneously to twelve-cylinder mode, with the changeover virtually impossible to detect by the driver.
Aventador S – a driver’s environment
The cockpit of the Aventador S brings new functionality and refinement. A new TFT digital dashboard can be customized according to the driver’s preferences, with different kombi screens for STRADA, SPORT and CORSA in conjunction with the EGO mode. Selected from the driving modes options on the control panel, the EGO button reveals further options on pop-up digital screens, allowing the driver to choose his preferred settings.
AppleCarPlay comes as a standard specification, allowing the cockpit’s occupants to manage voice activated communications and entertainment from personal Apple devices.
The Lamborghini telemetry system is an optional specification: recording lap times and track performance as well as trip data, the telemetry system is especially appealing to the owner who wants to take his car on track.
The interior specification of the Aventador S is virtually limitless through Lamborghini’s Ad Personam customization program.
Tires and braking system
The Aventador S sits on a new, specially developed set of Pirelli P Zero tires. Designed to optimize steering, traction, lane changes and braking efficiency, the tires are specifically designed to respond to the dynamic behavior induced by the Lamborghini Rear-wheel Steering, ensuring handling consistency and driver feedback. With improved force generation from both front and rear tires, the Pirelli P Zero tires provide a higher lateral acceleration and reduce understeer characteristics.
Carbon ceramic brakes are standard equipment for the Aventador S. The ventilated and perforated carbon ceramic discs (Ø 400 x 38 mm / Ø 380 x 38 mm) enhance braking performance from 100 km/h to standstill in 31 m.
