2017 Lamborghini Aventador S vs 2017 Bugatti Chiron

Lamborghini Press Release Highlights

The new Lamborghini Aventador S is characterized 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. The design of the new Lamborghini 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.

The Lamborghini 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.
Powertrain
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 Lamborghini 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.
Chassis
Four masterpieces evolve driving emotion: Four-wheel drive, new active suspension, new four-wheel steering system and the new EGO driving mode. The Lamborghini Aventador S chassis retains the Aventador's unique and extremely rigid lightweight carbon fiber monocoque with attached aluminum frames resulting in a dry weight of just 1,575 kg. The Aventador S allows the driver to select between four different driving modes: STRADA, SPORT, CORSA and the new EGO mode, which influence the behavior of traction (engine, gearbox, 4WD), steering (LRS, LDS, Servotronic) and suspension (LMS). All driving modes have been recalibrated in the Lamborghini Aventador S, improving ESC integration with all-wheel drive and the interface between engine torque management system and traction control reaction.

Enhanced lateral control comes from new four-wheel steering, which 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 allowing a real-time angle and cornering stiffness adjustment.

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, optimized 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 optimizes wheel and body control, and balance and ground stiffness is maximized. New rear springs also enhance the car's balance.

Lamborghini engineers have integrated the smart Lamborghini Dinamica Veicolo Attiva (LDVA) control unit to manage these systems in the car. 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.
Technology
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.

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. AppleCarPlay comes as a standard specification, allowing the cockpit's occupants to manage voice activated communications and entertainment from personal Apple devices.

Bugatti Press Release Highlights

Bugatti is unveiling the Bugatti Chiron, the most powerful, fastest, most luxurious and most exclusive production super sports car in the world. The Bugatti Chiron is the latest generation of the ultimate super sports car and is a completely new development. The sports car manufacturer from Molsheim, with its long tradition, has taken the unique features of a modern Bugatti to a new level and developed a high-performance machine that has become significantly better in every respect. With a power output of 1,500 HP, unprecedented for production vehicles, an exceptionally high torque value of 1,600 Nm between 2,000 and 6,000 rpm and a wide variety of technical innovations, the Chiron sets new standards in every respect. The Bugatti Chiron is therefore very well-positioned to become the next world speed record holder and reach a maximum speed significantly above the record currently held by Bugatti. The manufacturer has limited the maximum speed of the new car to 420 km/h for road use. Only 500 of these exceptional cars are to be produced. The basic price is €2.4 million net.

With the new carbon fiber monocoque, a newly designed adaptive chassis, tires developed especially for Bugatti and other innovative technologies, the Chiron is not only a champion in terms of maximum acceleration but is, for the first time, also an agile, modern Bugatti with handling that ensures maximum driving pleasure. The design of the Bugatti Chiron combines significantly more "beast" with a very high level of "beauty". The design language introduced by Bugatti with the Chiron has a significantly more aggressive tone and does justice to the character of the new super sports car. The designers have succeeded in reinterpreting Bugatti's DNA with its distinctive features in a modern manifestation at the same time as adding new features resulting from the technical demands of even higher performance. The Chiron remains unmistakably a Bugatti.
Powertrain
1,500 HP was the power target for the Bugatti Chiron. This is the result of the legendary and unique eight-liter W16 engine that has been newly developed by Bugatti. In its Top Speed mode, the car reaches the maximum speed of 420 km/h, limited for road use - however, this is by no means the end of the road for the Bugatti Chiron. To achieve a power boost of 25 percent compared with the predecessor, almost every component of the engine was considered and redesigned. To compensate for the weight increase caused by the high power output, greater use is made of lightweight materials such as titanium and carbon fiber.

The key factors in the increased power output are four larger higher-performance turbochargers and duplex fuel injection with 32 injectors. The charge air cooling system has been improved. As a result, more than 60,000 liters of air per minute are pumped through the engine. The coolant pump also circulates 800 liters of water in one minute through the entire engine. Another feature that boosts the power output is the new titanium exhaust system with reduced exhaust gas back pressure.

The powertrain features a front-axle differential with integrated inter-axle lock and a rear-axle differential with integrated inter-wheel lock and a seven-speed dual-clutch gearbox designed for a torque of 1,600 Nm. This gearbox developed especially by Bugatti has the largest, highest-performance clutch used on a passenger car. The Chiron has permanent four-wheel drive.
Chassis
The monocoque of the Chiron is made entirely from carbon fiber and is designed for crash protection. This newly developed unit is the technically most sophisticated monocoque in its class. If all the fibers used in the monocoque were laid out end to end, they would stretch nine times the distance between the earth and the moon. The production of a monocoque takes four weeks. Bugatti has developed an adaptive chassis for the Chiron with five different driving programs: Lift, EB "Auto", Autobahn, Handling und Top Speed.

The Chiron is shod with entirely new high-performance tires, once again developed by Bugatti together with its strategic tire partner Michelin. The tremendous forces on the tire at a speed of 400 km/h show what is needed. Each single gram of rubber is exposed to centrifugal force of 3,800 g, the result of acceleration some 3,800 times the force of gravity.

Bugatti uses special carbon ceramic brake discs made from carbon silicon carbide (CSiC). The brake calipers have a new asymmetrical design and can dissipate an extraordinary amount of braking energy. The front-axle brake calipers are each fitted with eight titanium pistons, with six titanium pistons on each caliper of the rear axle.
Technology
No fewer than 50 controllers manage the engine and transmission, the chassis components, the air conditioning and comfort functions. In order to ensure that a Bugatti remains compatible for many years with peripheral hardware and software which is continuously being developed, the processors fitted to certain controllers feature additional capacity for later programming.

The audio system installed on the Chiron is simply sensational. Developed exclusively for Bugatti by the "accuton" brand, well-known for its high-end equipment, this is the most luxurious sound system available on a super sports car. Among the equipment elements which are highly appreciated, Bugatti owners emphasize the telemetry function of their vehicles. With the telemetry system implemented on the new model, they will be able to carry out detailed preliminary investigations via the channels of the controllers. This can be important in order to make a precise assessment of any irregularities and the urgency of remedial action. In addition to the fast UMTS data transmission standard, the Bugatti Chiron is also equipped with WLAN (Wi-Fi).
Safety
The new design of the Chiron also meets all the latest worldwide safety standards. The Chiron boasts the most advanced airbag technology available, with a total of six airbags. Thanks to Bugatti's outstanding expertise in airbag design, it proved possible to develop an airbag that shoots through a carbon fiber housing. This is the case with the dashboard on the passenger's side and the seat housings.
