As a luxury and sports take into account the two major characteristics of the Audi A8 listed since 2003, has been successful in the European luxury of place among the ranks of large cars, now four-ring logo can be said to have been successful in the field of luxury cars opened the one different from the traditional territories , Sports and luxury models have become increasingly popular models. Recently, Audi announced a its highest level of the A8 luxury cars, sports, the new S8. Estimated the public sale date in mid-2006, based on prices for 97,600 euros (equivalent to about 950,000 yuan RMB).

Engine power

S8 new impetus from an extraordinary V10 engine, why do we use "extraordinary" to define the V10? Because it has come from an F1 car engine on the advantages and performance capabilities. Lamborghini as Audi, a subsidiary, despite the V12 engine has very strong advantages, but in recent years Lambo also launched the V10 models Gallardo, and in cooperation with the Audi, from the gradual growth in international competitions, In the original inheritance of the traditional V12 engine, more laid a V10 engine's excellent performance capabilities. Compared with the V12 engine, V10 engine more compact, operates in a more gentle, less vibration.

450-horsepower V10, is the second generation of Audi V-engine, 90-degree angle, 90 mm opening angle of the engine, the most critical is that this is still a Lamborghini Gallardo from the engine, bore from 82.5 mm to expand 84.5mm, 92.8mm trip, 5.204 L of displacement. Manufacturing in Detroit, used a technique known as flat-panel structure, an increase of aluminum casting the strength of the Pistons.

The resettlement in the spark plug, use a 18 degree angle so that the ignition turned into a 72 degree angle, the benefits of doing so is to slow down the Pistons in the top of the inert and improve the overall precision engine. Camshaft in the resettlement, the first by a continuous variable-valve technology section, based on intervals of 42 degrees, and then, the real engine in operation, according to engine load to the regulation of this real-time perspective. In between the cylinder and the cylinder, using a special filling techniques to enhance the engine's output capacity. 40 valve engine, a maintenance-free chain and the main axis connecting to ensure that the barrier has no power to pass on each valve.

S8 of the V10 engine, the oil road, using FSI direct fuel injection technology, enhancing the engine's compression ratio to 12.5:1, the injection pressure to 100 Bar (equivalent to 100 atmospheric pressure). Two-stage electronic automatic adjustment of the suction I can sense the engine needs air, take the initiative to change the volume of air inhaled. In Le Man24 hour endurance race on, Audi R8 was the first to use all of the above technologies, competition results have no doubt Hao proved that the FSI engine in the same type of engine technical advantages.

This is awesome V10 3.5 of the torque and power output capacity to 7,000 at the maximum 450 horsepower, in 3500 to be 540 N m at the maximum torque, can be as low as 23 to 90 percent of maximum torque, throttle response capacity , Can almost be said to be instantaneous, followed by the tail is the elegant sound waves, vehicle dynamic extraordinary.

As a luxury sedan, the introduction of such a high-powered engines, the results are indeed alarming. 100 km speed up the results in 5.1 seconds, top speed electronic speed was 250 km / h, such as third-generation engine, the ideal fuel consumption of 100 km down to a 13.5 L / 100 km. Let us have a concern about the Thrust-Weight Ratio engine, 450 horsepower, 1,940 kg of promoting the vehicle, reaching 4.31 kg / hp, can be called a sports car the ideal ratio.
Gearbox and transmission mechanism




S8 is also a typical Audi cars, used quarro four-wheel-drive the entire structure, the combination of 25 full-drive technology and from the Lambo engine technologies, to ensure the S8 under various road conditions are the best Grip. Central differential was installed in the horizontal drive shaft, Qian Houlun responsible for the regulation of power output ratio. Under normal circumstances, the front wheels will be 40 percent of the force, rear-wheel-60%. Once there is a change in road conditions, the rear wheels will be the largest 85 percent of the power output, if a round on a slippery phenomenon, electronic differential control system, corresponding to the four-wheel braking to ensure a balanced grip.


S8 adopted a new six-speed tiptronic CVT me. The gearbox, on the one hand can effectively expand the space vehicle, on the other hand guarantee the 450-horsepower for the transmission system is not wasted. As a CVT systems, to the greatest degree of the engine's power output and the load on wheels of a coupling, in the campaign mode, the engine can increase the transmission speed, engine power play to the extreme. At the same time, S8 and opening up under the steering wheel shift Bogan, for the manual transmission provides a complete freedom of driving.

Audi S8 in the beginning of the design, it will be lighter on a first-class status, V10 engine control was in the weight of 220 kg, compared with competitor's engine light of the full 20 kilograms, higher-quality transmission shaft, Lowering the load of the engine at the same time, improved throttle response capacity. Battery and energy management have been concentrated in some luggage warehouses, to balance the ratio of vehicle weight.
Chassis

Quiet chassis, without affecting the speed, S8 This is the biggest characteristic of the chassis.

As a sport-luxury sedan, a campaign to ensure that their properties, but also the assurance that the comfort, the chassis on the work must be very important, which is due to S8 all the unique design concept. All the full use of aluminum alloy control arms manufacture, the front suspension on a four-point connecting structure, after the hoisting of the ladder on the adaptive structure.

S8 development of the use of a special version of the initiative campaign to air suspension, but as a necessary accessory assembly elections, its greatest feature is hoisted by compressed air to provide the necessary buffer, and this function can be controlled by the electronic control unit, the hoisting of the Hardness and itinerary will be carried out timely control, change, the role is to improve comfort, safety and ability to respond to more direct manipulation. Such a set of air suspension, divided into a total automatic, comfort, dynamic and upgrade the four states, for example, in body weight changes, the system will take the initiative to raise the body height; once the adjustment to the campaign mode, the system will also reduce the body height of 20 mm . In guarantee that the vehicles through capacity at the same time, the system will be 125 mm to 95 mm range, according to take the initiative to speed the adjustment for body height and improve high-speed stability.

Wheels, a 20-inch wheels, the 265 mm wide 265/35 R20 tires, brake disc or even a 18-inch large-size ventilation ceramic brake disc carbon fiber, 8 piston calipers using two-way structure, with excellent thermal insulation characteristics , Said a statement on the life of 300,000 km, appearance on the use of titanium silver, very Chutiao. From the former standard of 385 mm, after 335 mm diameter brake discs, one can see how S8 with ferocious power.
Design

A8 appearance on the use of the package, but in aerodynamics have done a lot of improvements, there is a simple lightweight surrounded by the large-size large, 20-inch wheels, cellular-style grille, four chrome exhaust pipes highlighted the first . All-in-one front, A8 and the new surface, no big difference in size but have great differences, this is only the benefits of improved engine air inhaled fluency to ensure that necessary to have enough The air to the engine to use.

Internally, filled with the dynamic, elegant circumstances of the pursuit of the car, seen everywhere in S8 logo, door handles, steering wheel, carpets, are constantly remind motorists that this is an outbreak of the sport-can cars. Top of the leather wrapped steering wheel, the best hand, the central control panel installed on the Audi's MMI multi-media control center, to facilitate the additional features of the vehicle control is, of course, does not affect the enjoyment of driving pleasure at the same time.

Safe

Did not compromise safety, Audi has always been the most attention to the security of one of auto enterprises, the same as the theme for the movement of the S8 also apply.

The first is high-performance braking system, may be such a high standard braking system, in other homes will be used in pure movement and even track-level sports cars, but Audi, however such technology to marry under the S8, on the surface can Safety seriously. Electronic control, Audi vehicles using dynamic posture detection management system to ensure that the vehicles in the event of spin the first time to intervene and improve security. In addition, there are pre-tension in the three-point seat belts, the former two, four side, such as head air bags to ensure that the final one of the passive safety performance.

The latest LED light source for the lighting system will start during the day in the state, reminded the opposite to the attention of cars. So far the main headlamps using the most bright xenon lights, and with the initiative to function, support drivers improve the visual corner of the attention; taillights is used to highlight the LED lights, reducing the risk of collision accident occurred at the same time, show The Audi on the importance of new technologies and applications.

Accessories

As a luxury sedan, the election certainly has many accessories to meet the distinguished owners can enjoy the enjoyment of the highest specifications, no keys into the system, one-button ignition, the confidentiality of noise dark glass, DVD electronic navigation system, with the central control unit Hand back the pillow, with support memory function waist massage chairs, advanced hi-fi from Bang & Olufsen of the 1100 W power 14-channel audio-visual system, everything is good service.
