This top can be attributed to numerous features, a start-stop system. Playing a large role in the S8’s efficiency, however, is the new cylinder on technology. The system deactivates of the eight cylinders at low load, fuel consumption at moderate speeds by up to ten percent.

When the V8 into V4 mode, the active control (ANC) system is which uses targeted sound to eliminate unwanted In addition, active engine dampen vibrations.

Brimming technology: the chassis

The new Audi S8 pulls out all the stops when it to the chassis. The S8 comes standard a sport-tuned adaptive air suspension. The air suspension, which can give the one of three ride heights, perfectly with the dynamic also standard, that its steering ratio and boost to the speed.

The Audi drive dynamics system encompasses two systems as well as engine the eight-speed tiptronic and the sport The driver can vary the characteristic of chassis components between the auto, dynamic, individual and modes.

The wheels of the new S8 measure 9 J x 20 and are with 265/40-series tires. offers optional wheels up to 21 inches in diameter. The matt brake calipers on the front sport the S8 badge.

Engine

The new 4.0 TFSI from combines supreme power groundbreaking efficiency. It produces its output of 382 kW (520 hp) at 5,800 The twin-turbo V8 delivers a constant 650 Nm lb-ft) of torque to the crankshaft 1,700 and 5,500 rpm. Its fuel consumption of just liters per 100 km (23.06 US mpg) is lower than that of its

And compared to its predecessor, the new S8 consumes on 23 percent less fuel.

The 4.0 TFSI has a displacement of 3,993 cc, a of 84.5 millimeters (3.33 in) and a of 89 millimeters (3.50 in). As the member of the large Audi of V engines, the 4.0 TFSI has all of their features. The included angle the cylinder banks is a classic 90

As a space-saving measure, the chain to the four camshafts and the auxiliaries is at the rear of the engine.

The cylinder is made from an aluminum-silicon using a low-pressure chill process that achieves a standard of homogeneity. The high of silicon content makes the walls extremely resistant to The bedplate – a stable frame for the bearing bridges – further the block’s rigidity.

Weighing a 220 kilograms (485 lb) including all key parts, the V8 is very light.

almost every Audi the new 4.0 TFSI also follows the of downsizing: Forced induction displacement. This also perfectly with FSI direct injection. One twin-scroll turbocharger per bank compresses the fresh

From each pair of the exhaust ports lead to a manifold and the turbocharger housing; are not combined until immediately of the turbine.

The twin-scroll technology the exhaust gas flows from each other. The result is torque build-up at an early when accelerating from speed. Even at 1,000 the 4.0 TFSI reaches a torque of 400 Nm (295.02 lb-ft).

Special turbocharger in the V, “cold side” on the

The turbochargers and the common intercooler – an heat exchanger – are located in the V of the cylinder banks rather in the usual location outside to the crankcase. The cylinder heads a new layout, with the exhaust on the inside and the intake side on the This layout provides for dimensions and short gas paths minimal flow losses, and the 4.0 reacts immediately to the gas pedal as a Sophisticated insulation of the hot components, in the manifold, stabilizes the thermal in the inside V.

The fresh air system is mounted on the of the cylinder banks. Switchable in the intake ports induce a type of movement in the incoming The directly injected and intensively fuel cools the combustion

The 4.0 TFSI employs all the technologies Audi’s modular efficiency They range from the system to a wide variety of aimed at reducing friction.

technologies such as plate are used during assembly of the V8 at the plant in Györ, Hungary. The pins have a fine, carbon (DLC) coating.

The thermal management system a ball valve to disconnect the pump during the engine phase. Because there is no flow at all through the engine, the oil its operating temperature more shortening the phase in which frictional losses occur. The oil pump varies oil pressure in two

Attractive innovation: the cylinder on system

The most interesting in the new 4.0 TFSI, however, is the cylinder on system. It is activated at low to moderate loads, with the upper between 25 and 35 percent of peak or 160 and 250 Nm (118.01 and 184.39 lb-ft), on engine speed. Coolant must be at least 30 degrees (86 degrees Fahrenheit), third or higher must have selected and the engine must be at more than idle namely between 960 and 3,500

If these preconditions are satisfied, the closes the intake and exhaust of cylinders 2, 3, 5 and 8 on both banks. The V8 to run as a V4 with a regular firing (1 – 4 – 6 –7), but with only two instead of four being on each revolution of the crankshaft. in the active cylinders is increased the operating points are displaced higher loads.

The valves on the camshafts are closed by an enhanced of the Audi valvelift system Its sleeves can be slid sideways and have “zero-lift cams” as profiles.

Since these do not the cam followers as they rotate them, the valve springs the valves closed. At the same the engine management system down fuel injection and Four-cylinder status is indicated to the on the instrument cluster’s driver system display.

The fuel indicator bars turn and a text message is also

In the deactivated cylinders, the pistons to move because they are driven by the crankshaft. Before the close, the combustion chambers are filled with fresh This intake of fresh air pressure in the cylinder and reduces the needed to move the pistons – an important factor for increased

As soon as the driver presses down on the gas pedal, the deactivated cut in again. The return to eight-cylinder like the cylinder deactivation takes place so smoothly and that it is essentially imperceptible. The takes between just one and nearly four hundredths of a depending on the operating point.

The is accompanied by parallel interventions in the and the throttle valves, resulting in a drop in efficiency during the phase.

Audi has therefore a control logic that the movement of the accelerator and the steering by the driver. Cylinder deactivation may be if an irregular pattern is detected, for at a roundabout or when the car is driven on interurban roads. Cylinder lasting only a few seconds tend to increase fuel rather than reducing it.

more than ten percent at 100

The cylinder on demand system is to operate at all times, even in the S of the automatic transmission or the dynamic of Audi drive select. It the most fuel when the car is steadily at a moderate speed, as is the case on many main At around 100 km/h (62.14 the new technology reduces the fuel of the 4.0 TFSI by more than 10

In the standard NEDC test the increase in efficiency is around percent. If the effect of the start-stop that switches off the engine idling is added to this, the savings effect is around 12

Four-cylinder engines generally do not run as as classic V8 engines, and this is true of the new 4.0 TFSI when the on demand system is active.

these phases, the crankshaft produces higher torsional as a function of load and engine These vibrations penetrate the cabin in the form of solid-borne and the resultant airborne sound. The exhaust system also certain thrumming noises cannot be suppressed completely intelligent flap control.

The new active noise control technology counteracts unwanted by generating a targeted cancellation This principle is known as interference: If two waves of the same are superimposed, their amplitudes – the and troughs that determine the pressure – cancel each out. The amplitudes must be of the strength and the phases opposed by 180

In the Audi S8, four small are integrated inconspicuously into the Each of them registers the noise spectrum in its immediate From these signals the ANC unit computes a highly spatial sound image; on actual engine speed is obtained from the crankshaft In all of the previously calibrated zones in the system identifies disturbing it emits a precisely modulated sound.

The ANC must react quickly and accurately during the in which cylinder deactivation or takes place.

The cancellation is played through the speakers of the system. Because each and each speaker must a certain area, there is a fuzziness. The cancellation sound does not completely eliminate the noise, but reduces it until the occupants can no longer hear it. ANC is active, regardless of whether the system is on or off, or volume is set to soft or mute.

It works both of the available sound

Vibration killers: active mounts

Audi has developed a system in parallel to ANC: The engine mounts generate counter-oscillations to compensate for the second-order oscillations that occur four-cylinder operation. The key component is an oscillating-coil actuator. A flexible transmits the rapid strokes of the to the hydraulic fluid in the mounting, also absorbs vibrations the engine.

In the fluid, the counter-oscillations the engine vibrations and cancel out.

The control units for the engine mounts receive information from two sources. speed is detected by the crankshaft these signals are used to the precise phase and frequency of the signal. Acceleration sensors on the two mounts supply the data determine the amplitude necessary to out the vibration.

The active engine are also active at idle with all eight cylinders in In this case they eliminate engine excitation of the order.

Audi normally firm, sporty settings for its mounts. For many years Audi has therefore used electromagnetic mounts in certain and with certain engines. have two operating settings: idling, their soft keep disturbing noises and away from the interior; driving the damping is increased, in to suppress engine vibrations.

Drivetrain

highly flexible, eight-speed

The powerful 4.0 TFSI works with an extremely convenient and automatic transmission. The tiptronic’s speeds are tightly spaced, its high gear spread of between the shortest and longest reduces fuel consumption. starting off, the S8 accelerates while on highways it rolls with low, consumption-reducing

The eight-speed tiptronic impresses a high level of efficiency. One of the key to this efficiency is an efficient oil that reduces friction A hydraulic impulse storage enables the start-stop function.

For the restart, its oil volume is pressed the system by spring pressure – that the tiptronic is ready to in no time.

The dynamic shift (DSP) that controls the tiptronic features the automatic modes D and S. It uses high at low revs whenever possible, but quickly and flexibly when The DSP has access to the route data the standard MMI navigation plus. The uses this data to upcoming curves into its strategy – allowing it to avoid gear changes on meandering for example.

If the driver wants to he or she can use the paddles behind the steering or the lever on the center tunnel. It the thrust lever of a yacht, and the gear indicator is lit internally in The lever communicates with the purely electronically.

Gear are triggered by a brief tap of the lever, which it automatically returns to its position.

As in nearly every model with a longitudinal the eight-speed tiptronic is installed a special layout: The differential is in front of the torque converter.

The axle is then moved far – the advantages are a long wheelbase, a front overhang and a finely weight distribution. The rear differential in the quattro powertrain and the in the trunk also factor this balance.

The heart of the permanent all-wheel drive in the S8 is a self-locking center differential. The mechanical planetary gear sends 60 percent of the torque to the axle differential and 40 percent to the If one wheel slips, the differential most of the power to the axle the better traction.

Up to 80 percent can be to the rear wheels and up to 70 percent to the wheels.

Standard: the sport

The standard sport differential is a complement to the quattro drive. The rear differential distributes the in continuously variable proportions the rear wheels. It does using two superposition gears, of which comprise two sun gears and an gear and are engaged by means of multi-plate clutches.

They 10 percent faster than the shaft.

When the clutch it steplessly forces the higher of the superposition gear onto the The additional torque is drawn off of the wheel via the differential. In this way all of the torque can be directed to one wheel.

The difference between the wheels is Nm (1,327.61 lb-ft).

In fast the sport differential literally the sedan into the radius so the S8 corners as if on rails. The system any tendency toward oversteer or in the bud. Thanks to its short time – less than 100 – it works even faster the ESP stabilization system.

It is just as while coasting as it is under Control of the sport differential is into the standard Audi select system.

Complementing the differential on the front axle is vectoring. This software monitors whether the front wheel in a curve is about to In this case, it pulses the very slightly so that the wheel can transfer more to the road.

The system improves safety and traction.

Chassis

The S8 is the dynamic top model of the A8 family, the comfort of a luxury sedan amazingly sporty handling. Its chassis combines high with supreme stability and an ride.

All wheel control and many other components are of aluminum. The track measures millimeters (64.72 in) up front and millimeters (64.37 in) at the rear. The suspension comprises five per wheel – two transverse links on the plane, the support link and arm in the lower plane, and the track

The five-link design can handle and lateral forces separately. bearings are stiff in the lateral enhancing sporty precision; on the hand, the bearings are remarkably in the longitudinal direction. The axle are aluminum forgings; they the unsprung masses low.

The bar fabricated from a high-strength also saves weight.

A diecast strut brace enhances the rigidity of the front of the

The rear suspension of the new S8 follows the trapezoidal link principle, a design that ensures driving and comfort qualities. The two links are warm-hardened aluminum the wheel carriers are of chill-cast The top transverse links and the track are aluminum forgings; the stabilizer bar is a tube.

The struts act directly on the carriers. This allows a damping ratio so that the react sensitively. The developers also able to redesign the beam bearings to be more

The beam comprises two steel and lateral beams each; hydraulic bearings connect to the body.

Versatile: the adaptive air

The new Audi S8 comes standard a tautly tuned adaptive air which combines a high-end air with controlled damping and is used to level ride The air supply system is located in the of the car. The compressor works a pressure of 18 bar and fills a 5.8-liter vessel.

The large air capacity of the allows a soft characteristic and response even without an accumulator.

The adjustable two-tube absorbers inside the struts are by their low friction. Supplied data from a complex of sensors, the control unit the function of the shock absorbers to the conditions, the driver’s style, and the specified in the Audi drive system. Individual adjustments for wheel are made continuously by the via the control current for the damper

The driver can choose between different modes for the adaptive air in Audi drive select. modes changes the response of the absorbers and the ride height, is already ten millimeters (0.39 in) than on the Audi A8.

In auto and modes, the body is lowered by a 10 millimeters (0.39 in) once the S8 has longer than 30 seconds at a greater than 120 km/h mph). This increases and reduces drag, thus fuel. In lift mode, clearance increases by 25 millimeters in) from the standard ride so that smaller obstacles can be

The standard Audi drive system makes driving an more versatile experience. In to the adaptive air suspension, it also engine management, the eight-speed the dynamic steering, the sport the ambient lighting and the Audi pre basic safety system.

The can vary the function of these between the three modes auto and dynamic. Drivers can – certain limits – also an individual mode corresponding to own personal preferences. The fifth efficiency, promotes an economic style.

In this mode, drive select also the deluxe automatic air conditioning and the ACC stopgo function accordingly.

ratio: dynamic steering

steering is also standard in the S8. It is extremely precise and delivers feedback. It uses a superposition known as a harmonic drive to the steering ratio by nearly 100 as a function of driving speed and the in Audi drive select.

In traffic it is very direct; at speeds it is indirect to avoid constant steering adjustments.

At the limit, the dynamic steering the driver to cancel out understeer and by performing tiny steering autonomously. It also prevents the car pulling to one side when on surfaces with different of friction. The system needs time for such corrections the brake system needs to pressure at the wheels.

In many it does most of the work unnoticed by the driver.

The hydraulic dynamic steering receives its energy from a vane-type pump, which only as much fluid as is at any specific moment. The steering a rack-and-pinion construction, is mounted on the down low and far to the front. The track communicate the steering input directly to the wheels.

The Audi S8 equipped with a powerful, and lightweight brake system. All are internally vented; the front are also perforated. Stainless pins connect the cast-iron rings to the aluminum brake – a concept from sports car that prevents the transfer of peaks, reduces the risk of and reduces weight.

The front measure 400 millimeters (15.75 in) in the rear discs 356 millimeters in). Six-piston calipers matt black and sporting S8 are used up front, with calipers at the rear. Audi carbon fiber-ceramic discs anthracite gray calipers as an

They are particularly robust and and together they are roughly 13 (28.66 lb) lighter than discs.

The ESP stabilization system is of the art and works closely together the dynamic steering, the sport and the adaptive dampers. The ESP in the S8 includes a mode, in which the system significantly later. A trailer system and tire pressure are also standard.

Another feature, the auto release facilitates starting off on hills.

The of the S8 feature a five parallel-spoke typical of the S models from They measure 9 J x 20 and are fitted 265/40-series tires. Audi five additional wheels as four of which measure 21 in diameter. They come in a of attractive designs: polished, or two-color. Winter wheels are in 19 and 20 inch sizes.

Body

The body of the new Audi S8 is strong, and amazingly light. Its weight of 231 kilograms (509.27 lb) is a key reason for the sedan’s dynamics and efficiency. the standard quattro drive, the S8 has a weight of just 1,975 (4,354.13 lb).

The body in Space Frame (ASF) is roughly 40 percent lighter a comparable steel body. Its follows bionic principles. The comprises extruded sections and diecast parts of aluminum; the panels are joined to it using connections.

Like the bones in a all of the components combine optimal with low weight. The material is only where necessary and in a tailored configuration.

The most stage in the evolution of the ASF principle is construction with steel to improve crash safety. The of the S8 are made of hot-shaped steel. The are heated in a pass-through furnace to 900 degrees Celsius (1,652 Fahrenheit) and fed into the press thereafter.

The hot-shaped make up eight percent of the of the S8 body’s material matrix, most of the rest being – 35 percent panels, 35 percent components and 22 percent extruded Joining these wrought and individual parts is a high-tech Audi uses a wide of joining techniques – punch self-tapping screws, spot MIG welding, laser welding and bonding.

Laser welding is an domain. Because the seams high strength and rigidity, it can be to join large panels to the One area where laser is used is the aluminum invisible between the roof and the side of the

This is an area at the focus of all of precision during the design and assembly processes – the maximum for the outer skin is only 0.1 (0.004 in).

The ASF body is not lightweight, it is also very Its static torsional stiffness has by 25 percent versus the predecessor, was already a leader in the field. torsional rigidity has improved by 15 and lightweight quality – the relationship weight, torsional stiffness and – by 20 percent.

The ASF principle ensures low levels of vibrations and a tranquil free of disturbing vibrations or The windows of the S8 also contribute to with double/acoustic glazing Audi also offers and heated windshields as options; privacy glazing for the rear is another option.
