Together with the hi-fi specialists Bang & Olufsen Audi developed a sound system that sets new standards - for an unforgettable listening experience.

The developers have placed special emphasis on the calculation of the surround sound. For most audio sources such as CD or digital radio (DAB) only two output channels (stereo) can be programmed, but the driver of an Audi A8 and Audi Q7 even with these stereo sources can enjoy the benefits of surround sound. To calculate a special driver program from two channels, a surround sound with five channels plus subwoofer signal.

The Bang & Olufsen Advanced Sound System has a total of 14 speakers, each with its own amplifier. The speakers are mounted in sealed boxes, then for each speaker always guaranteed the same conditions. Another advantage of the closed housing is the minimized noise emission in the environment of the vehicle, which in turn allows for maximum privacy in the car.

The 3-way front system is a 165-mm woofer (at Audi A8: 140-mm woofer): in a box in the front and a 80-mm mid-(90-mm mid Audi A8) Doors formed. The treble is performed by two 19-mm Acoustic Lens speakers that extend from the instrument panel. Center as a 80-mm cone speaker (at Audi A8: 70-mm).

The 2-way system back is ever a 140-mm woofer (for A8: 133-mm) and put in a box of 25-mm tweeters in the rear doors. The bass is played by a giant 20-liter subwoofer with a 200-mm woofer. For surround playback of the sound system is powered by two 80-mm broadband speakers: completed in the headliner (A8 90-mm wide-bang surround speakers).

The active sport differential distributes torque from the engine in continuously variable proportions between the rear wheels.

Targeted control of the power flow enables the car to steer even more spontaneously and directly into bends, and produces a far more robust directional stability.

Depending on the steering angle, lateral acceleration, yaw angle, road speed and other signals, the control unit calculates the most suitable distribution of torque to the wheels for every driving situation.

When the steering wheel is turned or the car is accelerated in a bend, power is redirected in a controlled manner to the outer rear wheel. This has the effect of “forcing” the car into the corner so that it accurately follows the angle of the front wheels.

The difference in tractive force between the left and right wheels exerts an additional steering effect, so that the usual corrections by the driver at the steering wheel are no longer needed. Understeer is completely eliminated. Active torque distribution is based on an entirely new design principle for the rear-axle differential.

So that the new high-tech unit can also divert torque to the outer wheel of the axle, which revolves faster than the inner wheel when cornering, the classic rear-axle differential has been equipped with superposition stages on the left and right, each with a multi-plate clutch running in an oil bath. The clutches are activated by an electro-hydraulic actuator. The superposition stage rotates ten percent faster than the half-shaft that normally drives the wheel; the two components can be coupled by the multi-plate clutch. If the clutch is engaged, the wheel is accelerated by the superposition stage, which is running at a higher speed, and thus receives an additional torque input.

The differential reduces the tractive force reaching the opposite wheel accordingly. In most driving situations, almost the complete input torque can be diverted to one rear wheel in this way. The maximum difference in torque between the wheels is 1,800 newton metres.

As a car manufacturer, we can never claim to have a truly positive impact on the environment – and nor should anyone else in the automotive industry. But what we can be certain about is that the billions of pounds we’re investing in responsible technologies over the next decade will place Audi at the forefront of efficient motoring and manufacture.

The principles of constant innovation at the heart of Vorsprung durch Technik already place Audi in a strong position. Technologies such as our lightweight space frames, efficient TDI engines and our waste-reducing manufacturing processes all serve to cut CO2 emissions. And we’ve been doing this for years – we’ve improved our cars’ efficiency by over a third during the last 20 years, and by 2012 we pledge to reduce the emissions of our vehicles by a further 20 per cent.

We’re continuing to work hard today to create a clean driving tomorrow and have a number of very exciting developments to offer our customers over the coming years. Read on to learn more about our commitment to reducing our, and your, impact on the environment.

In the UK

Whilst our colleagues in Germany are doing everything they can to make our cars more efficient, at Audi Head Office in Milton Keynes we are also committed to reducing waste.  A lot of what we do isn’t very innovative, you probably recycle paper and switch off unused appliances at home, but it does make a significant difference to our carbon footprint.  On top of this, by investing in technologies like intelligent lighting and video conferencing we are able to work efficiently without compromising our business standards.  And by joining forces with Audi UK’s franchise operation to minimise waste, we are generating tangible environmental benefits across the whole of the network.
