Sporty components and high-tech systems also play the leading role in the list of optional extras. The radar-controlled adaptive cruise control, for instance, has a decisive advantage over conventional cruise control systems: this intelligent system continually measures the distance from the vehicle in front and correspondingly adjusts the car's own speed by manipulating the accelerator and brakes. Audi adaptive light provides a dynamic source of light when cornering, pivoting the headlights to cast their light into a bend.
Audi parking system is an acoustic rear-end parking aid, and its plus version supplies acoustic and visual feedback on clearance at both the front and rear, via the MMI display; finally, the advanced version activates a rear-view camera. The HomeLink garage door opener with programmable remote control opens garage doors and gates, but can also be used to control security and lighting systems.
There are numerous options in the infotainment area, such as a BOSE sound system with 5-channel surround reproduction, 13 speakers and 270 watts combined output, digital radio reception (DAB), analogue and digital TV reception, navigation system with DVD (dynamic route guidance with RDS-TMC), a speech dialogue system, and Bluetooth mobile phone provision and Bluetooth car phone.
There are optional inlays in matt brushed aluminium for the door trims and instrument panel which contribute to the individual look of the interior.
Alternatively, customers can order grey birch wood or mid-brown walnut for the door trim, instrument panel and centre console with an aluminium-look surround.
From the second half of the year, there will be the option of power-assisted closing, which helps by completely shutting doors that are not properly closed; it also incorporates electrically operated child safety catches for the rear doors.
The S6 Avant can be supplied on request with an automatically operated luggage compartment lid that is opened and closed electrically. The lid can be opened via a button on the car key, a button in the driver's door trim or the soft touch button on the lid itself. The luggage compartment lid, which includes lid closing assistance, is closed via the button on its inside; this button can also be used to program the desired opening angle.
18" winter wheels are available with various tyre sizes, as is a spare wheel with a full-spec tyre. The optional tyre pressure monitoring system monitors the tyre pressure and temperature of each the four wheels during the journey, including on factory-fitted winter wheels. The inflation pressure and temperature of the wheels can be displayed individually in the MMI.
Side airbags for the outer front seats complement the safety functions of the continuous Audi sideguard head airbag system and the side impact protection in the doors.
An electrically operated sliding/tilt roof of tinted glass with adjustable sun shield is available optionally, as is a solar sliding roof with integral solar cells which generate energy to run the ventilation blower even when the car is parked, in order to reduce the temperature inside the car. Roller sun blinds are available for the rear window (electrically operated for the saloon, mechanically for the Avant), and also for the rear door windows if desired.
The outer rear seats can be heated as an option. The S6 also offers the optimised feature of an auxiliary heating/ventilation system for full climate control of the interior. The additional comfort of a pre-warmed interior means that it is no longer necessary to de-ice the windows in winter. In the summer, fresh-air circulation in the vehicle serves to reduce the temperature in the passenger compartment. The auxiliary heating and ventilation is activated either by way of the pre-select function on the on-board MMI "Climate Setup" menu or via remote control from a distance of up to 600 metres away.
On top of this, customers have a wide range of other optional extras to choose from.
