The S6 Avant completes the sprint in 4.6 seconds. Combined fuel economy is an impressive 30.7mpg in the Saloon and 30.1mpg in the Avant, the equivalent of 214 and 219 grams CO2 per kilometre, respectively.
This efficiency is due in large part to the cylinder on demand (COD) system, which only activates four of the eight cylinders when under part load.
Standard equipment in the new Audi S6 and S6 Avant includes quattro permanent all‑wheel drive incorporating the sports differential and the adaptive air suspension, which lowers the body by 20 millimetres. Matt black brake calipers grip the front discs mounted behind the 19‑inch wheels.
The sinewy style of the exterior is echoed in the car’s spacious interior, which in the Avant is combined with a 565-litre load bay that can be expanded to 1,680 litres. Every detail attests to an uncompromising approach to quality, and the elegant colours and carefully selected materials emphasize the premium class ambiance.
A new Lunar Silver upholstery and headlining colour choice for S line versions, which have until now been available finished exclusively in black, is one advantage offered by the new model, as are subtle detail enhancements, including an upgrade from dual-zone to deluxe four-zone climate control, new gear lever designs and additional chrome detailing.
Technology aficionados will also appreciate the upgraded infotainment options, which include new versions of the top-of-the-line MMI navigation plus and Audi connect elements. Based around an eight-inch retractable colour monitor, MMI navigation plus is available as an alternative to the standard navigation system. It now uses an even more powerful Tegra 30 graphics processor from Audi’s partner Nvidia, and includes MMI touch, which enables the driver to scroll and zoom in lists and maps via a touchpad. Audi connect now brings tailored Internet-based services and new media streaming apps to the car via the latest LTE high‑speed data transmission standard for ultra-fast 4G click-through and download functionality.
