Apart from the frugal engine, Audi A6 Ultra come with other fuel-saving measure, chief among which a completely redesigned seven-speed S tronic twin-clutch transmission, which replaces the eight-speed multitronic CVT in four-cylinder model. It has s smoother operation with less noise and vibration and is also optimized for minimised internal friction which helps the efficiency.

The Ultra version of the A6 can be specified with all the goodies of the normal models including S-Line visual treatment and 20-inch wheels. So onlooker would never know this is actually an eco model and you bought it because you want to save a few quids on fuel.
