No Audi A6 suffers for a lack of standard equipment--but many of them have hefty pricetags, thanks to the huge range of luxury and entertainment options Audi makes available.
On the base A6, there's a standard sunroof; power front seats; cruise control; leather upholstery; 17-inch wheels; tri-zone automatic climate control; power windows, locks and mirrors; tilt/telescoping steering; pushbutton start; AM/FM/XM/CD audio with a 6.5-inch LCD screen; and LED taillamps. Heated front seats are now standard, as of the 2014 model year.
Audi's Multi Media Interface (MMI) also is included on every A6. It's a roller-controller system that uses a knob and some hard keys to control navigation, phone, audio, and other functions. MMI's menus have been streamlined over the years, and the shortcut buttons are a welcome relief, but the system still can be a formidable few hours of learning before it becomes familiar. Like other automakers, Audi blocks all touch input from the screen, but there's a touchpad called MMI Touch that allows some secondary input. MMI Touch is a panel that doubles as both preset buttons for the audio system, and as a Palm Pilot-style scratch pad, on which drivers can write out letters to enter destinations or choose from the phonebook.
The next step in A6 features consists of the Premium Plus package. It adds a seven-inch color display; 18-inch wheels and tires; a CD changer (for anyone who still uses physical artifacts); HD Radio; real-time traffic data; front and rear parking sensors; and Audi Connect, and an in-car wireless data service through T-Mobile. Audi Connect taps that data stream to enable Google Earth navigation maps and traffic information. Audi's system also allows you to plan and send up to 50 destinations to the car's navigation system from a computer and Google Maps.
A6 Prestige models come at the top of the model line. And what's confusing is that you can add a $6,550 Prestige Package to them, which adds a lot of good stuff like distinct 18-inch wheels; four-zone climate control; adaptive headlights; LED interior lighting; a Bose speaker package; ventilated front seats; a power-adjustable steering column; cornering lights; and S-line cosmetic trim, including its own grille and bumpers. S6 models are only offered in Prestige trim.
Other noteworthy options include a cold-weather package; a Sport package with 19-inch all-season tires and five-spoke wheels; a xenon headlight package; and a Black Optic package with gloss black exterior trim and 20-inch wheels wearing summer tires. The best option? An awesome 15-speaker, 1300-watt Bang & Olufsen with tweeters that rise on startup.
Beware that you can easily load an A6 Prestige up toward the $70k mark--and that's about where the S6 Prestige starts.
