7 years and still like

Vehicle: 2006 Audi A6 4.2 quattro 4dr Sedan AWD (4.2L 8cyl 6A)

I've owned a lot of cars. Many of which I cycled through as I got bored of them, or they just started to under perform and cause issues. I purchased this A6 with 5K on the clock and it currently has 65K. I do pamper it, but it returns its pampering with flawless performance with an engine roar that sounds better than the day I got it. Oh yeah and 7 years and there is not one bit of rust.

What a porsche 911 aspired

Vehicle: 2006 Audi A6 4.2 quattro 4dr Sedan AWD (4.2L 8cyl 6A)

I'm amazed at how it sticks to rails as I corner. The heated steering wheel, racing seats, electric sun shades are all nice, but it is the performance in an understated sedan that impresses me most. When I look at how this model is rated by everything from The Robb Report to Road & Track against competitors many times its price, I'm grateful to have found this hidden gem. Yes it needs 9 quarts of oil but it's built like a rock. Only problems have been buttons wearing out and headlights leaking, easy fixes. Rear air bag needs work too.

Terrific cpo purchase

Vehicle: 2006 Audi A6 4.2 quattro 4dr Sedan AWD (4.2L 8cyl 6A)

I had finally outgrown my e36 m3 and decided to get a more austere sedan. I shopped Infiniti, BMW and Audi. I picked up a CPO 2006 A6 and couldn't be happier with it. The car drives wonderfully, although the V8 is a little thirsty if you keep your foot in it. I expected that though. The car is built very solid, and offers 90% of the 5er performance, but with a bit more comfortable ride. I have non-sport suspension btw, and look to change that at some point, mainly to minimize the 3" wheel gap (Toyota?). Otherwise, the car is gorgeous, and I look forward to keeping it for quite awhile. I think an A6 is a terrific CPO purchase, the extended warranty could come in handy (hopefully not).

Vehicle: 2006 Audi A6 4.2 quattro 4dr Sedan AWD (4.2L 8cyl 6A)

This car was 23 months and had 15,000 miles when I bought it in 10/08. The car is a dream. It rides better and is more comfortable than any car I've ever had. It can float down the highway or play on mountain curves, whatever suits you. Even with the 8 cylinders, I get 28 mpg on the highway. In town is rough at 15, but I expected that. I like the fact that it has all the features of its better know competitors, but you don't see as many of these on the road. If you see one for a good price, grab it before it runs away. The secret is getting out, Audi rocks.

Vehicle: 2006 Audi A6 4.2 quattro 4dr Sedan AWD (4.2L 8cyl 6A)

I am very impressed with my Audi A6. We opted for the 4.2L V8 and have been very pleased with the performance. We looked at BMW and Mercedes, but there was no comparison with the luxury, technology, and of course the Quattro AWD. The car sticks to the road like glue in wet or dry conditions. The S- Line package makes the suspension so responsive that it is a pleasure to drive each time. The MMI is easy to use and the interior ergonomics fit like a glove. I'm sticking with Audi.

Vehicle: 2006 Audi A6 4.2 quattro 4dr Sedan AWD (4.2L 8cyl 6A)

The car is tight, responsive and handles well. However, the engine is a little loud. The drawback to this vehicle is the brakes which are much too touchy. Difficult to glide to a smooth stop. The controls (radio,t emp, phone, navigation) are very handy and easy to use.

Full 2006 Audi A6 Review

What's New for 2006

Two new A6 models debut this year, a 3.2 Avant (wagon) version and a front-wheel-drive 3.2 sedan with Audi's CVT continuously variable transmission. An S-line package is now available for both the 3.2 and 4.2 sedans and features a sport suspension, 18-inch wheels with summer tires and upgraded trim. Bose surround audio is now standard on the 4.2 sedan, while the Avant and 4.2 receive standard heated front seats. New options this year on the Audi car include adaptive cruise control and an adaptive air suspension system. All models get wood trim and a tire-pressure monitor standard. Finally, the A6's Bluetooth system is now Treo Smartphone-compatible.


The A6, Audi's midsize luxury car, has been around since 1998. The first-generation car, though offering all-wheel drive and a fantastically trimmed interior, was increasingly outclassed in its later years.

A full redesign brought forth the second generation Audi A6 just last year. The suspension is comprised of an upgraded four-link front suspension and a self-tracking, trapezoidal-link rear setup borrowed from the A8. Audi reports that torsional stiffness is up by more than 34 percent over the previous A6. All of these upgrades were designed to help smooth out unwelcome body roll while turning tight corners and keep the wheels firmly planted on the road.

In keeping with tradition, the interior of the Audi A6 features a wealth of aluminum, leather and wood. The wood in particular is some of the most gorgeous you'll find in this class. An Advanced Key feature allows drivers to keep the key on their person and simply hit the start button when entering the car, instead of fumbling for the ignition. Other creature comforts include optional voice control for the Bluetooth hands-free cell phone system; an audio system with available Bose Surround Sound; and an optional DVD-based navigation system.

This year Audi has added a station wagon version to the A6 line, as well as a front-wheel-drive model with a CVT automatic transmission. The 2006 Audi A6 has plenty to offer buyers who crave luxury (in fact, no one beats Audi in this area) and like the idea of owning an all-weather vehicle. Though the standard direct-injection V6 is still a little short on low-end torque for our taste, the available V8 is as smooth and potent as any eight-cylinder in the class. Serious enthusiasts are still apt to prefer the near telepathic steering of the 5 Series, but the majority of drivers will be quite content with this Audi's combination of luxury, sporty handling and comfortable ride quality.

Body Styles, Trim Levels, and Options

The midsize Audi A6 is sold in sedan and Avant (wagon) body styles. Sedans come in 3.2 and 4.2 trim levels (which correspond to the engine found under the hood), while the wagon is 3.2 only. Standard features on the 3.2 sedan include 16-inch alloy wheels, wood interior trim, leather upholstery, 12-way power front seats, dual-zone automatic climate control, a 10-speaker stereo with a glovebox-mounted CD changer and a tire-pressure monitor. The 3.2 wagon adds 17-inch wheels and a sunroof. The top-line 4.2 sedan provides HID headlights, upgraded leather upholstery and driver memory settings. The S-line package will give you a sport suspension, 18-inch alloy wheels with performance tires, gray birch wood inlays, headlight washers and unique bumpers and grille. Other options include adaptive air suspension, rear parking sensors, adaptive cruise control, a DVD-based navigation system and voice recognition technology.

Powertrains and Performance

The Audi A6 offers a standard 3.2-liter V6 and an optional 4.2-liter V8. The V6 is rated at 255 horsepower and 243 pound-feet of torque, while the V8 bumps up to 335 hp and a torque rating of 310 lb-ft. The sedan is available with either engine, while the wagon comes with the V6 only. The 3.2 front-wheel-drive sedan has a continuously variable transmission (CVT) instead. All other A6s come with a six-speed automatic transmission and the quattro all-wheel-drive system. While both transmissions work well, serious enthusiasts may miss having the option of a true manual transmission.


The A6's standard four-wheel antilock disc brakes include BrakeAssist and Electronic Brakeforce Distribution. Stability control is also standard as are anti-whiplash front head restraints, front-seat side airbags and full-length head curtain airbags. Rear-seat side airbags are optional. NHTSA has not crash tested the A6, but the Audi car performed admirably in IIHS testing, earning the top rating of "Good" in both front-offset and side-impact tests.

Interior Design and Special Features

The 2006 Audi A6 offers one of the best interiors of any midsize luxury sedan. Besides offering standard leather and wood inlays, each cabin is filled with supple, high-quality materials. If you bought an A6 for the sake of luxury alone, you wouldn't be disappointed. All models come with the Multi Media Interface (MMI) vehicle management system, whose 7-inch display is integrated with the 10-speaker Bose stereo and the optional navigation system. In practice, it's much easier to use than BMW's iDrive or Mercedes' COMAND and helps minimize cabin clutter.

Driving Impressions

Even with direct injection, the V6 is light on low-end torque, though most buyers will find the acceleration acceptable. The V8 is more satisfying with its deep reserves of power and exceptionally smooth demeanor. While the handling is softer than BMW's 5 Series or Infiniti's M35/M45, the Audi A6 provides an excellent ride around town along with predictable reflexes and precise steering through turns. Additionally, its quattro all-wheel-drive system affords it prodigious grip around turns that makes spirited driving that much more fun, while providing all-weather capability.
