2005-2008 Audi A6 and allroad quattro: Road Test

The 3.2 V6 provides strong pull from a stop and ample highway passing power, though around-town response is at the mercy of sometimes-tardy transmission downshifts. Potent 4.2 V8 quicker still, with satisfying power across the rev range. Some testers complain of imprecise throttle action away from a stop with both engines. Audi quotes 0-60 mph of 7.1 sec for 3.2, 6.0 for 4.2. All engines remarkably refined, though V8 snarls surprisingly at high rpm. In our experience, fuel economy was a bit disappointing. In an even mix of city/highway driving, test 3.2 averaged 16.1 mpg, test 4.2s averaged 14.7-16.3. Audi recommends premium-grade fuel for all models. The A6 strikes a fine ride/handling balance, though it is a bit firm for a luxury vehicle. Sharp bumps can jolt, especially with the 18-inch tires, and sometimes with the 17s. There is virtually no highway float or wallow. The handling is among best in the class. It exhibits impressive composure in corners and little body lean. Steering has satisfying weight and accuracy. Audi's AWD provides great grip and poise on all surfaces. The brakes deliver smooth, short stops. Inside, the A6 sports contemporary design with high-grade materials and assembly--the envy of many a luxury-car company. The MMI control system easier to use than BMW's complicated iDrive, but is still a distracting alternative to conventional switchgear. Other controls are logically placed, simple to use, but the CD changer is in glovebox, out of the driver's reach, and there is no slot in the dash. Cabin impressively absent of wind noise, even at high speed. Road noise is subdued. The front seat offers vast leg room and ample head room. The seats are comfortable, firm, and supportive. Visibility is excellent in all directions. The rear doors open wide to nicely contoured, not overly firm seats. Audi provides adequate knee room, even behind taller front passengers. Toe room is snug, and head clearance is good for those up to 6-ft-1. The sedan's trunk is long and fairly wide; the strut-type hinges don't intrude and there are handy grocery hooks. The rear seatbacks fold 60/40, providing greater utility. The wagon offers SUV-like room. All doors have generously sized map pockets, but interior storage is otherwise subpar.

Value for the Money
The A6's luxurious interior detailing, capable quattro AWD, overall refinement, and cool sophistication earn it a place on any luxury shopper's list. Negatives include the way the MMI system complicates some control functions, sometimes frustrating throttle response, and Audi's reputation for malfunctioning electronics.
