Audi A4 - What the Auto Press Says

The 2010 Audi A4 ranks 7 out of 15 Upscale Midsize Cars. This ranking is based on our analysis of 18 published reviews and test drives of the Audi A4, and our analysis of reliability and safety data.

Redesigned just last year, the Audi A4 is a viable alternative to the BMW 3-Series. Buyers looking for a sporty entry-level luxury sedan should test drive an all-wheel-drive A4 before making their decision.

The Audi A4, redesigned from the wheels up for 2009, enters the 2010 model year with no significant changes. It remains a fun car to drive, with sharp handling and a firm stance courtesy of its Quattro all-wheel-drive system (optional, but Audi says more than 80 percent of buyers opt for it). Audi's adjustable suspension, which allows the driver to electronically change the car's tuning for aggressive cornering or quiet commuting, is particularly well-reviewed. The combination, Consumer Guide says, means the A4 "adeptly balances around-town maneuverability with sporty road manners."

Shoppers should note that the A4 is the largest sedan in the midsize class - which means it's an opportunity for some buyers of more expensive luxury sedans (like the Lexus GS) to downsize and save some money. However, the A4's price can climb north of $40K with all of the options -- and you'll want most of them.

Audi is known for some of the best interiors in the automotive businesses, and the A4 offers an excellent example of why.
Other Cars to Consider

Those looking for an athletic sport sedan would do well to compare the A4 to the BMW 3-Series, which some say out-hustles and out-handles Audi's car. Those for whom All-Wheel-Drive is essential might want to consider an AWD Infiniti G37, which offers an exceptional balance of luxury and performance. The Acura TL, in SH-AWD trim, is another excellent AWD option.
Audi A4: The Details

The 2010 A4 comes as a sedan, an Avant wagon, or the more off-road-oriented Allroad wagon, in 2.0 or 3.2 trim. We review the wagons separately. Buyers should note that the A4 Cabriolet convertible has been dropped from the lineup, with a sportier 2010 A5 Cabriolet taking its place.
