This is a still a compact sedan, yet the new design makes great use of the floor space. Every interior dimension is larger, but it's most obvious in the back seat, where taller passengers will find a bit more room to stretch their legs. There's room in back for three, with three-point harness at all positions, but average-size adults will feel much more comfortable with only two. The front seats adjust to accommodate people in the six-foot, five-inch range, and the view out is nearly unobstructed in every direction.

The theme inside the A4 is cool and efficient, as it is in Audi's other sedans, and not deliberately snazzy in fashion of the TT. Materials look and feel richer than those in many cars in this price range, and trim matches flawlessly. A thick, grippy, leather-covered steering wheel and shift lever are standard, with a choice of fabric or leatherette (vinyl) upholstery. The cabin beltline is edged with aluminum in the 1.8T and real wood in the 3.0.

Switches could be larger, yet those most frequently adjusted, including stereo volume, are large enough. After a bit of familiarization, everything in the A4 is easy to find with minimal distraction, and nearly all temperature, ventilation and stereo adjustments can be completed with buttons on the steering wheel hub. Audi's red and white gauge lighting, its warning lights and LEDs, are among the sharpest, most readable going. Its radial sunroof switch is the best; turn it a quarter, half or full turn and the roof opens a corresponding distance. Flow-control switches on each dash vent are illuminated. Wipers make a final sweep several seconds after the washer button is released, cleaning droplets blown back up the windshield. We found nothing to gripe about during a long drive through Vermont's Green Mountains, with the possible exception of the seats. They are comfortable and supportive in nearly all circumstances. Yet a sedan this good should have buckets with more side bolstering to keep occupants firmly in the center.

The 2002 A4's trunk is among the largest in the class (13.4 cubic feet, compared to 10.7 in the BMW 3 Series and 12.2 in the Mercedes C-Class). Moreover, the lid swings high and backs for easy access. There are four tie-down hooks in the carpeted floor and a removable grocery net. The cold-weather package includes a nylon ski sack that allows snow skis to slide through the trunk and into the cabin without leaving a damp mess.
