Audi cabin quality has long been among the best in the industry, and the A4's interior continues that trend. What distinguishes Audi interiors isn't just the use of high-quality materials, like real aluminum accents, but also the finish of the various trim pieces and the way they fit together well. Then you have the little touches, like a center armrest that not only slides forward and back, but also ratchets up and down.

In the past few years we've seen more attention to interior quality from brands like Cadillac (with its CTS) and Infiniti (with the G37), but the A4's cabin remains one of the nicest spaces in the class.

The front bucket seats are finished in standard leather upholstery. By comparison, many competitors like the 3 Series, Mercedes-Benz C-Class and CTS make do with simulated leather upholstery in base models. The A4's firm seat cushions provide good support and comfort, and the front of the cabin is big enough for my 6-foot-1 frame.

The backseat, though, is a little cramped. Just getting into it is difficult for taller adults, because the door opening isn't very large. Once seated, I didn't have much room to spare with the driver's seat adjusted for me, though indentations in the backs of the front seats provide some extra knee clearance. Taller people sit with their knees elevated some, which doesn't bode well for long-drive comfort. Still, it's more comfortable than the backseat of a 3 Series sedan.

The A4's trunk measures 12 cubic feet, which is similar to what competitors offer. The trunk has a nice rectangular shape for fitting luggage, and the split-folding backseat — previously standard but now optional like it is on the 3 Series and C-Class — creates a sizable opening for carrying longer items.
