Apart from its variety of body styles, drivetrains, and safety systems, the 2009 Audi A4 offers a host of standard and optional features that are among the best in its class.
Standard features on the A4 include the usual power accessories, an AM/FM/CD player, and air conditioning. Motor Trend adds that “leather will be standard.”
Moving smartly up the pricing scale, the options available on the Audi A4 can quickly run up its sticker. Among the audio options, Motor Trend adds, is “a choice of Bang & Olufsen stereo systems, including the excellent 14-speaker setup we sampled, plus a six-disc CD changer and iPod connectivity.” Of the upmarket sound systems, Edmunds says, “We have no complaints.” Bluetooth connectivity is also available, as is Sirius Satellite Radio.
A cutting-edge feature in the A4 that shares some traits with other German sedans is Audi’s MMI (Multi Media Interface), which commands available audio, navigation, and climate control systems. “It makes [BMW’s] iDrive seem like a cruel joke,” Edmunds reports. “In the A4 and other Audis, a knob and buttons on the center console are used to navigate menus and make selections that appear on a dashboard screen,” Cars.com explains, adding that “MMI can be tedious to use at times, but Audi does provide secondary controls for the air conditioning system.”
A keyless entry system is offered on the new 2009 Audi A4. “It can—like most cars in this segment—recall radio presets, exterior mirror positions, and interior-and-exterior lighting preferences on approach and egress,” Cars.com reports. “But programmability now extends to many more ancillaries, such as deactivating the auto-up feature on the rear windows or turning down the intensity of the steering-wheel warning vibes when the new lane-monitoring option thinks you're veering.”
Popular Mechanics also mentions the Audi’s more exotic options, like “active cruise control, lane monitoring and collision warning—not to mention Audi side assist, a radar-based system that warns against vehicles approaching from the rear three-quarter view—often a potential blind spot for drivers.”
