The 2009 Audi A4 is a four-door compact luxury vehicle available in three body styles: sedan, convertible (Cabriolet) and wagon (Avant). The base A4 trim level is the sedan-only 2.0T FrontTrak, which comes with front-wheel drive and a continuously variable transmission (CVT). Next up is the AWD 2.0T Quattro, which is available in all three body styles. The 3.2 Quattro trim is limited to the sedan and convertible. Note that the convertible's standard and optional features are listed separately below due to its previous-generation platform and equipment roster.Standard features on sedans and wagons are clustered into three packages -- Premium, Premium Plus and Prestige -- that can be specified across the lineup except for the base Premium package, which is unavailable with the 3.2-liter Quattro. Premium models include 17-inch wheels, foglamps, a sunroof, air-conditioning, power front seats, leather upholstery, cruise control, a split-folding rear seat, Audi's MMI system and a 10-speaker CD audio system with a subwoofer, satellite radio and an auxiliary audio jack.
The Premium Plus adds bi-xenon headlamps, LED daytime running lights, auto-dimming side and rearview mirrors, Bluetooth phone connectivity, three-zone automatic climate control, heated front seats, an iPod jack and a six-CD changer. The Prestige rolls on 18-inch wheels and adds rear park distance control, keyless ignition and entry, a lane-change warning system and an upgraded 14-speaker Bang & Olufsen sound system.
The optional Sport package firms up handling (the S-line package for Prestige models is essentially an upscale Sport package). Other options include a navigation system with a back-up camera, adaptive cruise control, the Drive Select adjustable suspension system, rear-seat side airbags and a choice of wood trims.
The 2009 Audi A4 Cabriolet 2.0T comes standard with 17-inch wheels, an automatic soft top, power front seats, dual-zone automatic climate control and a 10-speaker audio system with a six-CD/MP3 changer. The 3.2 model adds 18-inch wheels and heated front seats. Major options include adaptive bi-xenon headlights, a navigation system, the last-generation MMI system and upgraded Bose speakers.
