About the 2009 Audi A4

B8 generation, first year for the US sedan and Avant; prior-generation B7-based Cabriolet, final year

Audi positioned the A4 as its compact luxury model that blends everyday comfort, clean interior design and responsive road manners. Its strongest differentiator was broad quattro AWD availability, joined by three distinct body styles: a practical sedan, cargo-friendly Avant and four-seat Cabriolet. Audi’s marketing emphasized direct-injection engines, carefully finished cabins and balanced performance rather than outright sports-car behavior, making the A4 a versatile alternative to other German compact luxury cars.

The redesigned sedan serves as the everyday core of the range, while the Avant combines a roomy cargo area, standard quattro AWD and a panoramic glass roof. Turbo four-cylinder models balance everyday performance and fuel use, while the 3.2 Quattro pairs a V6 and AWD with heated leather seats. The Cabriolet keeps its power-operated soft top and offers either front-wheel drive or quattro AWD, depending on trim.

What changed, by category

Structural

The sedan and Avant move to the new B8 platform. A longer wheelbase and wider track create more cabin space, while moving the front axle forward improves weight distribution.

Powertrain

The sedan and Avant receive updated direct-injection engines, led by a 211-hp turbocharged 2.0-liter four-cylinder and a 265-hp 3.2-liter V6. The Cabriolet retains its prior-generation engine specifications.

Styling

The sedan and Avant receive completely new exterior designs. The carryover Cabriolet gains sport-styled bumpers and grille treatment as standard equipment.

Tech

The sedan and Avant get redesigned infotainment and cabin controls. Bluetooth hands-free calling becomes standard on the Cabriolet.
