The R8 quattro model is particularly well specced, but you can still add the R8 Performance Design package for $5,200. This gives you a mix of leather and Alcantara on the racing shell seats, an Alcantara-clad steering wheel with Mercato Blue stitching to match its new floor mats and shift lever. You also get blue brake calipers for the complete theme. This model has further access to a carbon fiber front sway bar at $1,100, while the 13-speaker B&O audio upgrade costs $1,900. If you don't want AWD but do like carbon fiber, the RWD model can be equipped with the Carbon Interior package for $3,400, adding additional carbon inlays to the cabin. The Premium package is more expensive at $5,900 thanks to its B&O sound system, extended leather sub-package, illuminated door sill inlays, and Alcantara headliner. Added from 2022 onwards is the $12,900 Dynamic package that adds carbon-ceramic brakes, a different style of 20-inch wheel, and racing shell seats. The other new package is the $3,600 Sport Exhaust package (standard on the GT) that adds a Sport exhaust with black tips, a Sport steering wheel, and a Performance mode to the Audi Drive Select system. How much more you want to add is up to you and your bank balance.
