Platform Heritage

The Audi A5 is a series of compact executive and grand touring coupé cars produced by the German automobile manufacturer Audi since June 2007. The A5 range also includes the coupe, cabriolet, and "Sportback"—a five-door liftback with a fastback roofline—derived from the Audi A4 saloon and estate models. Under Audi's internal platform numbering convention, the A5 is a member of the B-platform series of vehicles, sharing its platform designation with the A4 saloon and Avant. The first generation A5 (Type 8T) belongs to the B8 family, while the second-generation model (Type 8W6) is based on the B9. Both generations are derived from the Volkswagen MLB (Modular Longitudinal Matrix) architecture.
