Audi AG – Test Vehicles & Prototype Fleet (Erlkönig / Erprobungsfahrzeuge)

Ingolstadt, Germany

Audi’s test vehicle fleet includes prototype “Erlkönig” cars, durability testers, and pre-production vehicles used for development, validation, and homologation. These cars support software tuning, safety testing, emissions compliance, and market-specific approval (e.g. US specs). They are heavily instrumented engineering vehicles used before models enter mass production.
