Understanding the Audi quattro® Engines

Audi pioneered permanent all wheel drive (AWD) systems in passenger vehicles thirty-five years ago with the quattro® engine, tailoring the engine to their specific models for optimal driving performance and traction. 

You probably purchased your Audi with the benefits of AWD in mind, however, we as drivers sometimes fail to think about how our vehicle is actually functioning until something goes wrong. 

With this in mind, we at JA Autowerks wanted to share some insights into the Audi quattro® engines. From their benefits to common issues, we’ve put together the highlight to arm you with the knowledge to be the best driver you can be behind the wheel or while shopping for a new Audi.
