S-Tronic? FSI? Audi publishes glossary of efficiency technology terms

There have been a lot of new technologies introduced in recent years to help improve efficiency of vehicles. While we spend a lot of time here at ABG trying to explain how these technologies work, Audi is stepping up to try and help as well with a new glossary that explains technologies like direct injection, clean diesel, and brake energy regeneration. Audi, of course, uses its own branding for these technologies but the basic information applies generically to most applications. For example, FSI is Audi's name for gasoline direct injection, while S-Tronic is the automaker's branding for a dual clutch transmission. Regardless of what you call the stuff, there are some nice illustrations and the descriptions are generally pretty concise making this a handy reference guide. Download the guide as a PDF.
