What technology is used in the Audi A6 engine?

I want to know what kind of engine is used in the Audi A6 and what technology it incorporates.

The Audi A6 comes equipped with a turbocharged 2.0-liter four-cylinder engine, with options for a V6 or V8 engine depending on the trim level. This engine utilizes direct fuel injection and Audi's valve lift system technology for improved performance and efficiency.

The engine in the Audi A6 also features Audi's advanced start-stop technology, which shuts off the engine when the car is at a complete stop to save fuel and reduce emissions. The engine also has cylinder deactivation technology, which turns off cylinders when not needed to further improve efficiency.

For even greater performance and efficiency, opt for the Audi A6's available mild hybrid system. This system uses a 48-volt battery and integrated starter-generator to provide extra power and assist the engine during acceleration, as well as allowing for extended periods of coasting without engine power.
