What are the most important features of the Audi A8 engine?

I'm considering buying an Audi A8 and I've heard that the engine is a major selling point. Can you give me a breakdown of the engine's key features and how they contribute to the overall performance of the vehicle?

The Audi A8 has a powerful V6 engine that delivers 335 horsepower and 369 lb-ft of torque. This allows for quick acceleration and a smooth ride.

One of the standout features of the Audi A8 engine is its mild hybrid system. This system helps improve efficiency by using an electric motor to assist the engine during acceleration.

The engine also has a cylinder deactivation feature, which shuts off half of the cylinders when they are not needed. This helps conserve fuel and reduce emissions.
