What is cylinder on demand technology in the 2021 Audi A6?

I heard that the 2021 Audi A6 has a cylinder on demand technology. Can you explain what it does and how it improves performance and efficiency?

Cylinder on demand technology is a feature in the 2021 Audi A6 where the engine automatically deactivates certain cylinders during low power demand, resulting in improved fuel efficiency and reduced emissions.

It's essentially a cylinder deactivation system that switches between using all 6 cylinders or just 4 when not as much power is needed. This helps conserve fuel and reduce CO2 emissions.

Cylinder on demand technology is a form of engine management that improves fuel economy by using only half the cylinders during lighter driving loads. This not only saves gas, but also reduces wear and tear on the engine.
