Why does the 2021 Audi A6 have a fuel economy rating of 24 MPG city and higher?

I'm interested in purchasing a new Audi A6 and am impressed with the fuel efficiency. However, I'm curious as to what technology or design features contribute to its impressive rating. Can you explain why the Audi A6 has a fuel economy rating of 24 MPG city?

The 2021 Audi A6 features a turbocharged 2.0-liter four-cylinder engine, with a mild-hybrid system that helps increase fuel efficiency. This system recovers energy during braking and coasting to reduce fuel consumption and increase power.

Audi has also made improvements to the A6's transmission, using a dual-clutch seven-speed automatic instead of the traditional eight-speed automatic. This allows for quicker, smoother shifts and contributes to the car's improved fuel economy.

The Audi A6 also features start-stop technology, which automatically turns off the engine when the car is stopped and restarts it when the brake pedal is released. This feature reduces idling and improves overall fuel efficiency.
