How can the Audi A6 improve fuel efficiency?

I am considering purchasing an Audi A6 but want to prioritize fuel efficiency. What options or features should I look for in my search?

One way to improve the fuel efficiency of your Audi A6 is to choose the hybrid model, which combines a gasoline engine with an electric motor for better mileage. Additionally, you can opt for the energy recuperation system, which converts energy that is usually lost during braking and deceleration into usable electric energy.

Another way to improve fuel efficiency is by using the Audi drive select system to adjust your driving mode to 'efficient.' This optimizes your engine, transmission, and other systems for maximum fuel economy.

Investing in aerodynamic features, such as low rolling resistance tires and a front grille air shutter, can also greatly improve the fuel efficiency of the Audi A6.
