How does the Audi A7 achieve such impressive fuel efficiency?

I've seen that the Audi A7 has a very high fuel efficiency for a luxury sedan, even with its powerful engine. How does Audi manage to achieve this?

The Audi A7 achieves its impressive fuel efficiency through multiple design choices, such as its aerodynamic body, lightweight materials, and efficient engine management system. This combination allows for a more efficient use of fuel while still maintaining high performance levels.

One of the key factors in the Audi A7's fuel efficiency is its use of a mild-hybrid system, which helps to conserve energy and reduce fuel consumption. In addition, the engine features advanced fuel injection and combustion technology for optimal efficiency.

Audi has put a lot of effort into perfecting their engine technology, including their famous TDI diesel engines. These engines offer impressive torque and power while also being more fuel-efficient than traditional gasoline engines. This is a big reason why the Audi A7 can achieve such impressive fuel efficiency.
