This is a relatively low drag coefficient for a car, and it helps to make the A6 more fuel-efficient. The drag coefficient is a measure of how much air resistance a car experiences when it is moving. The lower the drag coefficient, the less air resistance the car experiences, and the more fuel-efficient it will be.
The 2014 Audi A6 has a number of features that help to reduce its drag coefficient, including:
* A sleek, aerodynamic design. The A6's body is shaped to minimize air resistance.
* A smooth underbody. The A6's underbody is covered with panels that help to smooth out the airflow beneath the car.
* Active grille shutters. The A6's grille shutters open and close automatically to control airflow into the engine compartment. This helps to reduce drag when the engine does not need as much air.
The combination of these features helps to make the 2014 Audi A6 a very fuel-efficient car. The A6 gets up to 24 MPG in the city and 31 MPG on the highway.
