How does the Audi A1 ensure efficient fuel consumption?

I'm interested in purchasing an Audi A1 but I want to make sure it is a fuel-efficient vehicle. Can you tell me about how the Audi A1 ensures efficient fuel consumption and if there are any specific features that contribute to this?

The Audi A1 is equipped with a start-stop system that automatically shuts off the engine while in idle, reducing fuel consumption and emissions. Make sure to also utilize the car's Eco mode for optimized driving.

The Audi A1's lightweight construction and aerodynamic design both contribute to its efficient fuel consumption. You can also monitor your fuel usage in real-time through the onboard efficiency display.
