What technology does the Audi A4 utilize to improve fuel efficiency and reduce emissions?

I am interested in learning more about the inner workings of the Audi A4 and how it promotes eco-friendliness. Does it use any specific technology or design features to reduce its carbon footprint?

The Audi A4 utilizes a technology called 'Cylinder on Demand', which shuts down selected engine cylinders during low demand situations to reduce fuel consumption and emissions. My personal advice would be to keep an eye on your engine temperature and regularly check your engine oil levels to make sure everything is functioning properly.

The Audi A4 also has an aerodynamic design with features such as a rear diffuser that reduces drag and improves fuel efficiency. Additionally, it utilizes an efficient start-stop system that turns off the engine when the car is idling. My advice would be to regularly service your car and keep your tires properly inflated to optimize fuel efficiency.
