What is the Valvelift System in Audi A5 Engine?

Can anyone explain the functioning and benefits of the Valvelift System present in Audi A5 engine? How is it different from models without this feature?

The Valvelift System is a variable valve timing technology used in Audi A5 engine, which provides improved power, efficiency, and emissions. It continuously adjusts the lift of the intake valves according to engine speed and load, resulting in optimized combustion and performance.

As for the benefits, the Valvelift System allows for a better balance between power and efficiency, providing more torque at lower RPMs without sacrificing fuel economy. It also helps reduce emissions and improves overall engine response and smoothness.

For models without this feature, the timing of the intake valves is fixed, causing a compromise between low-end torque and top-end power. The Valvelift System eliminates this compromise by automatically adjusting the valve timing for improved performance in all driving conditions.
