Why is the acceleration in my Audi A7 not as powerful as it used to be?

I've noticed that the acceleration in my Audi A7 has become sluggish and less powerful. It used to have a lot of kick when I stepped on the gas, but now it feels like it's struggling. What could be causing this issue?

It's possible that the spark plugs in your Audi A7 may be worn out and need to be replaced. This can affect the power and performance of the engine. Consider getting them checked and replaced if necessary.
