Why is the performance of my BMW 4 Series slower than before?

I noticed that my BMW 4 Series is not accelerating as quickly as it used to. What could be the reason for this decrease in performance?

It is possible that your BMW 4 Series is due for a maintenance check. Make sure to bring it in to a certified BMW mechanic for a diagnostic test.

Have you checked your tire pressure recently? Low tire pressure can greatly affect your car's performance.

Another factor to consider is your fuel quality. Using low quality fuel can negatively impact your car's performance.
