Acceleration Problem

We have been using the 301 1.5 bluehdi 100 hp model in our company for about 3 years. Recently, we exchanged vehicles between ourselves. I had my old vehicle since zero km and I delivered the vehicle at 120.000. The vehicle that came to me was the same model, but a vehicle at 118,000. I could see the top speed of 190 km without any difficulty on the same road with the vehicle I gave. What draws my attention in the new vehicle is that the vehicle does not walk after 160 km. The vehicle has 8600 km to service.

It occurred to me that the driver before me might have deafened the engine. There is no accident or damage to either vehicle. What do you think might be causing the problem? Does the engine turn on over time with cyclic use?
