Loud sound engine

According to me, my car 2013 peak motor sound is too high for me, according to other cars I wonder what is the difference between all of these vehicles, the sound of the motor is a bit high, hdi alure bide hdi alure and blu hdi alure

if allure is only package blue hdi, the engine type is euro 6 engine, our vehicles are a little weak as insulation 508 3008 5008 there is not much difference

when my friends pressed the gas to the top, the change of the motor sound to the duration of the job is euru5 engine formation, so euro 5 engine gives the sound in the injector when the gas is pressed fine

One of the most silent diesel engines, hdi engines, hodja. but the euro 6 engines you call are quieter. thanks in advance for the information
