The ranking of the most quiet and the most noisy car

As is known,the noise in the car can have a big impact on the driver, causing fatigue and nervousness. The sound of the engine, suspension, tires and rolling wind – this is only part of the sources of acoustic discomfort. Automakers are struggling with them, improving noise and aerodynamics. Success is on their side: modern cars are much quieter for those who are sitting in the cabin. At least some of them.
