Why do old car engines sound different?

Why do older cars sound louder?

It will likely be much more quiet than normal. This is because the bearings for the accessories wear over time. This is not necessarily a cause for concern, but if the noises become unusually loud, it should be diagnosed.

Why are modern cars quiet?

Aerodynamics: The shape of cars has changed, often in very subtle ways, in order to reduce drag and thus increase both a car’s fuel efficiency and performance. But an additional benefit of this has been a concomitant reduction in wind noise. That makes the cabin much quieter on modern cars than in the past.

How modern engines are different than the old engine?

Modern engines have a lot of technology that helps use less fuel while making more power than older engines, but they have one last thing that older engines just didn’t have: partners.

Why do new V8 engines sound different?

Why do bigger engines sound better?

The large pistons with the larger intake and exhaust valves sing a tune no other engine can match. BTW the larger valves and combustion chamber which is the engine heads and intake, exhaust system is bigger so engine has more air flow which also helps the sound of the V8.

How can I make my car engine quieter?

Why are Lexus cars so quiet?

Compared to non-luxury cars, Lexus vehicles come with thicker glass panels, insulating materials inserted at areas where noise can come in, and the engine is also usually insulated. Lexus is famous for tight panel gaps, which minimizes the amount of external noise that can come in.
