Which car is the quietest?

[Gideon]

Managed to measure the sound level inside & outside the car at this setting:-

E200 W213 since Oct 2018, air con switched on with fan at 5 speed. All measurements with Radio Shack Sound Level Meter with 'A' rating & with 'Slow' response. These parameters are necessary to measure the sound level impact to our hearings.

50 dBA = Private office setting

60 dBA = Normal conversation

70 dBA = Sound of vacuum cleaner

80 dBA = Curbside on busy street

1) Inside driver seat and all doors & windows closed with engine running: 52 dBA

2) Inside driver seat & with driver door open: 58.5 dBA

3) Car all doors & windows closed with air con on & standing infront of the front car boot: 63 dBA

4) Car all doors & windows closed with air con on with front car boot open & standing infront of the front car boot: 74.5 dBA

So far, W213 is probably the quietest car for E class. Would be interested to find out if others have better sound attenuation resulting in lower sound levels as shown above. Regards.

My previous W164 Sport Edition was 1 of the quietest MB I owned.

When the car was new and all doors closed, I find myself as if in a vacuum.

The ML was assembled and maybe still assembled in the US as Americans like SUVs.

This's the 1st MB that I can find sound deafening material in the door panels and maybe elsewhere in the car.

My current W213 is no where near to the quietness compare to my previous ML
