Noisy Acorns

[TimothyN]

Having driven solid German engineering for the last 20-odd years, I was really surprised today to hear the noise of being hit by (what I assume were multiple) acorns.

The first time it happened, I happened to be passing an artic in the opposite direction, and I thought he had taken my windscreen out with a stone, but there was no sign of damage, and it then happened a few more times as I drove along the beautiful lanes of Kent as they were pummelled by darling Amy.

Why are these impacts so, so loud in the cabin, compared to previous cars?

There is probably less sound insulation in the roof to save weight and because it's not needed, acorn bombs excepted.
