My last car non renault was a 16 v petrol,no insulation.
This one 1.5 diesel does have some.(not allover)
I hadnt even thought about it until your post
Yup, I would agree with this. Pug 205 1.8d had insulation, 1996 Passat Petrol, 2007 Ka Petrol, 2000 Clio Petrol all without. It's to reduce noise transmission over your windscreen. This, I believe is where most of the noise will come from whilst moving. Maybe it also helps a diesel get to temp quicker, helps cold starting, prevent diesel freeze in winter?
