Don't forget the obnoxious cricket fuel pump sound as well when sitting idle.
A TDI is going to continue to make noise while stopped at a light - some models of which can be very obnoxious (my friend's 05 TDI is stupid loud), where a hybrid will switch to electric mode and allow for cooler, quieter operation.

I think a lot of more modern cars (including the modern diesels) have engine-off systems for stoplights-- put it in neutral and let the clutch out and the engine clicks off. It re-cranks when you put the clutch in. EVs definitely help reduce smog, though-- especially if you don't live near the power plants.
