I've been concerned about the lack of noise also... but it does appear that it can be created artificially which will be better than nothing.

M-Sport told me that they can sort out sound. It could be a WRC turbo noise, or even V10 or V8 apparently. (Also the cars may be significantly cheaper to run).

But I think that hybrid will be next with a small petrol motor for real noise...
