I think GM has done there homework, it's the future.
There is no money in making V8's not to mention that's the way things are going that people will not be able to afford a V8, the future is all boring as bat **** and people will buy any rubbish nowadays, look at it this way the media push something and most people will just swallow it, look at gay marriage for example, they can change the definition of a word, bastardise it in fact and most fools will swallow it because of their blind ignorance, Climate change is another just swallowed by hype and spin, Global warming they called it first then had to back peddle from that because there is no factual proof at all.
It all comes down to how many boring dull people there are or what one can afford.
Look at the USA the garbage cars they made, big front wheel drive floating barge poll junk and people bough them. it's just transport to most people, not drivers cars at all.
RTS is dead, them days are over and we had people complaining about the VB Commodore back in the day, because so many were just hopeless drivers and then we went down the track of helping crappy drivers and it all started with all the ABS etc and most love it.
If you look back at the junk that Australians drove until the first XR V8 Falcon came out and then the HK V8 Holden that's when enjoying to drive a car started and many people were interested in such a thing, even most people would watch Bathurst even 70 year old mums, it was a big deal back then but now not many could give a hoot about it at all.
Times are changing, GM and Ford are not going to make drivers cars anymore.
