There has been no confirmation that the 200 lbs weight loss is not a myth just like the New Edge size that had been rumored. With that being said there is far more to a C7 than just straight line speed. 713 rwhp was just made with a stock internal/ stock fuel system Procharged C7...on pump gas....
Before this thread goes off topic on who can make more power on stock internals and other crap, do you feel the 2015 Mustang will be on par with the C7 on a road course, acceleration, braking, etc???
