Definitely looks better then the 2009 body style. It does look like Ford will be putting in new 5.0 V8 four-valve per cylinder setup, in the 2011 Mustang rumored to produce 400hp and 400lbs tq.

I will still take my 370z over a 400hp Mustang. Although it will be interesting to see how it will perform and if will retain the same curb weight. If doesn't gain much weight it will be fast, that’s +85hp and +80lbft increase over the 2010 V8 motor.
