So IRS, 2.3 liter EcoBoost with twin scroll turbo available with 305+ HP. V-6 carries over and 5.0 V-8 gets a power upgrade. I for one will miss the solid rear axle. IRS will just make the car more sophisticated and Muscle Cars are more about brawn than finesse. Some people will say that the IRS handles better but historically solid axles have done just fine on the track running right with IRS mustangs because race tracks are usually pretty smooth and no one cares if their race car rides a little rough. The durability and straight line performance will be missed. I'm excited about the 2.3 and maybe a Nano V-6 down the road, I know V-8 rumble is cool but with good torquey EcoBoost options, I'll miss the rumble far less than the solid axle. As for looks, I like the front but the back seems kind of blah. The car was widened and shortened (in height) and it somehow makes the tail look too long. I miss the side scoops or at least a beauty line on the side. I hear the car is lighter which is always nice and the fact that it got IRS and lost weight should make it a more dynamic car. If Ford builds the Nano V-6 right and it can rival a Nissan GTR power when tuned, the new mustang might become the poor man's Godzilla. That would be cool because there is no american car that really fills that role. I think there is more good than bad, what do you think?
