The Mustang doesn't really need IRS. Ol' Shel actually addressed this very subject a little while back, stating that the way the car is set up, an IRS design would have added a whole lot of cost without significant benefit.
That's a load. How come Hyundai can release this car with an IRS for the price of a Mustang, yet include more features and ammenities? It's simple, Ford has to pay it's way out of the hole they've dug over the years and the deletion of an IRS makes the only car they make money on anymore even more profitable. They didn't do it because it's just as good, they did it because it's adequate and cheap.
If I'm buying a soirts coupe, I don't want just adequate.
