The Mustang won't be using the old Explorer engine anymore. Starting next year.
It is supposed to be getting a version of the 3.7 Liter already in used in other Ford models.
It will make over 275hp. Much closer to the Camaro's 300hp V6.
This should be a really nice car. There is really no need for V8s anymore in our new "2009 over $3 a gallon world".
(Which is what I just paid yesterday, by the way...)
