Ammo, I agree regarding the Shelby, we had a 2011 for a short time that I really was impressed with. I think personally that they are going to do a Shelby or high performance model, in the 6 to 700 bhp range. Why wouldn't they, they have sold pretty well, and it looks bad on them not having a competitor for the Z28, ZL1, etc from the Camaro line.
I do like the new body style of the 2015/16 Mustang, and I also really like the whole turbo 4 motor idea for the entry level models. Even this engine will have far more HP/torque than the original 5.0l engine in the late 80's and early 90's models, pre 1993 and the subsequent modular 4.6's. It'll be a neat car for the tuners, it should be fairly cheap for the base model with the turbo 4, and just wait until the mods start coming out for that one. I predict it'll be the new "it" car for modders. The 2.3 Ecoboost going into the entry level models will have a twin scroll turbo, so torque and HP should be on tap a lot lower in the RPM range, and is rumored to put out 300hp/300torque, which is amazing from such a small 4 cylinder motor for an American car - that is in the range of the best "Euro" high performance engines in the 2 liter range. It also is going to get 35 mpg so they are saying, left stock. Now THAT is quite a car for the price it's going to come in at. Now imagine a little work done to that motor, it won't take much in terms of mods, programming, and perhaps higher boosting turbos to put that thing into the 4 or 450HP range, or in fact much higher. Exciting times for drivers looking for a car to mod, a great alternative to buy American and have a very, very improvable car.
