I love turbo cars and I´ve had several turbo Volvos, my current Volvo is a V60 with a 2.0 4cyl turbo with 240 hp (it has the Ford ecoboost engine)... but for me a Mustang has to have a V8. My Volvo is quite a fast car but the 5.0 makes it feel like a snail. Nothing substitutes the V8 rumble as part of the Mustang owning experience.
And being totally honest.. the "Eco-boost" engine has nothing "eco" about it. My guess is that in real world driving conditions the eco-boost Mustang is going to have worse mpgs than the 3.7 V6.
