Nothing wrong with 4 cylinder turbos (it will make almost double the HP that my 1983 Mustang GT 5.0 made from the factory) but they have no business in a Mustang. The V-8 is part of it's personality. If you want a fast turbo motor, buy an STI.
If you ask me, doing the 4 banger with turbos was the right thing to do. You can fine tune it even further and squeeze more power out of it and do it for a cheaper price than just buying a V6 or a V8.
It looks so bland. Chevrolet definitely wins in the looks department. Now if only they could lighten the Camaro up a bit.
Chevrolet lightened up their 2014 Camaro Z/28 Nurburgring car in order to beat the 2014 Shelby GT500, but they took out stereos, A/C, power windows, ect... and still only beat the Mustang by 2 seconds. Its going to take a bit of craftiness to get the Camaro as light and as powerful as the Mustangs. Both have the potential to be stupidly fast cars but they'll need some work.
Koenigsegg also has that 5.0L V8 they use in their Agera that does 280 something on the runway, and its a production car. If only Ford could figure out how to do that with their 5.0's.
