If we do indeed get the turbo 4, it's going to be a tough choice for a lot of people between that engine and the V8 if that car has close to 350 HP and gets decent gas mileage.
Plus the aftermarket possibilities for a turbo engine excites me a lot, especially with Ford's European tuner partner Mountune opening shop here in the U.S.
to make kits for the Focus and Fiesta STs. Maybe they will offer kits/intercooler upgrades for the 4 cyl Mustang. And no doubt other aftermarket options will pop up as well.
I think it's smart to add multiple engine options, similar to what Ford has done with the Fusion. Everybody can find their niche in terms of performance and price. We can probably expect a loaded GT to be in the low 40K range
, so I'm sure a lot of people might find a lighter and still solid performing turbo in the 30s to be an attractive option.
