You put a TTV6 in a car like that for cost/simplicity purposes. The fewer engine families a car has, the simpler it is to build. The simpler a car is to build, the cheaper you can build it. This is the same reason that turbo 4 cylinders are replacing V6s in midsize cars.

So you're telling me a TTV6 off the powerband gets the same MPG as a V8?
Have you ever driven a turbo car before?
