It matters greatly I think. DI means more Power and/or efficiency...so there can tweaking for economy models and more power out of smaller displacement for performance models.Not knocking the question at all but -
Why does it matter?
Hi,I sense that they've only held off because of their unique engineering problem. A horizontally opposed engine stuffed between the frame rails in the front of the car means the cylinder heads must be very compact. So whatever fuel injection hardware they use needs to fit in less space without being so weird it breaks the bank.
If they can do it using the same components as a mass-market Nissan or Hyundai, the costs will be low. If they have to talk an injector manufacturer into making a whole new design that nobody else uses, then the price of DI goes way up.
DI should increase torque to the mid-high 70's lb-ft per liter...how much power and FE will the engine gain?
