There is currently little to no market for diesels in the USA. I for one have no desire to drive all around Chicago looking for diesel pumps. Yes, Audi and Peugeot have wicked diesel racers, but again, they have massive budgets. The Z wouldn't get a race diesel engine...it would get a regular car diesel engine with some tweaking.

I didn't buy a Z for fuel economy. I don't care if it gets 30+mpg. If that's what I was looking for, I'd have a Prius. I want a fast, fun, lightweight car that performs well. If Nissan wants to improve fuel economy and performance together, make the Z 500lbs lighter. Lets get some CF panels, aluminum spaceframe, etc. That's far better than futuristic drivetrains.
