17 MPG---- 70MPH steady driving
11-12MPG---city driving Highway would be better if the car had standard R&P gearing. It has much lower gearing(high numerically) and tops out about 145MPH at redline.

Oh yeah, if you spend a lot of time with the turbo spooled up, these cars drink like college kids with a beer bong on spring break.
