Not going to happen. Performance = fuel mileage. A Honda S2000, with its little I4, gets the same mileage as a Chevy Camaro V8. It also performs roughly the same. The only way to make power is to burn fuel. More power means more fuel burned. With a 250 horsepower car, you're looking at 18-19 mpg city and 25-27 mpg highway. Likely on premium fuel. (Yes, there will be some variance around those numbers, but not more than a couple mpg.)
250 horsepower is quite healthy and the reality of that is that it will take a corresponding amount of fuel.

Gonna have to disagree a bit on this one. I agree that making more power requires consuming more fuel, but 9 times out of 10 in the real world, you're NOT making more power, even in the engine with higher power potential.
The V6 in my Accord makes "only" 240 HP, but I get 28-30 MPG in real-world mixed driving on the recommended regular fuel. That's more than the perfect-world EPA rating of the S2000, which makes more or less the same peak power, weighs 500 pounds less, has an extra gear ratio, and has a manual instead of a slushbox. There are a lot of factors that go into gas mileage, and peak power only matters when you choose to actually utilize that power. Yeah, my mileage drops when I carve canyons and glue the throttle to the floor, but in day-to-day driving, I rarely need to use more than 1/3 throttle, and my mileage is better than my old 125 HP Accord.
Granted you're not going to find 250 HP and Prius-level fuel economy together in one car, but some V6's come REALLY close to matching the fuel economy of the wimpier 4-cylinder versions of the same cars.
