That does not appear to be what Saab was saying.

Do you have anything to support an engine that gets nearly equal mileage on ethanol compared to gasoline?

[Mr. Lucky]

The Saab 9-5, on gasoline produces 260 hp with 258 lbs of torque. By just filling up with e85, and making no other adjustments, the engine will generate 310 hp and 325 lbs of torque. If you stomp on the throttle, the gasoline powered vehicle will go from 0 - 60 in 6.9 seconds, while the ethanol powered car makes it in a little under 6 seconds.

To compare apples to apples, you would need to back off the accelerator in the car on ethanol fuel so that its performance matched the 6.9 second time.

I never have learned how to post active links, but if you Google on "ethanol fuel challenge" you can find some interesting information on retuning flex-fuel engines to optimize mileage.
