Yes, you're absolutely right. I didn't buy the car for gas mileage. I'm going to put the fuse back in before I drive it again. I read that the spoiler generates 356 Newtons (80 pounds) of down force to the rear of Crossfire at 130 km/h (near 80 mph). I have a theory if the Xfire get lighter the faster you go then all of that lift could hurt gas mileage and by deploying the spoiler may actually improve mileage.

Another thing is I tend to drive this car faster than I do any of the other cars I own. If I don't put the Xfire in cruise control I will gradually keep speeding up. I've hit 90mph before I realized it. I have not had a ticket since 1977 but if I ever get another one it'll probably be in my Crossfire!
