What can you tell us about the performance and turbo lag of the GXP and the Turbo engine? What kind of fuel economy can we expect?
The turbo lag is minimal to mostly not detectable. The boost builds very quickly, and is one of the best turbo engines I have ever personally driven. The torque comes up to peak quickly and pulls very consistently to about 5300 or 5500 rpm and then drops off. If you are running above 2200 rpm and push the pedal, the response is nearly immediate and max boost is reached in about a half second or so. I find it very fun and very impressive, and I think those of you ordering the GXP are in for a wonderful surprise.

On the way here to Kansas City, I averaged about 28 miles per gallon, and the Driver Information Center showed peaks of 32 MPG. I was getting about 350 miles per tank on the way here, filling with about 12.5 gallons.
