A friend of mine in town has had his SHO since December and is getting great gas mileage, mostly in town driving he is averaging about 20mpg. He has a very heavy foot too, pretty impressive. I did not order my SHO because of the MPG it gets but it will be a welcome improvement over my 08 Pontiac G8 GT that is getting 13mpg in town and 22mpg on the highway! Looks like the direct injected/turbo motor is a great performer plus it does not gulp the gas.......
