For Deep Blue to get 30-mpg on the highway,you'd need to drop the Cd to around 0.168.
You'd be looking at the GM Precept concept car,circa 1999.
That would require everything I did for the Spirit of Ecomodder,and no less than 8-feet of boat tail,unless you could get rid of your mirrors completely.
A new Colorado/Canyon Diesel will get the mpg,but your looking at around $40,000.00?,and expect to drive 62-mph.
