BTW, the system is available in 4 door Chevy pickups and Tahoes. It adds about $10K to the price.
You people continue to amaze me. You complain when GM puts out a system that gets 20 mpg, in the city, on a vehicle that weighs almost 3 tons. We all can't drive 50 mpg spam cans, or want to. Heck, a Tahoe would take the place of 3 vehicles in my yard: the minivan that holds 7 people, the Trooper I use to tow my boat and camper, and my wife's Explorer that barely ekes out 17 mpg.
