Here's a quote from another forum site I visit........
Anyone here ever heard anything, or know anything about this? I'm curious as to what technology is being incorporated into this truck.A guy that works for my brother was going to montana a few weeks ago and bought a brand new 4 door 4x4 chevy truck. He was curious what kind of gas mileage he was going to get out there but he thought driving his brand new truck would be worth it. Him and his buddies left grand rapids, MI and drove to Minnesota. He thought his gas gauge was broke because it hardly moved so he filled up and it only took $9. He got to montana and never had to fill up again and still had gas. He was freaking out and thought something was wrong but kept going. After their week long trip they headed for home. They left Montana and never filled up until michigan. HE AVERAGED 87 MILES PER GALLON. He was blown away and nobody beleived him except his buddies that was with him. He called his dealer and said I hate to bitch but my truck is getting 85 miles a gallon and dealer told him good for you. 2 weeks later GM tracked him down and said they needed that truck back somehow it got mixed up with regular trucks and that was their 1 and only test truck. The guy said no way this thing gets 85 miles per gallon and GM told him that the price tag on that truck right now is $400,000 and wait until it broke and it would cost $90,000 to fix it. GM let him pick out any truck he wanted and gave his wife $10,000 towards a vehicle if she bought that day. So he gave it back and they said they are trying to get the cost down under $100,000 before they produce them. A long story short the manufacturers are working on trucks that get good fuel economy, although they may cost a bit at first.
