    Exclamation 2011 Duramax - Phone Conversation with head of GM Diesel Technology

    Just got off the phone with Gary Arvan, the Chief Engineer for Duramax. GREAT phone call, lots coming down the pipe for the 2011 Duramax and I've got the scoop on the new Urea injection system designed to cut down on NOx emissions. We also talked about the future of Diesel technology at GM and what you can expect from them in the future.

    I should have a write-up done by later this week.

    10 Chevy Traverse LT AWD
    02 Chevy Trailblazer LS (110K+ miles - loaded except for 4WD - WRECKED!)
    99 Chevy Cavalier LS (105K+ miles - commuter car)
    78 Chevy Suburban Silverado (454, 3/4 ton)
    62 GMC 3/4 ton Pickup (350 police interceptor)
