GM DEFENSE TO BUILD 10 HEAVY-DUTY SUBURBANS FOR THE U.S. GOVERNMENT

After GM Defense was awarded a $36.4 million development contract to build heavy-duty Suburbans for the United States government, our only question is will they run on diesel? While we don’t know the answer to that yet, we do know GM Defense plans to use its commercial vehicle architecture for full-size pickups and that the ‘Burbs will feature many off-the-shelf parts and components from the GM truck parts bin. In a press release from GM Defense, that means body, exterior, interior, brakes, and propulsion. But if GM does go diesel, which power plant will it be, the L5P 6.6L Duramax or the aluminum I-6 LM2 3.0L?
