Spy Photos: 2010 Chevy Silverado HD
Competition aside, there's also the issue of federal regulations to comply with, so changes were necessary no matter what. Most noticeably, the bumper changes, gaining a strip of trim that extends across the top, doing away with the overemphasized corner look of the current cow catcher. Looking more closely at the bumper, the air intake in the middle appears to have grown in size. That opening feeds the transmission cooler, so the speculation is that the Allison transmission has picked up extra ratios. Of course, it could just be bigger to gain an edge on thermal management underhood, but we're going to jump on the bandwagon of being excited for more cogs spun by the heavily revised 6.6-liter Duramax diesel with urea injection. That'd be just the thing to tow the Alero.
