GM continues to make steady progress readying updates for its heavy-duty pickups, including a minor face-lift. Originally thought to be badged as 2010 models, new information now pegs the revisions for the 2011 model year.
The one-ton Chevrolet Silverado 3500 in this picture sports the same grille as the current half-ton Silverado 1500, but as we first reported last year, we think it's temporary. A different grille with better fitment is likely in the works. The front bumper, however, is believed to be ready for production. GM has softened the huge metal flares at the corners of the current Silverado HD's bumper by topping off the uppermost portion with plastic from end to end. The inlet in the middle of the front bumper feeds air to the truck's transmission oil cooler. It's about a third larger than the current inlet, which makes us wonder about the changes GM has in mind for the V-8 Duramax diesel's Allison transmission.
The Duramax is expected to receive a significant increase in horsepower and torque next year (well over 700 pounds-feet of torque, sources tell us) as well as meet the toughest clean-diesel emissions standards in the world.
