2005 Silverado/Sierra Refresh
More info is out about the truly new trucks on the all-new GMT-900 platform. First up on the new platform will be the SUVs (Tahoe, Yukon, etc.) for MY 2007. The all-new pickups come MY 2008. The GMC will probably look more like the edgy Teradyne concept and the Chevy will probably look more like the softer Cheyenne concept. These vehicles are still in design right now and the math data should be frozen in the next few months.
The new GMT 900s will be bleeding edge state of the art. They will have second generation quadrasteer, optional fully hybrid powertrains, DoD, almuminum Gen IV V8s, 6-speed automatics, a premium 500+ hp 48V DOHC V12 in the new Escalade and a new heavy duty 450 hp 7.0L V10 and HD 6-speed manual. Hopefully that's enough to chew on for now.
