Chevrolet » Silverado 3500HD '07
The redesigned GMT900 generation of the Silverado arrived in the last quarter of 2006 as a 2007 model. It features a redesigned exterior, interior, frame, and suspension as well as a power increases on certain engines. It takes styling cues from the 2007 GMT900 SUVs and the Chevrolet Colorado pickups. Like the GMT900 SUVs, these pickups also have greatly improved aerodynamics over their predecessors GMT800 like steeply raked windshields and tighter panel gaps which improve fuel economy. The new Silverado earned the North American Truck of the Year award for 2007 and was Motor Trend magazine's Truck of the Year for 2007. The Generation III small block V8 engines offered in the GMT 800 trucks will be replaced in the GMT 900 series by the Generation IV small block V8 engine family, featuring upgrades such as increased power and Active Fuel Management on the 5.3 L and 6.0 L V8s. The 8.1 L big-block V8 is no longer offered on the Heavy Duty models, and no replacement has been announced. The majority of the GMT 900 trucks continue to be equipped with the four speed transmission that was found on the GMT 800 platform.
