The GMT900 generation of the Silverado/Sierra arrived in the last quarter of 2006 as a 2007 model. It features a redesigned exterior, interior, frame, and suspension as well as power increases on certain engines. Like the previous generation GMT800's and earlier C/K lines, it takes many styling cues from the GMT900 SUVs of the same year. Like the GMT900 SUVs, these pickups have improved aerodynamics over their predecessors thanks to steeply raked windshields and tighter panel gaps which help improve fuel economy. The previous GMT800 models were continued through 2007 badged as "Classic," just as the GMT400 models continued for two years after the GMT800's introduction.
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.
Production continued until 2013.
The 2007 GMT900 generation Silverado and Sierra pickups represent a significant leap forward in Chevrolet and GMC’s full-size truck offerings. The redesign not only enhanced aesthetics by adopting styling cues from the GMT900 SUVs but also improved functional aspects such as aerodynamics and engine power. These trucks featured steeply raked windshields and tighter panel gaps, which reduced drag and consequently improved fuel efficiency, a key selling point at the time due to rising fuel costs. Beyond the visual and mechanical upgrades, the overhaul also brought advancements to the frame and suspension systems. These improvements contributed to better ride quality and handling, making the trucks more comfortable and capable for both work and daily driving needs. The refreshed interior design added to the overall user experience with updated materials and layout, meeting growing consumer expectations for comfort and technology. The continuation of previous GMT800 models as ‘Classic’ versions alongside the new GMT900 trucks provided consumers with options that balanced tradition and innovation. This strategy helped ease the market transition while embracing new technological improvements. The recognition these trucks received, including the 2007 North American Truck of the Year and Motor Trend’s Truck of the Year, highlighted their industry impact. These accolades reflect the trucks’ overall improvements in design, performance, and value. Production of the GMT900 Silverado and Sierra lasted until 2013, marking a successful lifecycle for this generation. It set a foundation for subsequent models, influencing design and performance benchmarks in Chevrolet and GMC’s truck lineups. Enthusiasts and industry experts often look back at the GMT900 trucks as a pivotal advancement in pickup truck development, blending rugged capability with enhanced efficiency and style.
