The Chevrolet Silverado and its mechanically identical twin, the GMC Sierra is a series of full-size pickup trucks manufactured by General Motors and introduced in 1998 as the successor to the long-running Chevrolet C/K line. General Motors continues to offer a GMC-badged variant of the Chevrolet full-size pickup under the GMC Sierra name, first used in 1988 for its variant of the GMT400 platform trucks.
GMC created an upscale version of its Sierra 1500 in 2001 called the Sierra C3. For 2002, the name was changed to Sierra Denali.
GM launched a hybrid version of the Silverado/Sierra in 2004, becoming the first ever GM hybrid passenger vehicle. Starting in 2009, General Motors offers a second generation Chevrolet Silverado and GMC Sierra equipped with a Two-Mode Hybrid powertrain and 4-speed CVT.
