Between GMC and Chevrolet there was always a strong bound, as these two brands shared a lot of platforms and technologies. It’s the same case for the Sierra truck that even since its inception shared the same design and engines with the Silverado.
A new generation Sierra was launched at the same time with the first Silverado pickup in 1999 and both models were based on the old Chevrolet C/K pickup.
The new Sierra represented a huge step forward in terms of engines and technology, undergoing a lot of upgrades which helped it climb to the top of the pickups food chain.
The 1999 GMC Sierra was offered with a new family of V8 engines and also some upgraded old units. There were various configurations available including regular or extended cabs, short bed or long bed, three trim levels and rear- or four-wheel-drive versions.
