Like all North American manufacturers’ pickups, the GMC Sierra is offered in several configurations. Four engines, two transmissions, two powertrains (rear-wheel drive and 4x4), three box lengths and three cab styles. There’s even a hybrid model! Not to mention the numerous options. By the way, the hybrid is no gimmick – the dual-mode helps save several litres of gas. If you want more luxury, consider the Denali versions.
