The "V" designation in GMC V1500 models defines four-wheel drive capability because it separates these models from "R" models equipped with dual-wheel systems only. Each V1500 division included both Sierra pickup trucks and Jimmy SUVs. During its production date range the GMC V1500 utilized 5.7-liter V8 and 6.2-liter diesel V8 motor sizes paired with a 4-speed 700R4 automatic transmission system.
