General Vehicle Info
Vehicle classes are assigned based on maximum loaded weight. The Gross Vehicle Weight Rating (GVWR) is often used as an indicator. GVWR takes into account both the vehicle weight and carrying load.
Light Commercial Vehicles (LCVs) includes taxis, pickups, SUVs, vans, cutaways, strip chassis, and buses in Class 1 to Class 3.
Model Year (MY) changes
Manufacturers usually launch a MY in the summer of the calendar year, but they can launh as early as January 1st.
When a model goes through a major change (new generation), introduction of the new MY comes usually later in the year as the tooling needs to be updated requiring more time.
