Designed primarily for commercial purposes, the full-sized Express van can be purchased in cargo or passenger versions. Eight, twelve, or fifteen-passenger versions are available, as are heavy-duty versions. The tall cargo bay can carry large loads and the rear hinged doors swing open wide to facilitate loading. Stability control and curtain air bags are standard. V8 gas, natural gas (CNG), as well as diesel engines are offered and all mated to a six-speed automatic transmission. New for 2016 is OnStar 4G LTE connectivity, which includes a Wi-Fi hotspot.
