The Silverado is an easy truck to live with, thanks to its comfortable ride and reasonable floor height. Access is fairly easy, as is cargo loading. The truck also offers generous towing and payload capacity. A six-speed automatic transmission aids acceleration and fuel economy, while selectable full-time four-wheel drive adds safety in slippery conditions. While side- and curtain-airbags are standard, IIHS side-crash test results are disappointing. A hybrid Silverado was offered as well. Test results also apply to the GMC Sierra.
