"What's New for 2003: For 2003, Envoy buyers are able to order certain options individually, rather than as part of an equipment package, adding potential savings and increased flexibility. The sport-ute's already powerful Vortec 4.2-liter inline six also gets a slight bump in horsepower, up from 270 to 275, and Envoys now boast a new four-position headlamp switch that permits drivers to turn off the vehicle's daytime running lamps and automatic headlamps when necessary. Additionally, the Envoy gets a larger fuel tank that holds 22 gallons. Previously standard side airbags are now optional, while autodimming side mirrors and the rear seat overhead compartment have been deleted."
