Envoy loses its standard front side airbags for 2003, but is available for the first time with a V8 engine. GMC's midsize SUV comes as a 5-passenger regular-length model and the longer, 7-passenger Envoy XL. Beneath their GMC-specific styling details is a basic design and powertrains shared with Chevrolet's TrailBlazer and longer TrailBlazer EXT. Oldsmobile's Bravada also uses this body-on-frame platform, but comes only in 5-passenger form. XLs have a 16-inch longer wheelbase than regular Envoys, an elevated rear roofline, and 3-row seating. Standard on all is a 275-hp inline 6-cyl engine. An XL-only option is a 290-hp V8 borrowed from GMC's full-size SUVs. A 4-speed automatic is the sole transmission. All Envoys offer rear-wheel drive with available traction control or GM's Autotrac 4WD that can be left engaged on dry pavement and includes low-range gearing. Antilock 4-wheel disc brakes and 17-inch alloy wheels are standard. Front side airbags are now a $350 option; the driver's bag covers head and torso. Curtain side airbags are unavailable. A rear-seat DVD video system is optional. Aimed upscale of TrailBlazer, Envoy costs slightly more and offers some options the Chevys don't, including rear load-leveling air suspension. The fuel tank on regular-length Envoys increased at midyear to 22 gal from 18.7. Envoy's performance and accommodations are similar to those of corresponding TrailBlazers.
