The 2004 GMC Envoy XUV is a unique and versatile vehicle that combines the utility of an SUV with the functionality of a pickup truck. It is powered by a 4.2-liter inline-six engine that puts out 275 horsepower or an optional 5.3-liter V8 that delivers 290 horsepower, both mated with a 4-speed automatic transmission. The Envoy XUV is available in two trims, SLE and SLT, with rear-wheel drive standard and optional four-wheel drive. The revolutionary 'MidGate' design allows the vehicle's rear half to transform from a fully enclosed SUV into an open-air pickup truck. It is equipped with OnStar telematics and a CD stereo system. However, it lacks the refinement and modern features of more recent models due to its age.
