The 2003 GMC Envoy is a mid-size SUV that was produced by General Motors from 2002 to 2009. It shared its platform with the Chevrolet Trailblazer, Buick Rainier, and Isuzu Ascender. The Envoy was conceived as a slightly more luxurious and sophisticated option compared to the Chevrolet Trailblazer, with a focus on comfort, convenience, and refinement. It featured a distinctive front-end design with a large chrome grille, a sculpted hood, and sleek headlights. The interior boasted a well-appointed cabin with premium materials, comfortable seating, and available features like leather upholstery, dual-zone climate control, and a premium sound system.

The 2003 GMC Envoy was available with two engine options: a 4.2-liter inline-6 engine producing 275 horsepower and 275 lb-ft of torque, and a 5.3-liter V8 engine producing 290 horsepower and 325 lb-ft of torque. Both engines were paired with a 4-speed automatic transmission and could be equipped with either rear-wheel drive or four-wheel drive. The Envoy offered a spacious cabin with seating for five and a comfortable ride. It also delivered a decent towing capacity and off-road capabilities. The 2003 Envoy, like many of its generation, faced criticism for its modest fuel economy, underwhelming handling, and a tendency for mechanical issues. Despite these drawbacks, the Envoy remained a popular choice for families and individuals seeking a versatile and capable SUV.
