The 2006 GMC Envoy XL is part of the model's second and final generation. This midsize SUV comes in two trims: SLE and SLT. Power is provided by a 4.2-liter inline-6 producing 291 hp or a 5.3-liter V8 with 300 hp. Both engines are paired to a 4-speed automatic transmission; rear-wheel drive is standard and four-wheel drive is optional. The Envoy XL boasts seating for seven, with a third-row seat. Key safety features include stability control and ABS brakes, though side curtains airbags are conspicuously absent. The comfortable, well-equipped cabin includes features like dual-zone climate control, CD player, keyless entry, and OnStar. Notably, the Envoy XL was discontinued after 2006.
