The GMC Envoy got a few minor tweaks for 2007, including a tire-pressure monitor. This midsize luxury SUV also added a few new colors. Otherwise, it closely resembles its predecessors. The Envoy comes in 8 trims: 2WD and 4WD versions of the SLE1, SLE2, SLT1, and Denali. The SLE1, SLE2, and SLT1 trims come with a 4.2-liter, 291-hp inline-6 engine, while the Denali has a 5.3-liter, 302-hp V8. All 8 trims use a four-speed automatic transmission. The 4WD trims get 15 mpg in the city, 21 on the highway, while the 2WD trims get 16 and 22, respectively. The Envoy has 4 doors and seats 5. Cargo space comes out to 43.7/80.1 cubic feet. Overall, drivers agree that the Envoy provides comfort and powerful engines in its lineup. On the other hand, this midsize SUV could use better materials, better handling, and tighter steering. The Envoy needs to correct some noticeable flaws before it can assume a stronger position in the market.
