What's New for 2006

Changes to the 2006 GMC Envoy include new 18-inch alloy wheels for the Denali trim and the addition of stability control, OnStar and cruise control to the standard equipment list of all Envoys.


The Envoy nameplate dates back to 1998 when GMC introduced a gussied-up version of its standard Jimmy SUV to appeal to buyers looking for an upscale ride. Even with a strong V6 and options aplenty, however, the first GMC Envoy was totally outclassed by its competition. The Jimmy name was dropped in 2002, and the Envoy became GMC's only midsize SUV. That was also the year the Envoy received an extensive redesign. It now comes to the table with specifications and features that allow it to compete more favorably against its arch rival, the Explorer (also fully redesigned in 2002). A longer and wider body gives the Envoy a substantial look, while providing considerably more room for passengers and cargo inside.

The 2006 GMC Envoy represents a vast improvement over its predecessor, but ultimately, it doesn't measure up to competitors such as the Explorer or 4Runner. While its handsome exterior and roomy interior may attract consumers, GMC needs to come up with a better compromise between cushy ride quality and confident handling; specifically, it should lose some of the former to gain some of the latter. The company also needs to take a look at the materials used inside the cabin -- too many of them are of dubious quality for a vehicle in this price range. The midsize SUV class is populated with extremely capable vehicles, and unfortunately, the Envoy has yet to prove that it's got what it takes to overtake the segment leaders.

Body Styles, Trim Levels, and Options

The four-door GMC Envoy seats five and comes in three trim levels: SLE, SLT and Denali. SLE versions come with a cloth interior; dual-zone manual air conditioning; a CD player; power windows, mirrors and locks; keyless entry; and 17-inch wheels. SLT models are loaded with just about every feature available including a driver information center, automatic climate control, leather seating and a leather-wrapped steering wheel with radio and climate controls, just to name a few. The Denali adds unique trim inside and out, as well as 18-inch alloy wheels, power-adjustable pedals, heated seats and a Bose audio system. The Envoy also offers a rear-seat DVD entertainment system, a DVD-based navigation system, upgraded audio systems and satellite radio as options.

Powertrains and Performance

SLE and SLT Envoys are powered by a 4.2-liter, inline six-cylinder engine. Rated at 291 horsepower and 277 pound-feet of torque, this engine outpowers most of its competitors' V8s, let alone their V6 offerings. It's connected to a well-designed four-speed automatic transmission that delivers firm, precise shifts. Both two-wheel-drive and four-wheel-drive models are available. Properly equipped, the six-cylinder Envoy can tow 6,300 pounds. The Denali ups the ante with a 5.3-liter V8 that pumps out 300 hp and 330 lb-ft of torque, and it can tow up to 6,600 pounds.


Four-wheel antilock disc brakes and stability control are standard on all Envoys, while full-length head curtain airbags are optional. There are three-point seatbelts at all five seating locations. When equipped with the optional airbags, the GMC Envoy earned five stars (the best possible) for its protection of front and rear passengers in NHTSA's side-impact test. Frontal-impact tests resulted in a three-star rating for driver and four stars for front-passenger protection. The IIHS rated the vehicle "Marginal" (second lowest) after conducting its frontal offset crash test.

Interior Design and Special Features

Inside, the Envoy's cabin offers plenty of room for five adult passengers. Brushed nickel accents grace the console and instrument panel, and wood accents add a touch of class to the uplevel Denali trim. Materials quality has improved over the years, but unfortunately, cheap plastic still dominates the dashboard and door panels. The 60/40-split rear seats fold for cargo-loading flexibility; with the seats folded, the GMC Envoy has a maximum cargo-carrying capacity of 80 cubic feet.

Driving Impressions

Out on the road, the 2006 GMC Envoy delivers a well-cushioned ride that most shoppers will like. Unfortunately, the steering offers little in the way of road feel, and handling is sloppy around corners. Off-road, the Envoy is capable of tackling the typical obstacles one encounters while trying to access trailheads and campsites. Ultimately, the most enjoyable aspect of this utility vehicle is its brawny engine choices.

Vehicle: 2006 GMC Envoy Denali 4dr SUV 4WD (5.3L 8cyl 4A)

I own a 2006 GMC Envoy Denali. I bought it 2 years ago with 65,000 miles on it. I had it less than a year and the oil started disappering. Took it into the shop $600.00 later it was fixed, supposedly. Shop guy told me that if it happened again I would no doubt need a new engine :( Guess what it happened today, oil pressure dropped to zero and the check engine light is on and I was only down 1/2 qrt of oil. This vehicle has nickeled and dimed me to death and isn't worth crap for trade. Very disappointed in the GMC. Also GMC will not stand behind there product.

Vehicle: 2006 GMC Envoy Denali 4dr SUV 4WD (5.3L 8cyl 4A)

This car looked so amazing, and being young my husband and I thought we needed a beautiful car like this. It w as 6 months old when we bought it. Fuel card gone out twice. The air bags that lift the car got a leak and had to replace with normal shocks. (Expensive!) Air conditioning went out driver side. Front suspension needed replaced, would not turn. Not all our issues list :( NOW: All of a sudden when driving home from work, at night, my headlights completely turned off! I thought it was just a one time thing but happened a week later with my kids in the car on the highway! Oh my goodness...I am so upset, haven't driven it at night or hardly at all.

Vehicle: 2006 GMC Envoy SLE 4dr SUV 4WD (4.2L 6cyl 4A)

I purchased my 2006 Envoy used from Carmax when it had 32,000 miles on it. At the time we bought it, it was making a whining noise from the motor, which the salesman assured us was normal. It was not normal. Left me broke down on the side of the road when the idler pulley broke and tore up the sepenteine belt. Fuel gauge no longer works and check engine light stays on. More recently my driver's side door squeks badly and one of the shocks on my back hatch blew out. I wanted to get a brand new Acadia but not sure I want to purchase another GMC. They do not even have any recalls for any of the problems. Do not buy..

Great car for the first

Vehicle: 2006 GMC Envoy Denali 4dr SUV (5.3L 8cyl 4A)

This was a great car for the first few years. I bought it new a month or two before the 2007's came out and got it for right around invoice price. The interior is nice, performs well, tows well (but I've never towed anything super heavy). However I started having problems shortly after the warranty ran out. -At 40K the fuel level sensor went out, the dealer wanted $700 to fix. I had it done with a $35 part from ebay and $200 labor. -At 72K the transmission went out, $2300 -At 92K the engine had to be replaced, $6700 -At 93K the throttle sensor had to be replaced Even though it was great at first, the last 1-2 years have made me regret buying this car.

Vehicle: 2006 GMC Envoy SLT 4dr SUV 4WD (4.2L 6cyl 4A)

I can't understand all the complaints about the Envoy. Must be other brand dealers trying to kill sales. I have had this one over 2 years and presently have 113,000 miles on it with no issues at all. Bought it used with 46000 on it and will buy another if I can find one. The only mistake GM made was going from this to the Arcadia. Mine has the 4.2 4wd, will go anywhere and pull anything I want to.

Reliable vehicle

Vehicle: 2006 GMC Envoy Denali 4dr SUV (5.3L 8cyl 4A)

I really love this SUV. It has been very reliable so far and have not had any problems. Of course, it is the DENALI, everything is top of the line. The leather seats are comfortable, the vehicle rides smoothly and haven't had any problems these four years. I would also like to point out that the regular mpg in the city is 16.5 / 17 but on the highway I noticed that on our last trip it did 22 mpg, which I think that for the size and weight of this vehicle was pretty good. I definitely would recommended.
