2008 GMC Envoy Full Review
Date Published: 4/30/08
2008 GMC Envoy Review
The 2008 GMC Envoy gains standard curtain side airbags and trims down its model lineup. This five-passenger midsize SUV is a traditional truck-type design that is shared with the Chevrolet TrailBlazer, Isuzu Ascender, and Saab 9-7X. SLE, SLT, and uplevel Envoy Denali trim levels return. Base versions use a 285-hp 4.2-liter inline 6-cylinder engine. Denalis have a 300-hp 5.3-liter V8 with GM's Active Fuel Management cylinder deactivation. Maximum towing capacity is 6600 lb. All Envoys have a 4-speed automatic transmission and are available with rear-wheel drive or 4-wheel drive that can be left engaged on dry pavement and includes a low-range gear for off-roading. Available safety features include ABS, traction control, antiskid system, and curtain side airbags. Options include power-adjustable pedals, DVD entertainment, and navigation system. Denalis stand apart with a chrome grille and other styling touches inside and out, plus load-leveling suspension and extra sound insulation.
Competition
Consumer Guide Automotive places each vehicle into one of 18 classes based on size, price, and market position. Larger than Compact SUVs, Midsize SUVs offer a mix of car- and truck-type construction, V6 and V8 power, and up to eight-passenger seating. This class also includes crossover vehicles.

Our Best Buy choices are the Honda Pilot, GMC Acadia, Mazda CX-9, and Saturn Outlook. Our Recommended picks are the Hyundai Santa Fe, Hyundai Veracruz, and Toyota Highlander.

New or significantly redesigned models include the Toyota Highlander.



News
Sources say Envoy and its cousins will be terminated at decade's end, possibly sooner. Factors include sluggish sales, uncertainty over future gas prices, and the market's general shift away from truck-type designs in the midsize SUV class. The new car-type Acadia effectively replaces Envoy in the GMC line.

Pros Cons

Towing ability Fuel economy
Consumer Guide® Road Test Ratings
Acceleration

4WD SLT 2WD Denali Class Average
6 7 5.5

Envoys and Ascenders with the 4.2-liter engine are unstressed in routine driving and do fine in highway merging and passing. Denali is strong from a stop and has fine passing power. The transmission is smooth and responsive.
Fuel Economy

4WD SLT 2WD Denali Class Average
4 3 3.6

In Consumer Guide testing, a 2WD Denali averaged 15.2 mpg. We've not had the opportunity to measure a 6-cylinder Envoy or Ascender. All use regular-grade gas.
Ride Quality

4WD SLT 2WD Denali Class Average
5 6 5.5

A load-leveling suspension is standard for Envoy Denali but not available on SLE, SLT, or Ascender. It is more composed than the standard setup, which allows float and wander at highway speeds.
Steering/Handling/Braking

4WD SLT 2WD Denali Class Average
3 4 4.4

Trucky, with a tippy feel in aggressive cornering and an annoyingly vague steering feel. Envoy and Ascender have a relatively tight turning radius that eases close-quarters maneuvering. Brakes have good stopping control but spongy pedal action.
Quietness

4WD SLT 2WD Denali Class Average
4 7 5.4

The 6-cylinder engine cruises quietly enough but sounds ragged at full throttle. The V8 is more refined. Some tire noise is audible at highway speeds, though that's drowned out by considerable wind noise, especially from around the sunroof--even when it's closed. Envoy Denali is markedly quieter in all conditions.
Controls

4WD SLT 2WD Denali Class Average
7 7 6.3

Envoy and Ascender share a user-friendly dashboard with smooth-acting switchgear. The available navigation system is relatively easy to use; it absorbs, but doesn't complicate, audio functions.
Details

4WD SLT 2WD Denali Class Average
5 5 5.4

Mainstream Envoys use unimpressive imitation-wood trim and are slightly more upscale than similar Chevrolet TrailBlazers for interior decor. Denali's leather and unique trim bits do little to improve the interior ambiance.
Room/Comfort/Driver Seating (front)

4WD SLT 2WD Denali Class Average
7 7 7.1

Good headroom and legroom, even for taller folks. The seats are fairly comfortable and supportive. The driver has a good view to the front and sides, but headrests and roof pillars hamper lane changes and backing up. Available power-adjustable pedals help tailor a comfortable position, especially for shorter drivers.
Room/Comfort (rear)

4WD SLT 2WD Denali Class Average
6 6 6.1

Six-footers have ample headroom and legroom, plus adequate under-seat foot space despite an uneven floorboard. The split bench seat is comfortable, fairly supportive, and wide enough for three adults with a little squeezing.
Cargo Room

4WD SLT 2WD Denali Class Average
9 9 8.6

The 60/40 split 2nd row seat with automatic-folding headrests converts easily to provide ample space.
Value within Class

4WD SLT 2WD Denali Class Average
6 4 5.8

We judge Envoy the best choice among GM-built midsize truck-type SUVs. It has a pleasing enough interior and a good ride and handling mix. Truck-tough engineering is a plus for towing. Still, crossover SUVs remain more sensible for most everyday users. Isuzu's Ascender shares the virtues of comparably outfitted Envoys, but we don't recommend them, as Isuzu is slated to stop selling light-duty vehicles in North America.

Pricing Key: Retail prices listed with each report are set by the vehicle's manufacturer. These figures appear on each car's federally mandated window sticker. Most price lists also include dealer-invoice prices. Dealer-invoice prices are what the dealer pays the manufacturer for the car and its factory-installed options. The destination charge is not included in the suggested-retail or dealer-invoice price and must be added to the cost of the vehicle. Car companies change prices frequently throughout the year. If the prices published do not match those on the vehicle's window sticker, the manufacturer has probably altered the price recently.
NA = price note available, NC = no charge.

Rollover Resistance 3
Side Impact, Driver 5
Side Impact, Rear Passenger 5
The National Highway Traffic Safety Administration (NHTSA) tests a vehicle's worthiness in front- and side-impact collisions and rates its resistance to rollovers. Front-impact crash-test numbers indicate the chance of serious injury: 5 = 10% or less; 4 = 10-20%; 3 = 20-35%; 2 = 35-45%; 1 = More than 45%. Side-impact crash-test numbers indicate: 5 = 5% or less; 4 = 6-10%; 3 = 11-20%; 2 = 21-25%; 1 = More than 26%. Rollover resistance numbers indicate the chance for rollover when the vehicle leaves the roadway: 5 = Less than 10%; 4 = 10-20%; 3 = 20-30%; 2 = 30-40%; 1 = More than 40%.
