2006 GMC Envoy Test Drive

Baby Steps

The GMC Envoy gets few changes for 2006. It's as capable as ever, but no more exciting.

Introduced for the 2002 model year to replace the former and long running GMC Jimmy, the Envoy shares platforms and power trains with a slew of other midsize General Motors trucks, including the Buick Rainier, Chevrolet Trailblazer, Isuzu Ascender and Saab 9-7x.

The Envoy comes in standard- and long-wheelbase XL versions, with SLE and SLT trim levels. Opulently equipped Denali models in both lengths were added in 2005 and are the focus of our coverage. The Envoy XUT version that features a unique sliding rear roof has been discontinued for 2006.

After the Trailblazer, the Envoy is the second best-selling midsize SUV at GM. Be aware that Consumer Reports has consistently rated the current-generation Envoy's reliability as "much worse than average."

The longer XL model includes third-row seating and is capable of seating a total of seven passenger. The XL's wheelbase and overall length actually exceed that of its full-size stable mate, the GMC Yukon.

Changes for 2006 are minor. The exterior has been freshened and all Envoys now come with StabiliTrack electronic stability control standard. The Vortec 5300 V8 engine gets "displacement on demand" standard. This feature shuts down half of the cylinders according to engine load in order to optimize fuel by up to eight percent.

The brakes have also been tweaked on 2006 Envoys, and there are two new shades of red exterior paint. The top-of-the-line Denali models get different 18-inch aluminum wheels.

There is a choice of rear-wheel drive or Autotrac four-wheel drive. The base engine is a 4.2-liter inline six-cylinder engine that generates 275 horsepower. It's more powerful than some competitors' V8 engines and gets respectable fuel mileage for a truck (16 miles per gallon in the city and 22 mpg on the highway).

The 5.3-liter V8 produces only 15 hp more than the six-cylinder, but cranks out a generous 325 pound-feet of torque for quick acceleration off the line and better towing ability (up to 7,200 pounds). The only available transmission is a four-speed automatic.

While the Envoy is not sporty, it does offer a smooth ride. Its Luxury Ride suspension features stabilizer bars and high-pressure gas-filled Bilstein shock absorbers to soak up bumps.

Standard equipment includes dual-zone air conditioning, a stereo CD player, keyless entry and a leather-wrapped tilting steering wheel. Higher trim SLT versions add automatic climate control, rear audio controls, leather upholstery and power heated fold-away side mirrors with integrated turn signal indicators. Major options include the OnStar communication safety system, adjustable brake/accelerator pedals, a navigation system and rear-seat DVD entertainment system.

The top-of-the-line Denali models are loaded with amenities. They're distinguished by unique styling cues — chrome trimmed, billet-look grilles, monochromatic exterior trim and different front and rear fascias. Additional acoustic materials are applied for a quieter ride and burl-wood and satin-nickel accents are added, along with special leather. A rear-locking differential is included, with traction assist installed on rear-drive models. A load-leveling suspension includes an air compressor for inflating both beach toys and topping off tires. Also on hand is a premium Bose audio system, heated power seats, leather/wood trimmed steering wheel and rain sensing wipers.
