2004 Envoy SLT XUV 4WD Road Test

A 2-wheel drive version of the Envoy XUV is available; however GM anticipates much greater demand for the 4-wheel drive model. And when it comes to off-roading, or just getting through the difficulties sometimes foisted upon us by Mother Nature, the Autotrac system aboard the 4WD Envoy provides the best of all modes of traction within the

world of SUVs. A small dial on the dash enables the selection of standard two-wheel drive, which sends the engine's power to the locking rear differential. Click the dial to A4WD and the wheelspin sensing automatic all-wheel drive system takes over and diverts torque away from the spinning wheels, delivering instead to the wheels with grip.

For serious off-roading, or the worst of road conditions, a further two clicks of the dial will engage all four wheels

into the driving force in either a low range or high range set of gears - thanks to an electronically controlled transfer case. The option of selecting between all-wheel drive and full time four-wheel drive, hi or lo, is really quite magnificent and exceptionally functional.

With a curb weight just north of 5,000 pounds, the Envoy XUV requires a fair apportion of torque for gratifying motivation. With a choice of two strong contenders under the hood, it won't disappoint. My tester benefited from extra horses and torque of the optional Vortec 5.3-liter V8. With a galloping 290-horsepower in its stable and 325 lb-ft of torque, the V8 Vortec seldom had to do more than slouch about to keep the XUV underway. When acceleration was demanded, or steep hills arose, the Vortec woke up and performed admirably with little fanfare or reluctance.
