Driving Impressions

The Chevrolet Tahoe rides smoothly on the open road, and it's stable and comfortable at high speeds. Although big and ponderous, the Tahoe handles well for a full-size truck. Tahoe is built on GM's full-size truck platform (GMT 800, if you must know), which forms the basis for the Silverado and Sierra pickups as well as the Suburban, Yukon and Yukon XL SUVs, and the Cadillac Escalade. It's a superb truck platform, notable for the rigidity of its hydroformed frame. Chassis rigidity is the key to achieving good handling and a smooth ride, and the Tahoe delivers on both of those scores. It handles bumpy roads well, a good test of chassis rigidity. Tahoe's front suspension is conventional in design, except for the springs. To save space, the Tahoe uses torsion bars instead of coil springs. Tahoe now comes standard with the Premium Smooth Ride suspension, which uses self-leveling rear shocks to maintain trim height for better handling when hauling heavy cargo or pulling a trailer. Our Tahoe LT had the optional Autoride suspension ($1,120), which electronically controls rear air shocks to provide real-time adjustments in suspension damping. It provided a comfortable ride on I-405, a bumpy, busy freeway in Los Angeles. Autoride also kept the Tahoe from bounding around after pulling a trailer over railroad tracks. The available Z71 package, with its off-road suspension, provides a good ride quality on gravel and washboard surfaces. We prefer it when driving on gravel roads and two-tracks. We were impressed with the Tahoe's braking ability while towing a horse trailer. Tahoe's braking system uses four-wheel discs with dual-piston calipers for good stopping performance. A dynamic proportioning system continuously balances the front and rear brakes for maximum effectiveness without activating the ABS. Once activated, the ABS allows the driver to maintain control of the steering in an emergency maneuver. Additionally, Tahoe's Hydroboost system uses pressurized oil (power steering fluid, actually) rather than the usual engine vacuum to reduce braking effort. That means more reserve power for braking under specific conditions. Hydroboost will even provide sufficient power assist to stop the vehicle if the engine stalls or is turned off. The Tahoe is relatively easy to park, and much easier than the Suburban. It's 22 inches shorter than a Suburban, and its 38.3-foot turning diameter is 4 feet tighter than the Suburban's. With its shorter wheelbase, shorter rear overhang and equal ground clearance, the Tahoe traverses gullies and other rugged terrain where the Suburban scrapes bottom. Likewise, the Tahoe is shorter and more maneuverable than the Ford Expedition. Even though the Tahoe is a fraction of an inch wider than the Expedition, I find it easier to judge the distance between the Tahoe's right front corner and a tree, making Tahoe easier to manage off-road. The Tahoe's recirculating-ball steering provides good control and feedback, even if it falls short of the rack-and-pinion steering found on the Ford Expedition and Explorer. Tahoe's power steering system is designed for durability by operating at a lower temperature range. Chevy's small-block, overhead-valve V8s are excellent. They rival Ford's overhead-cam engines for smoothness and efficiency, and deliver strong torque for towing. The standard 4.8-liter V8 cranks out 285 horsepower, while delivering decent fuel economy; a Tahoe 2WD with the Vortec 4800 earns 18 mpg on the EPA's highway mileage test. A better choice, and the one most people choose, is the 5.3-liter engine rated at 295 horsepower. It delivers strong acceleration performance and burns regular unleaded fuel. A 2005 Tahoe 4WD with the Vortec 5300 earns an EPA-estimated 13/17 mpg city/highway. If serious off-road driving is your aim, you should know that the Tahoe does not offer the capability of a Jeep Grand Cherokee, Toyota Land Cruis

Final Word

Chevrolet Tahoe is perfect for drivers who want a full-size sport-utility, but don't want to herd a Suburban every day. New features introduced in the last three model years make living with the Tahoe more convenient. Numerous engineering changes make it safer and more reliable. For many people, it's the ideal SUV.
