For enhanced safety, the front seat shoulder belts of the Chevrolet Tahoe are height-adjustable to accommodate a wide variety of driver and passenger heights. A better fit can prevent injuries and the increased comfort also encourages passengers to buckle up. The Buick Enclave doesn’t offer height-adjustable front seat belts.

The Tahoe offers all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The Enclave doesn’t offer all-wheel drive.

Both the Tahoe and the Enclave have standard driver and passenger frontal airbags, front side-impact airbags, front seat center airbag, side-impact head airbags, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, rearview cameras, available lane departure warning systems, blind spot warning systems, around view monitors and rear cross-path warning.

An engine control system that can shut down some of the engine’s cylinders helps improve the Tahoe V8’s fuel efficiency. The Enclave doesn’t offer a system that can shut down part of the engine.

For better traction, the Tahoe has larger standard tires than the Enclave (265/65R18 vs. 255/65R18). The Tahoe’s optional tires are larger than the largest tires available on the Enclave (275/65R20 vs. 255/65R18).

The Tahoe’s optional tires provide better handling because they have a lower 50 series profile (height to width ratio) that provides a stiffer sidewall than the Enclave’s optional 55 series tires.

For better ride, handling and brake cooling the Tahoe offers optional 22-inch wheels. The Enclave’s largest wheels are only 20-inches.

The Tahoe has a standard full size spare tire so a flat doesn’t interrupt your trip. A full size spare isn’t available on the Enclave; it requires you to depend on a temporary spare, which limits mileage and speed before replacement.

The Tahoe Z71/High Country has a standard automatic front and rear load leveling suspension to keep ride height level with a heavy load or when towing. The Tahoe’s height leveling suspension allows the driver to raise ride height for better off-road clearance and then lower it again for easier entering and exiting and better on-road handling. The Enclave doesn’t offer a load leveling suspension.

For better handling and stability, the track (width between the wheels) on the Tahoe is 1.2 inches wider in the front and 1.3 inches wider in the rear than on the Enclave.

For better maneuverability, the ’s turning circle is 39 feet tighter than the Enclave’s ( feet vs. 39 feet).

The Tahoe 4WD with optional equipment can be flat towed on all four wheels (dinghy towed), allowing recreational vehicle owners to bring it with them on the road. When they reach their destination, the Tahoe can be unhitched and driven around locally. The Enclave can’t be towed flat on the ground.

The engine in the Tahoe is mounted longitudinally (North-South), instead of sideways, as in the Enclave. This makes it easier to service and maintain, because there are no rear spark plugs and the accessory belts are in front.

The Tahoe’s instruments include an oil pressure gauge and a temperature gauge - which could save your engine! Often ‘idiot lights’ don’t warn you until damage has been done. The Enclave does not have an oil pressure gauge.

The Tahoe (except LS/LT/RST/Z71) offers an available heads-up display that projects speed and other key instrumentation readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The Enclave doesn’t offer a heads-up display.

The Tahoe’s front power windows open or close with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside of the car. The Enclave’s front passenger window doesn’t close automatically.

The Tahoe’s rain-sensitive wipers adjust their speed and turn on and off automatically based on the amount of rainfall on the windshield. This allows the driver to concentrate on driving without constantly adjusting the wipers. The Enclave’s manually variable intermittent wipers have to be constantly adjusted.
