Safety Comparison

For better protection of the passenger compartment, the Enclave uses safety cell construction with a three-dimensional high-strength frame that surrounds the passenger compartment. It provides extra impact protection and a sturdy mounting location for door hardware and side impact beams. The Tahoe uses a body-on-frame design, which has no frame members above the floor of the vehicle.

Both the Enclave and the Tahoe have standard driver and passenger frontal airbags, front side-impact airbags, front seat center airbag, side-impact head airbags, front seatbelt pretensioners, height adjustable front shoulder belts, plastic fuel tanks, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, rearview cameras, available all wheel drive, collision warning systems, lane departure warning systems, blind spot warning systems and rear cross-path warning.

The National Highway Traffic Safety Administration does 35 MPH front crash tests on new vehicles. In this test, results indicate that the Buick Enclave is safer than the Chevrolet Tahoe:

Instrumented handling tests conducted by the National Highway Traffic Safety Administration and analysis of its dimensions indicate that the Enclave, with its four-star roll-over rating, is 5.3% to 7.4% less likely to roll over than the Tahoe, which received a three-star rating.

Warranty Comparison

The Enclave comes with a full 4 year/50,000 mile basic warranty, which covers the entire truck and includes 24 hour roadside assistance. The Tahoe’s 3 year/36,000 mile basic warranty expires 1 year and 14,000 miles sooner.

Buick’s powertrain warranty covers the Enclave 1 year and 10,000 miles longer than Chevrolet covers the Tahoe. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 6 years or 70,000 miles. Coverage on the Tahoe ends after only 5 years or 60,000 miles.

The Enclave’s 6 year corrosion warranty has no mileage limitations, but the corrosion warranty on the Tahoe runs out after 100,000 miles.

Reliability Comparison

For smoother operation, better efficiency and fewer moving parts, the Enclave has an overhead cam design, rather than the old pushrod design of the engine in the Tahoe.

To reliably power the ignition and other systems and to recharge the battery, the Enclave has a standard 170-amp alternator. The Tahoe’s 150-amp alternator isn’t as powerful.

To reliably start during all conditions and help handle large electrical loads, the Enclave has a standard 730-amp battery. The Tahoe’s 720-amp battery isn’t as powerful.

A reliable vehicle saves its owner time, money and trouble. Nobody wants to be stranded or have to be without their vehicle while it’s being repaired. Consumer Reports predicts that the Enclave’s reliability will be 123% better than the Tahoe.

J.D. Power and Associates’ 2016 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Buick vehicles are more reliable than Chevrolet vehicles. J.D. Power ranks Buick third in reliability, above the industry average. With 19 more problems per 100 vehicles, Chevrolet is ranked 6th.

Motor Trend

Tires and Wheels Comparison

The Enclave’s standard tires provide better handling because they have a lower 60 series profile (height to width ratio) that provides a stiffer sidewall than the Tahoe LS/LT’s standard 65 series tires.

For better ride, handling and brake cooling the Enclave has standard 19-inch wheels. Smaller 18-inch wheels are standard on the Tahoe LS/LT.

Suspension and Handling Comparison

For superior ride and handling, the Buick Enclave has fully independent front and rear suspensions. An independent suspension allows the wheels to follow the road at the best angle for gripping the pavement, without compromising ride comfort. The Chevrolet Tahoe has a solid rear axle, with a non-independent rear suspension.

For a smoother ride and more stable handling, the Enclave’s wheelbase is 2.9 inches longer than on the Tahoe (118.9 inches vs. 116 inches).

The Enclave AWD handles at .79 G’s, while the Tahoe Premier 4x4 pulls only .76 G’s of cornering force in a Car and Driver skidpad test.

Chassis Comparison

The Buick Enclave may be more efficient, handle and accelerate better because it weighs about 650 to 700 pounds less than the Chevrolet Tahoe.

Unibody construction makes the Enclave’s chassis much stiffer, which contributes to better handling, and enables softer springs to be used for a better ride. Unibody construction’s stiffness also contributes to better durability and less body squeaks and rattles. The Tahoe doesn’t use unibody construction, but a body-on-frame design.

As tested by Car and Driver while at idle, the interior of the Enclave AWD is quieter than the Tahoe Premier 4x4 (38 vs. 39 dB).

Passenger Space Comparison

The Enclave has .7 inches more rear headroom and 8.4 inches more third row legroom than the Tahoe.

Cargo Capacity Comparison

The Enclave’s cargo area provides more volume than the Tahoe.

A low lift-over cargo hatch design makes loading and unloading the Enclave easier. The Enclave’s cargo hatch lift-over height is 31.2 inches, while the Tahoe’s liftover is 35.9 inches.

The Enclave’s cargo area is larger than the Tahoe’s in almost every dimension:

Ergonomics Comparison

To help drivers see further while navigating curves, the Enclave offers optional adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle. The Tahoe doesn’t offer cornering lights.

Economic Advantages Comparison

According to The Car Book by Jack Gillis, the Enclave is less expensive to operate than the Tahoe because it costs $72 less to do the manufacturer’s suggested maintenance for 50,000 miles. Typical repairs cost much less on the Enclave than the Tahoe, including $62 less for a water pump, $491 less for an alternator, $273 less for a fuel pump and $47 less for front struts.

IntelliChoice estimates that five-year ownership costs (depreciation, financing, insurance, fuel, fees, repairs and maintenance) for the Buick Enclave will be $756 to $3562 less than for the Chevrolet Tahoe.

Recommendations Comparison

Consumer Reports® recommends the Buick Enclave, based on reliability, safety and performance. The Chevrolet Tahoe isn't recommended.
