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.
Over 200 people are killed each year when backed over by motor vehicles. The Tahoe Premier/High Country offers optional Reverse Automatic Braking that uses rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The Enclave doesn’t offer backup collision prevention brakes.
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, side-impact head airbags, front seatbelt pretensioners, plastic fuel tanks, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, rearview cameras, available blind spot warning systems, around view monitors and rear cross-path warning.
The Chevrolet Tahoe weighs 788 to 1545 pounds more than the Buick Enclave. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
