For enhanced safety, the front seat shoulder belts of the Buick Envision 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 BMW X5 doesn’t offer height-adjustable seat belts.
To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the Envision. But it costs extra on the X5.
Both the Envision and the X5 have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front seatbelt pretensioners, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning and available front parking sensors.
