Over 200 people are killed each year when backed over by motor vehicles. The Envision has standard Reverse Automatic Braking that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The Acadia doesn’t offer backup collision prevention brakes.
To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the Envision. But it costs extra on the Acadia.
Both the Envision and Acadia have Rear Cross Traffic Alert, but the Envision has Rear Cross Traffic Braking (automatically applies the brakes) to better prevent a collision when backing near traffic. The Acadia’s Rear Cross Traffic Alert doesn’t automatically brake.
Both the Envision and the Acadia have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front seatbelt pretensioners, height adjustable front shoulder belts, 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.
