When descending a steep, off-road slope, the Envision’s standard Hill Descent Control allows you to creep down safely. The CX-30 doesn’t offer Hill Descent Control.
The Buick Envision comes with a standard HD Surround Vision, while the Mazda CX-30 doesn’t offer a camera washer, requiring manual cleaning.
To help make backing out of a parking space safer, the Envision has standard Rear Cross Traffic Alert with Rear Cross Traffic Braking, systems which detect vehicles approaching from the sides and can automatically apply the brakes to prevent a collision. Only the CX-30 Preferred/Carbon/Aire/Premium offers Smart Braking Support - Rear Crossing.
Both the Envision and the CX-30 have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front and rear seatbelt pretensioners, height adjustable front shoulder belts, four-wheel antilock brakes, all wheel drive, 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.
The Buick Envision weighs 413 to 690 pounds more than the Mazda CX-30. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
