The CX-5 has a standard Secondary Collision Reduction System, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The Encore GX doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.
Over 200 people are killed each year when backed over by motor vehicles. The CX-5 has a standard Rear Smart Brake Support that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The Encore GX doesn’t offer backup collision prevention brakes.
To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the CX-5. But it costs extra on the Encore GX.
Both the CX-5 and Encore GX have Rear Cross Traffic Alert, but the CX-5 has Smart Braking Support - Rear Crossing (automatically applies the brakes) to better prevent a collision when backing near traffic. The Encore GX’s Rear Cross Traffic Alert doesn’t automatically brake.
The CX-5’s driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The Encore GX doesn’t offer a driver alert monitor.
Both the CX-5 and the Encore GX have standard driver and passenger frontal airbags, front and rear side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front and rear 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 around view monitors.
The Mazda CX-5 weighs 601 to 833 pounds more than the Buick Encore GX. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
