For enhanced safety, the front seat shoulder belts of the Mazda CX-5 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 Envista doesn’t offer height-adjustable seat belts.
The CX-5 has standard Whiplash-Reducing Headrests, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the Whiplash-Reducing Headrests system moves the headrests forward to prevent neck and spine injuries. The Envista doesn’t offer a whiplash protection system.
Over 200 people are killed each year when backed over by motor vehicles. The CX-5 Turbo Signature has standard Smart Brake Support-Rear that use rear sensors to monitor for objects to the rear and automatically apply the brakes to prevent a collision. The Envista doesn’t offer backup collision prevention brakes.
The CX-5 has all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The Envista doesn’t offer all-wheel drive.
The CX-5 Turbo Signature has a standard 360° Monitor to allow the driver to see objects all around the vehicle on a screen. The Envista only offers a rear monitor and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the front or sides.
The CX-5 has a standard blind spot warning system that uses sensors to alert the driver to objects in the vehicle’s blind spots where the side view mirrors don’t reveal them. A system to reveal vehicles in the Envista’s blind spot costs extra.
To help make backing out of a parking space safer, the CX-5 has standard Rear Cross Traffic Alert, helping the driver avoid collisions. Buick charges extra for Rear Cross Traffic Alert on the Envista.
The CX-5 Turbo Signature’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 Envista doesn’t offer a driver alert monitor.
Both the CX-5 and the Envista have standard driver and passenger frontal airbags, front side-impact 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 and rearview cameras.
The Mazda CX-5 weighs 542 to 734 pounds more than the Buick Envista. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts. Crosswinds also affect lighter cars more.
