For enhanced safety, the front and rear seat shoulder belts of the Volvo XC40 have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The Buick Envista doesn’t offer pretensioners for its rear seat belts.
The XC40’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Envista doesn’t offer pre-crash pretensioners.
For enhanced safety, the front seat shoulder belts of the Volvo XC40 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 Volvo XC40 has a standard driver’s side knee airbag mounted low on the dashboard. The knee airbag helps prevent the driver from sliding under the seatbelts or the main frontal airbag; this keeps the driver better positioned during a collision for maximum protection. A knee airbag also helps keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The Envista doesn’t offer knee airbags.
The XC40 has standard Post-impact braking, which automatically apply the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The Envista 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 XC40 has a standard CTA Auto Brake that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The Envista doesn’t offer backup collision prevention brakes.
The XC40 has all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The Envista doesn’t offer all-wheel drive.
The XC40 offers an optional 360-Degree Surround View Camera 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.
To help make backing out of a parking space safer, the XC40 has standard Cross Traffic Alert and Braking Intervention automatically engages the brakes to help avoid a collision. Buick charges extra for Rear Cross Traffic Alert on the Envista and the Envista’s Rear Cross Traffic Alert does not include automatic braking.
The XC40’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 XC40 and the Envista have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, 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 Volvo XC40 weighs 746 to 937 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.
For its top level performance in all IIHS frontal, side, rear impact and roof-crush tests, and its standard front crash prevention system, the Insurance Institute for Highway Safety grants the XC40 the rating of “Top Safety Pick” for 2017, a rating granted to only 231 vehicles tested by the IIHS. The Envista has not been tested, yet.
