For enhanced safety, the front and rear seat shoulder belts of the Toyota bZ4X have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision. The Chevrolet Bolt EUV doesn’t offer pretensioners for its rear seat belts.
The bZ4X has a standard Secondary Collision Brake, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The Bolt EUV 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 bZ4X has a standard Parking Support Brake that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The Bolt EUV doesn’t offer backup collision prevention brakes.
The bZ4X has all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The Bolt EUV doesn’t offer all-wheel drive.
When descending a steep, off-road slope, the bZ4X AWD’s standard Downhill Assist Control allows you to creep down safely. The Bolt EUV doesn’t offer Downhill Assist Control.
The bZ4X 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 Bolt EUV’s blind spot costs extra.
To help make backing out of a parking space safer, the bZ4X has standard Rear Cross-Traffic Alert and Parking Support Brake automatically engages the brakes to help avoid a collision. Chevrolet charges extra for Rear Cross Traffic Alert on the Bolt EUV and the Bolt EUV’s Rear Cross Traffic Alert does not include automatic braking.
The bZ4X’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 Bolt EUV doesn’t offer a driver alert monitor.
Both the bZ4X and the Bolt EUV have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front wheel drive, 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, rearview cameras and available around view monitors.
The Toyota bZ4X weighs 551 to 784 pounds more than the Chevrolet Bolt EUV. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
