In the past twenty years hundreds of infants and young children have died after being left in vehicles, usually by accident. When turning the vehicle off, drivers of the Bolt are reminded to check the back seat if they opened the rear door before starting out. The EV4 doesn’t offer a back seat reminder.
The Bolt has standard Post Collision Braking, which automatically apply the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The EV4 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 Bolt has standard Reverse Automatic Braking that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The EV4 doesn’t offer backup collision prevention brakes.
The Bolt offers an optional 360 degree parking monitor to allow the driver to see objects all around the vehicle on a screen. The EV4 only offers a rear monitor.
To help make backing out of a parking space safer, the Bolt’s standard Rear Cross Traffic Alert uses sensors in the rear to alert the driver to vehicles approaching from the side and Rear Cross Traffic Braking automatically engages the brakes to help avoid a collision. The EV4 doesn’t offer a rear cross-path warning system.
The Bolt has standard OnStar®, which uses a global positioning satellite (GPS) receiver and a cellular system to get turn-by-turn driving directions or send emergency personnel to the scene if any airbags deploy. The EV4 doesn’t offer a GPS response system, only a navigation computer with no live response for emergencies, so if you’re involved in an accident and you’re incapacitated help may not come as quickly.
Both the Bolt and the EV4 have standard driver and passenger frontal airbags, front wheel drive, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, lane departure warning systems, rearview cameras and available driver alert monitors.
