The iX’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Bolt EUV doesn’t offer pre-crash pretensioners.
Both the iX and Bolt EUV have child safety locks to prevent children from opening the rear doors. The iX has power child safety locks, allowing the driver to activate and deactivate them from the driver's seat and to know when they're engaged. The Bolt EUV’s child locks have to be individually engaged at each rear door with a manual switch. The driver can’t know the status of the locks without opening the doors and checking them.
The iX has a standard PostCrash iBrake, 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 iX has a standard Active Park Distance Control 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 iX offers all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The Bolt EUV doesn’t offer all-wheel drive.
The iX 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 and moves the vehicle back into its lane. 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 iX has standard Cross Traffic Warning with braking function and automatically engage the brakes. 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 iX’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 iX and the Bolt EUV have standard driver and passenger frontal airbags, front and rear side-impact airbags, driver and front passenger knee 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, rearview cameras and available around view monitors.
The BMW iX weighs 1944 to 2089 pounds more than the Chevrolet Bolt EUV. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
