The i4’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.
The i4 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 i4 offers an optional 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 i4 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 i4 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 i4 has standard Cross Traffic Warning, helping the driver avoid collisions. Chevrolet charges extra for Rear Cross Traffic Alert on the Bolt EUV.
The i4’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 i4 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 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 i4 weighs 838 to 1338 pounds more than the Chevrolet Bolt EUV. The NHTSA advises that heavier cars are much safer in collisions than their significantly lighter counterparts.
