For enhanced safety, the front and rear seat shoulder belts of the Mazda MX-30 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 Chevrolet Bolt EUV doesn’t offer pretensioners for its rear seat belts.
The MX-30 has standard Whiplash-Reducing Headrests, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the Whiplash-Reducing Headrests system moves the headrests forward to prevent neck and spine injuries. The Bolt EUV doesn’t offer a whiplash protection system.
Over 200 people are killed each year when backed over by motor vehicles. The MX-30 has standard Smart Brake Support-Rear that uses rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The Bolt EUV doesn’t offer backup collision prevention brakes.
The MX-30 has a standard blind spot warning system which 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 MX-30 has a standard rear cross-path warning system, which uses sensors in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. Rear cross-path warning costs extra on the Bolt EUV.
The MX-30’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 MX-30 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 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.
