For enhanced safety, the front seat shoulder belts of the Mazda MX-30 are height-adjustable to accommodate a wide variety of driver and passenger heights. A better fit can prevent injuries and the increased comfort also encourages passengers to buckle up. The Chevrolet Bolt doesn’t offer height-adjustable 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 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 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’s blind spot costs extra.
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 doesn’t offer a driver alert monitor.
Both the MX-30 and the Bolt 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, front wheel drive, 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.
