For enhanced safety, the front and rear seat shoulder belts of the Mazda CX-30 have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision. The Kia Soul doesn’t offer pretensioners for its rear seat belts.
The Mazda CX-30 has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags helps prevent the driver and front passenger from sliding under their seatbelts or the main frontal airbags; this keeps them better positioned during a collision for maximum protection. Knee airbags also help keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The Soul doesn’t offer knee airbags.
The CX-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 Soul doesn’t offer a whiplash protection system.
Over 200 people are killed each year when backed over by motor vehicles. The CX-30 Turbo Premium Plus has standard Rear Smart Brake Support that use rear sensors to monitor for objects to the rear and automatically apply the brakes to prevent a collision. The Soul doesn’t offer automatic braking for stationary objects directly to the rear.
The CX-30 has all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The Soul doesn’t offer all-wheel drive.
The CX-30 Turbo Premium Plus has a standard 360° View Monitor to allow the driver to see objects all around the vehicle on a screen. The Soul only offers a rear monitor.
The CX-30 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. A system to reveal vehicles in the Soul’s blind spot costs extra.
To help make backing out of a parking space safer, the CX-30 has standard Rear Cross Traffic Alert and Smart Braking Support - Rear Crossing on the Turbo Premium Plus automatically engages the brakes to help avoid a collision. Kia charges extra for Rear Cross-Traffic Collision Warning on the Soul.
The CX-30 has standard E911 Automatic Emergency Notification, which uses a global positioning satellite (GPS) receiver and a cellular system to send emergency personnel to the scene if any airbags deploy. The Soul 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 CX-30 and the Soul have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, 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 driver alert monitors.
The Mazda CX-30 weighs 421 to 639 pounds more than the Kia Soul. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts. Crosswinds also affect lighter cars more.
