For enhanced safety, the front and rear seat shoulder belts of the Hyundai Sonata 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 Toyota Corolla doesn’t offer pretensioners for its rear seat belts.
In the past twenty years hundreds of infants and young children have died after being left in vehicles, usually by accident. When turning the vehicle off, drivers of the Sonata are reminded to check the back seat if they opened the rear door before starting out. The Corolla doesn’t offer a back seat reminder.
The Sonata offers all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The Corolla doesn’t offer all-wheel drive.
The Sonata 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 Corolla’s blind spot costs extra.
To help make backing out of a parking space safer, the Sonata has standard Rear Cross-Traffic Collision Warning and Rear Cross-Traffic Collision-Avoidance Assist automatically engages the brakes to help avoid a collision. Toyota charges extra for Rear Cross-Traffic Alert on the Corolla and the Corolla’s Rear Cross-Traffic Alert does not include automatic braking.
Both the Sonata and the Corolla have standard driver and passenger frontal airbags, front and rear side-impact airbags, driver knee airbags, side-impact head airbags, front wheel drive, height adjustable front shoulder belts, plastic fuel tanks, 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.
