Both the ZDX and Corsair have child safety locks to prevent children from opening the rear doors. The ZDX has power child safety locks, allowing the driver to activate and deactivate them from the driver's seat and to know when they're engaged. The Corsair’s child locks have to be individually engaged at each rear door with a manual switch. The driver can’t know the status of the locks without opening the doors and checking them.
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 ZDX are reminded to check the back seat if they opened the rear door before starting out. The Corsair doesn’t offer a back seat reminder.
To help make backing out of a parking space safer, the ZDX has standard Rear Cross Traffic Alert with Rear Cross Traffic Braking, systems which detect vehicles approaching from the sides and can automatically apply the brakes to prevent a collision. Rear Cross Traffic Braking costs extra on the Corsair.
Both the ZDX and the Corsair have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee 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, blind spot warning systems, rearview cameras, rear cross-path warning and available around view monitors.
The Acura ZDX weighs 928 to 2367 pounds more than the Lincoln Corsair. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
