For enhanced safety, the front seat shoulder belts of the Acura RDX 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 Ford Bronco doesn’t offer height-adjustable seat belts.
The Acura RDX has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags help 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 Bronco doesn’t offer knee airbags.
With its standard Collision Mitigation Braking System, the Acura RDX is better at preventing collisions with pedestrians than the Ford Bronco, according to the Insurance Institute for Highway Safety:

Over 200 people are killed each year when backed over by motor vehicles. The RDX offers optional Low Speed Autonomous Emergency Braking that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The Bronco doesn’t offer backup collision prevention brakes.
The Acura RDX comes with a standard Surround-View Camera System and it also offers an optional rear camera washer to make backing always safe, regardless of road dirt or grime, while the Ford Bronco doesn’t offer a camera washer, requiring manual cleaning.
To help make backing out of a parking space safer, the RDX has standard Rear Cross Traffic Monitor, helping the driver avoid collisions. Only the Bronco Big Bend/Outer Banks/Badlands/Stroppe/Raptor/Heritage offers Cross Traffic Alert.
For better protection of the passenger compartment, the RDX uses safety cell construction with a three-dimensional high-strength frame that surrounds the passenger compartment. It provides extra impact protection and a sturdy mounting location for door hardware and side impact beams. The Bronco uses a body-on-frame design, which has no frame members above the floor of the vehicle.
Both the RDX and the Bronco have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, plastic fuel tanks, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, rearview cameras and available around view monitors.
The National Highway Traffic Safety Administration does 35 MPH front crash tests on new vehicles. In this test, results indicate that the Acura RDX is safer than the Ford Bronco:

The Insurance Institute for Highway Safety rates the general design of front seat head restraints for their ability to protect front seat occupants from whiplash injuries. The IIHS also performs a dynamic test on those seats with “good” or “acceptable” geometry. In these ratings, the RDX is safer than the Bronco:

Instrumented handling tests conducted by the National Highway Traffic Safety Administration and analysis of its dimensions indicate that the RDX, with its four-star roll-over rating, is 10.6% less likely to roll over than the Bronco, which received a three-star rating.
