In a Vehicle-to-Vehicle Frontal Crash Prevention 2.0 test conducted by the Insurance Institute for Highway Safety (IIHS), the Ford Bronco achieved a “Acceptable” rating - the second highest possible - for its performance in forward collision warning and automatic braking systems, demonstrating its excellent capabilities in preventing collisions. The Jeep Wrangler has not been tested.
The Bronco has standard Post Collision Braking, which automatically apply the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The Wrangler doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.
The Bronco Big Bend/Outer Banks/Badlands/Stroppe/Raptor/Heritage’s lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane and gently nudges the vehicle back towards its lane. The Wrangler doesn’t offer a lane departure warning system.
The Bronco (except Base/Big Bend/Heritage) offers an optional 360-Degree Camera to allow the driver to see objects all around the vehicle on a screen. The Wrangler only offers a rear monitor and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the front or sides.
The Bronco (except Base)’s optional 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 Wrangler doesn’t offer a driver alert monitor.
Both the Bronco and the Wrangler have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front and rear seatbelt pretensioners, plastic fuel tanks, four-wheel antilock brakes, four-wheel drive, traction control, electronic stability systems to prevent skidding, rearview cameras, available blind spot warning systems and rear cross-path warning.
The National Highway Traffic Safety Administration does 35 MPH front crash tests on new vehicles. In this test, results indicate that the Ford Bronco is safer than the Jeep Wrangler:

New test not comparable to pre-2011 test results. More stars = Better. Lower test results = Better.
A significantly tougher test than their original offset frontal crash test, the Insurance Institute for Highway Safety does 40 MPH small overlap frontal offset crash tests. In this test, where only 25% of the total width of the vehicle is struck, results indicate that the Ford Bronco 4-Door is safer than the Wrangler 4-door:

Side impacts caused 23% of all road fatalities in 2018, down from 29% in 2003, when the Insurance Institute for Highway Safety introduced its side barrier test. In order to continue improving vehicle safety, the IIHS has started using a more severe side impact test: 37 MPH (up from 31 MPH), with a 4180-pound barrier (up from 3300 pounds). The results of this newly developed test demonstrates that the Ford Bronco 4-Door is safer than the Wrangler 4-door:

Instrumented handling tests conducted by the National Highway Traffic Safety Administration and analysis of its dimensions indicate that the Bronco is 1.1% less likely to roll over than the Wrangler.
