The X3’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Wrangler doesn’t offer pre-crash pretensioners.
The BMW X3 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 Wrangler doesn’t offer knee airbags.
The X3 has standard head airbag curtains for front and rear seats which act as a forgiving barrier between the driver and outboard passenger's upper bodies and the window and pillars. Combined with high-strength steel door beams and lower side airbags this system increases head protection in broadside collisions. The Wrangler doesn't offer side airbag protection for the head and are only available for the front seats.
The X3 has standard Active Head Restraints, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the Active Head Restraints system moves the headrests forward to prevent neck and spine injuries. The Wrangler doesn’t offer a whiplash protection system.
The X3 has standard City Collision Mitigation, which use forward mounted sensors to warn the driver of a possible collision ahead. If the driver doesn’t react and the system determines a collision is imminent, it automatically applies the brakes at full-force in order to reduce the force of the crash or avoid it altogether. The Wrangler offers an available collision warning system without the automated brake feature that would prevent or reduce the collision if the driver fails to react.
The X3 has a standard PostCrash iBrake, which automatically applies 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.
Over 200 people are killed each year when backed over by motor vehicles. The X3 offers optional Active Park Distance Control that uses rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The Wrangler doesn’t offer backup collision prevention brakes.
The X3’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 X3 offers an optional Surround View 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 X3 has a standard blind spot warning system which uses sensors to alert the driver to objects in the vehicle’s blind spots where the side view mirrors don’t reveal them and moves the vehicle back into its lane. A system to reveal vehicles in the Wrangler’s blind spot costs extra.
To help make backing out of a parking space safer, the X3 has a standard rear cross-path warning system, which uses sensors in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. Only the Wrangler Sport S/Sahara/Rubicon offers a rear cross-path warning system and it costs extra.
The X3’s 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.
For better protection of the passenger compartment, the X3 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 Wrangler uses a body-on-frame design, which has no frame members above the floor of the vehicle.
Both the X3 and the Wrangler have standard driver and passenger frontal airbags, front side-impact airbags, front seatbelt pretensioners, plastic fuel tanks, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, rearview cameras and available all wheel drive.
The National Highway Traffic Safety Administration does 35 MPH front crash tests on new vehicles. In this test, results indicate that the BMW X3 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 BMW X3 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 X3, with its four-star roll-over rating, is 9.5% to 10.8% less likely to roll over than the Wrangler, which received a three-star rating.
For its top level performance in IIHS driver and passenger-side small overlap frontal, moderate overlap frontal, side impact, roof strength and head restraint tests, its standard vehicle-to-vehicle front crash prevention system, its standard vehicle-to-pedestrian front crash prevention system, and its standard headlight’s “Good” rating, the Insurance Institute for Highway Safety grants the X3 its highest rating: “Top Safety Pick Plus” for 2022, a rating granted to only 96 vehicles tested by the IIHS. The Wrangler is not even a standard “Top Safety Pick.”
