For enhanced safety, the front and rear seat shoulder belts of the Jeep Wrangler 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 BMW X3 doesn’t offer pretensioners for its rear seat belts.
For enhanced safety, the front seat shoulder belts of the Jeep Wrangler 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 BMW X3 doesn’t offer height-adjustable 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 Wrangler 4-Door are reminded to check the back seat if they opened the rear door before starting out. The X3 doesn’t offer a back seat reminder.
To provide maximum traction and stability on all roads, Full-Time Four-Wheel Drive is standard on the Wrangler. But it costs extra on the X3.
Both the Wrangler and the X3 have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, plastic fuel tanks, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, rearview cameras, available crash mitigating brakes, daytime running lights, blind spot warning systems, rear parking sensors and rear cross-path warning.
