The Lexus NX has a standard driver’s side knee airbag mounted low on the dashboard. The knee airbag helps prevent the driver from sliding under the seatbelts or the main frontal airbag; this keeps the driver better positioned during a collision for maximum protection. A knee airbag also helps keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The Sportage Hybrid doesn’t offer knee airbags.
With its standard Pre-Collision System with Pedestrian Detection, the Lexus NX is better at preventing collisions with pedestrians than the Kia Sportage Hybrid, according to the Insurance Institute for Highway Safety:

In a Vehicle-to-Vehicle Frontal Crash Prevention 2.0 test conducted by the Insurance Institute for Highway Safety (IIHS), the Lexus NX achieved a “Good” rating - the highest possible - for its performance in forward collision warning and automatic braking systems, demonstrating its excellent capabilities in preventing collisions. The Kia Sportage Hybrid has not been tested.
The Lexus NX’s rear backup camera has a standard washer for maintaining a clear view under various conditions. In contrast, the Kia Sportage Hybrid does not offer a rear camera washer, meaning its effectiveness relies on manual cleaning by the user when necessary.
The NX has a standard blind spot warning system that uses sensors to alert the driver to objects in the vehicle’s blind spots where the side view mirrors don’t reveal them. Only the Sportage Hybrid S/EX/X-Line/SX-Prestige offers a blind spot warning system.
To help make backing out of a parking space safer, the NX has standard Rear Cross-Traffic Alert and Parking Support Brake automatically engages the brakes to help avoid a collision. Only the Sportage Hybrid S/EX/X-Line/SX-Prestige offers Rear Cross-Traffic Collision Warning.
Both the NX and the Sportage Hybrid have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, front wheel drive, 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, rearview cameras, driver alert monitors and available around view monitors.
The National Highway Traffic Safety Administration does side impact tests on new vehicles. In this test, which crashes the vehicle into a flat barrier at 38.5 MPH and into a post at 20 MPH, results indicate that the Lexus NX is safer than the Kia Sportage Hybrid:

New test not comparable to pre-2011 test results. More stars = Better. Lower test results = Better.
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 Lexus NX is safer than the Sportage Hybrid:

The Lexus NX achieved a “Top Safety Pick” rating from the Insurance Institute for Highway Safety (IIHS) for the 2025 model year. This recognition was based on its impressive performance in the small overlap frontal crash test, updated moderate overlap front crash test, updated side impact crash test, headlight evaluations, and pedestrian crash prevention testing. The Sportage Hybrid has not yet been fully evaluated by the IIHS for 2025.
